Earth and the Moon seen by Galileo, Dec. 16, 1992 (NASA) 21 years ago today, December 16th, 1992, NASA’s Galileo spacecraft took this image of Earth and the Moon from a distance of about 3.9 million miles (6.2 million km). Credit: Marcoaliaslama. On average, NASA estimates the Moon is about 238,855 miles (384,400km) away. Minumum (perigee) and maximum (apogee) distances from the Moon to the Earth. As there are no truly fixed points in space to measure against, you are forced to use objects that are considered not to move to within a reasonable level of uncertainty. See images of the Moon at the Insight Investment Astronomy Photographer of the Year exhibition. But the Moon’s orbit around the Earth also happens to be elliptical, meaning the distance between the Earth and the Moon changes over time. That's about three days as the Apollo flies! It is located at one of the foci of the Moon’s elliptical orbit, so is closer to one edge of the orbit than the other. After 500 million years, the Moon was orbiting about 20 Earth radii distant—some 80,000 miles away. 2. Astronomers tend to talk about three different numbers when talking about the distance between the Earth and the Moon. You might feel like you've got a good grasp on how far away the Moon is, but you probably don't. These two figures differ by 42 592 km (26 465 miles) - more than three times larger than the diameter of the Earth! And at its most distant point (called apogee) the Moon gets to a distance of 406,696 km (252,088 miles). Mars, also known as the Red Planet, is 33.9million miles (54.6m kilometres) away from Earth. Starting Point: Destination: in You need to spell out the whole name of the place without abbreviation. The Moon moves in an elliptical orbit around the Earth, which means its distance from our planet is constantly changing. Similarly, the newly formed Moon would also have been affected and had its own lunar magma ocean; its depth is estimated from about 500 km (300 miles) to 1,737 km (1,079 miles). At differe… As it expands into a red giant star in 5 billion years or so, it will push the Moon back towards the Earth causing it to disintegrate due to strong tidal forces. As an example, the distance between the planet Mercury and Earth can range from 77 million km at the closest point, to as far as 222 million km at the farthest. [/caption] The Moon, on average, is about 150 million kilometers away from the Sun. To get to the Moon would take a little longer though, since it’s 400,000km (250,000 miles) away – around 10 times the circumference of the Earth. A tennis ball would then have to be 110 x 6.7 cm = … That’s actually an interesting coincidence, since the Earth orbits about 150 million kilometers away … The Distance Varies – The Moon is Between 221,500 Miles and 252,700 From the Earth Depending on it’s Orbit The Moon's orbit is also … The full Moon will look slightly bigger if it occurs during perigee (sometimes called a supermoon) and slightly smaller at apogee (a micromoon). The first spacecraft to attempt to reach the Moon was the Soviet Union's Luna 1 in 1959. During the time the Moon orbits the Earth, the Earth has moved on in its orbit around the Sun. The arc that runs through the moon’s diameter has an angle of 0.56 degrees and an arc length of 2,160 miles (the diameter). What is the distance to moon how far away is the moon nasa e weather minds clroom our moon that moon and earth gif is totally real How Far Is The Moon EWhat Is The Distance Between Earth And Moon QuoraHow Far Away Is The Moon Nasa E Place Science For KidsFrom A Million Miles… Read More » Almost no effort is made to ensure that these figures are accurate. The Moon moves in an elliptical orbit around the Earth, which means its distance from our planet is constantly changing. On average the moon is 380,000 km (235,000 miles) from the Earth, a distance of about 110 times its own diameter. This is sometimes known as the “dark side” of the Moon - not because it actually is dark, but because it was mysterious and unknown until humans explored it. On average, the Earth and Moon are about 150 million kilometres (or 93 million miles) from the Sun! The distance between them is only 363 104 km (225 623 miles). If the Earth were the size of a basketball and the moon a tennis ball, how far apart would they be? Chris - The Moon is pretty close. Venus Orbits the Sun at 0.72333 astronomical unit in 0.6152 year. Before the first lunar mission took place, the distance was calculated by a study of planetary motion or by using a telescope. It looks a lot closer than it actually is. What lights the Moon? The Distance Varies – The Moon is Between 221,500 Miles and 252,700 From the Earth Depending on it’s Orbit How far is the Earth from the moon? That depends on the Earth’s position with Mars. In fact if you look at any phase of the Moon, it will always show the same features, though not all of the features will be lit up. ... (3 million miles) away from the Earth. So how far away would a tennis ball Moon have to be from the basketball Earth to be to scale? Its distance therefore varies from 221,441 miles at perigee (closest distance) to 252,724 miles at apogee (farthest). Things like planets are huge, but the distances between them are even bigger. This would mean that in the far future, total solar eclipses would be a thing of the past as the Moon will appear to be smaller: therefore, its disc will not be large enough to completely obscure the Sun. As it expands into a red giant star in 5 billion years or so, it will push the Moon back towards the Earth causing it to disintegrate due to strong tidal forces. For example: DO NOT use St. Louis USE Saint Louis. This seems really fast, but objects in space are so far away that it takes a lot of time for their light to reach us. This means we only ever see the near side of the Moon from Earth, and never the far side. Your support is vital to our work as a charity, helping us to care for your... Visit the Royal Observatory in Greenwich, London. Space is big. The average distance between the Earth and the Moon is 384 400 km (238 855 miles). It was very fuel efficient but did take 13.5 months to complete its journey! At its closest point (known as perigee) the Moon is only 363,104 km (225,622 miles) away. Credit: NASA/Luc Viator/HalloweenNight/Affelia Wibisono. But if you took an average distance, the moon is approximately 238,855 miles (384,400 km). If you take an average distance, the moon is approximately 238,855 miles (384,400 km) away from the Earth. The orbit of the Earth is elliptical or oval in shape, or like a stretched circle, with the Sun roughly at the center of the orbit. The distance varies because the moon travels around Earth in an elliptical orbit. It is 141.6m miles (227.9m kilometres) away from the Sun. If you were driving at a speed of 40mph it would take approximately 5,791.375 hours to get to the Moon. Harder to consider: the distance between the Earth and the moon, which is 384,400 km (240,000 miles). How do scientists know? Closest Approach (Perigee) is, * Distances are approximate. The distance between the moon and the earth varies as its orbit around the earth is elliptical – meaning the distance changes over time. At its furthest point from the Earth, the Moon is about 405 696 km (252 088 miles) away and astronomers say that the Moon is at apogee (‘apo’ means ‘away’). The simple answer is that the Sun is the closest star to Earth, about 93 million miles away. So how did Hipparchus achieve this remarkably … Right now the moon is more than 238,000 miles from Earth, but when it formed, it was just 14,000 miles away. 3. It is a scientific fact that the moon averages a distance of around 238,855 miles (384,400 km) from Earth, but conspiracists are disputing this figure. For only the third time ever, Earth has been photographed from the outer Solar System. In 190 BC, Hipparchus calculated the distance to the moon as 397,000km using simple trigonometry. The Moon Exhibition Book: A Celebration of our Celestial Neighbour. Calendar Tools. Neap tides are smaller and occur when the Sun and Moon are perpendicular to each other. How much of it we see depends on its position in relation to Earth and the Sun. would be a thing of the past as the Moon will appear to be smaller: therefore, its disc will not be large enough to completely obscure the Sun. Earth And Moon From Mercury Nasa Lies Exposed Moon Is 4 Miles From Earth Claims This Is Our Pla From A Million Miles Away Universe Today Earth And Moon Photographed From 900 Million Miles Away The It is so far away that light from the Sun, traveling at a speed of 186,000 miles (300,000 kilometers) per second, takes about 8 minutes to reach us. Why boys YELL (punk rock!!) On average, the distance from Earth to the moon is about 238,855 miles. It looks a lot closer than it actually is. Light travels at a speed of 186,000 miles (or 300,000 km) per second. At perihelion, the Earth’s closest distance to the Sun, the distance between the Sun and the Earth is 91.4 million miles. Bloody bare knuckle boxing (video) Buddhism and God (cartoon) Griffith Observatory, Hollywood; The Mushroom Kingdom of Fungi (video) Hidden continents on Earth, ice walls (video) Buddhism arrives in Sri Lanka: Poson (L.A.) It is 141.6m miles (227.9m kilometres) away from the Sun. This isn't a single star, it's actually a triple-star system — three stars bound together by gravity. To make our computations simpler, let’s assume that the Sun, Earth, and Mars are in a straight line in that order. Astronomers on Earth can reflect laser beams off these mirrors and record the time it takes for the laser to return. Our Sun is the closest star to us. Some are very close, but they are all at least slightly elliptical in shape. Hipparchus first calculated the distance in 190BC using a simple method involving trigonometry and was accurate to 1,000km! After 500 million years, the Moon was orbiting about 20 Earth radii distant—some 80,000 miles away.  While the giant-impact theory explains many lines of evidence, some questions are still unresolved, most of which involve the Moon's composition. That distance is so large that it takes light eight minutes to reach us (remember that light travels at 300,000 kilometres per second). It also depends on what you want to do – passing by the Moon does not require you to slow down to enter its orbit, minimising the time it would take to get there. Moon Phase Calendar – Calculate moon phases for any year. This article has been written by an astronomer at the Royal Observatory, Greenwich. This represents Earth. Venus’ orbit is the least eccentric out of all of the planets in our Solar System and closest to a circle, with a value of 0.007. Furthest Apart (Apogee) is. Thus, on average, moon-Earth separation is about 382,500 kilometers. However, this depends on whether the Moon is in apogee or perigee - and what kind of rocket car you have of course. Fight! That means that if the Sun were to stop shining right now, we wouldn’t know for another eight minutes. The table below shows the time of lunar perigee and apogee. At its apogee, it's 252,088 miles (405,696 km) from Earth. That’s actually an interesting coincidence, since the Earth orbits about 150 million kilometers away from the Sun. And why is that question not as simple as it sounds? Note that the Earth is not at the very centre of the orbit and that the eccentricity of the orbit has been exaggerated here! However, the difference won’t be easily noticeable to the naked eye and a side by side photographic comparison is the only way to really see it. Outside of our Sun, our system's nearest neighbor is Alpha Centauri. Furthermore, the Earth is not at the very centre of the Moon’s orbit either. What lights the Moon? The moon orbits the Earth in an elliptical orbit, not circular. However, the Earth does not move round the Sun in a perfect circle. ... the distance between the Earth and the moon, which is 384,400 km (240,000 miles). The Earth is 7,926 miles 12,756 (km) in diameter. On average the moon is 380,000 km (235,000 miles) from the Earth, a distance of about 110 times its own diameter. Thus, on average, moon-Earth separation is about 382,500 kilometers. This is because the Moon spins at the same rate as it orbits around the Earth, with the exception of a couple of minor wobbles (known as libration) that brings a little more of the Moon into view. On the other hand, when the Moon is at perigee (‘peri’ means ‘near’), the Moon is at its closest approach to the Earth. Take a look yourself. The moon is 238,900 miles (384,400 km) from Earth. Not the Sun (video) How far away is the Moon, 3K or 225K miles? And at its most distant point (called apogee) the Moon gets to a distance of 406,696 km (252,088 miles). It will eventually stop receding from the Earth in about 50 billion years’ time according to theory. Human space travel will usually take longer than robotic ones. It would be – to scale, mind you – 800,000 km (480,000 miles) away: twice as far as the real Moon is from the real Earth! Place the basketball on the ground. Info:How the Moon's phases change. At half moon, the sun seems to be at $90^\circ$ to the moon. Moon Calculator – Find times for moonrise, moonset and more. That's about three days as the Apollo flies! We know how fast the laser beam is travelling (the speed of light) so we can easily calculate the distance that the laser beam has travelled. In effect, the Moon needs a couple of extra days to catch up and return to the same point in space relative to the Sun. This distance is equivalent to the “lunar distance” measurement. But what is the exact distance between the Earth and the Moon? Several forming mechanisms have been proposed, including the fission of the Moon from Earth's crust through centrifugal force (which would require too great an initial rotation rate of Earth), the gravitational capture of a pre-formed Moon (which would require an unfeasibly extended atmosphere of Earth to dissipatethe energy of the passing Moon), and the co-for… At the closest point to the Earth – so-called perigee – the Moon is an incredible 225,623 miles (363,104km) … 1. Sunrise Calculator – Find times for sunrise, sunset and more. A tennis ball would then have to be 110 x 6.7 cm = 7.37 meters (about 24 feet) from the basketball. The moon's orbit around Earth is elliptical. How far is the Moon?
