Harder to consider: the distance between the Earth and the moon, which is 384,400 km (240,000 miles). A tennis ball would then have to be 110 x 6.7 cm = 7.37 meters (about 24 feet) from the basketball. How far away is the Moon? 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). The Earth, like most of the planets, revolves around the Sun, with a complete revolution taking 365.25 days. Why boys YELL (punk rock!!) The record for the shortest journey time to the Moon is currently held by the New Horizons spacecraft with a time of 8 hours and 35 minutes. Calendar Tools. The Earth is 93,000,000 miles away from the Sun on average and 141.6 million miles. Fight! At apogee — the farthest away it gets — the moon is 252,088 miles (405,696 km) from Earth. Therefore they can be considered fixed. How do scientists know? That distance is so large that it takes light eight minutes to reach us (remember that light travels at 300,000 kilometres per second). What lights the Moon? At its closest point (known as perigee) the Moon is only 363,104 km (225,622 miles) away. On average, the distance from Earth to the moon is about 238,855 miles. The biggest tides occur when the Sun, Moon and Earth align because the gravitational pull of the Sun and Moon combine. The first spacecraft to attempt to reach the Moon was the Soviet Union's  Luna 1 in 1959. The moon's distance is measured by bouncing laser beams off reflectors on the moon's surface that astronauts from the Apollo missions left behind. It is about 93 million miles away. Our tides are caused by the gravitational pull of the Moon and the Sun and the Earth’s rotation. Your support is vital to our work as a charity, helping us to care for your... Visit the Royal Observatory in Greenwich, London. See images of the Moon at the Insight Investment Astronomy Photographer of the Year exhibition. The retroreflector mirror left by Neil Armstrong and Edwin ‘Buzz’ Aldrin as part of the Lunar Laser Ranging Experiment. That's about three days as the Apollo flies! The moon's distance varies within its orbit. 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). The Moon moves in an elliptical orbit around the Earth, which means its distance from our planet is constantly changing. The moon is far away from Earth ... stretching an average of 239,200 miles wide, that it’d take a 747 jet aeroplane flying at top speed more than 14 days to arrive. As long as people have looked at the moon, they have wondered how far away it is from Earth. The distance between the moon and the earth varies as its orbit around the earth is elliptical – meaning the distance changes over time. 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. How far is the Moon? Take a look yourself. How far away is Mars? Moon Phase Calendar – Calculate moon phases for any year. The average distance to the moon is 382,500 kilometers. The diameter of the moon is about 2,160 miles. A tennis ball would then have to be 110 x 6.7 cm = … The moon is so far … Venus Orbits the Sun at 0.72333 astronomical unit in 0.6152 year. This distance is equivalent to the “lunar distance” measurement. Credit: NASA/Luc Viator/HalloweenNight/Affelia Wibisono. Human space travel will usually take longer than robotic ones. It is 141.6m miles (227.9m kilometres) away from the Sun. This means it’s not a constant distance away. The eccentricity of the Moon’s orbit is 0.05. The au is not the exact distance, but the average distance between the Earth and the Sun, meaning the distance may sometimes vary. Before the first lunar mission took place, the distance was calculated by a study of planetary motion or by using a telescope. That distance can vary by up to 50,000 km during a single orbit, which is why the size of the Moon in our sky varies slightly from week to week. The average distance between the Earth and the moon is 384,400 km (238,855 miles). Place the basketball on the ground. 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. You may have noticed that the full Moon always looks about the same. 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. But that might not answer your question. In fact, the moon varies between 225,622 miles and 252,088 miles due to its elliptical orbit. The Moon is the single brightest and closest object in our night skies, making it the perfect target for a spacecraft landing. 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. This article has been written by an astronomer at the Royal Observatory, Greenwich. That’s actually an interesting coincidence, since the Earth orbits about 150 million kilometers away … 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. 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’). What lights the Moon? 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. It's about a quarter of a million miles to the moon and it's about 100 million miles to the Sun, give or take. That, coupled with the lack of an atmosphere on the Moon, means the temperature changes wildly from over 100°C during the day to around -150°C at night. However, the phases of the Moon are dependent on how the Moon, Earth and Sun are placed. Not really. Thus, on average, moon-Earth separation is about 382,500 kilometers. Fight! 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. 3. Almost no effort is made to ensure that these figures are accurate. It will eventually stop receding from the Earth in about 50 billion years’ time according to theory. If you were driving at a speed of 40mph it would take approximately 5,791.375 hours to get to the Moon. Earth Orbits the Sun at 1.00000 astronomical unit once a year. 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. This means we only ever see the near side of the Moon from Earth, and never the far side. And why is that question not as simple as it sounds? The moon has an elliptical orbit around the Earth so it’s not a constant distance away. 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. The Distance Varies – The Moon is Between 221,500 Miles and 252,700 From the Earth Depending on it’s Orbit The Moon moves in an elliptical orbit around the Earth, which means its distance from our planet is constantly changing. Astronauts from the Apollo 11, 14 and 15 missions and the two Soviet Union rovers, Lunokhod 1 and Lunokhod 2, left a total of five mirrors on the surface of the Moon. Supermoons appear to be 14% larger and 30% brighter than a micromoon. That's about three days as the Apollo flies! Modern laser guided measurements have shown that the average distance to the Moon is 382,000km. The quickest was Apollo 8 which took 2 days, 21 hours and 8 minutes, while Apollo 17 took the longest with a time of 3 days, 14 hours and 41 minutes (times include the time spent in Earth orbit). After 500 million years, the Moon was orbiting about 20 Earth radii distant—some 80,000 miles away. 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. Astronomers can measure how near to a perfect circle an orbit is by calculating its 'eccentricity'. Not the Sun (video) How far away is the Moon, 3K or 225K miles? The Apollo 11 mission which took man to the moon for the first time took off on 16 July 1969 and reached the moon 100 hours later. On average, NASA estimates the Moon is about 238,855 miles (384,400km) away. Asking how far away is the Moon is another of those questions whose answer is more complicated than you might expect. In 190 BC, Hipparchus calculated the distance to the moon as 397,000km using simple trigonometry. 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.) However, the Sun would have already entered the next stage of its life long before that happens. No orbit is perfectly circular. Astronomers tend to talk about three different numbers when talking about the distance between the Earth and the Moon. Calendar for 2021 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. At its apogee, it's 252,088 miles (405,696 km) from Earth. The Distance Calculator can find distance between any two cities or locations available in The World Clock. It is 141.6m miles (227.9m kilometres) away from the Sun. So how far away would a tennis ball Moon have to be from the basketball Earth to be to scale? How much of it we see depends on its position in relation to Earth and the Sun. The distance is calculated in kilometers, miles and nautical miles, and the initial compass bearing/heading from the origin to the destination. So how far away would a tennis ball Moon have to be from the basketball Earth to be to scale? [/caption] The Moon, on average, is about 150 million kilometers away from the Sun. This difference comes from how you measure the motions of objects in space. However, this depends on whether the Moon is in apogee or perigee - and what kind of rocket car you have of course. Sunrise Calculator – Find times for sunrise, sunset and more. Minumum (perigee) and maximum (apogee) distances from the Moon to the Earth. [/caption] The Moon, on average, is about 150 million kilometers away from the Sun. These two figures differ by 42 592 km (26 465 miles) - more than three times larger than the diameter of the Earth! The moon is approximately 240,000 miles away from the Earth. Astronomers on Earth can reflect laser beams off these mirrors and record the time it takes for the laser to return. Distance Calculator – How far is it? 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. 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 » ... the distance between the Earth and the moon, which is 384,400 km (240,000 miles). If the moon were 6000 miles from the Earth, then it would seem to grow and shrink in size as it passed by (such an effect can be seen on Mars, where the moon really does orbit close to the planet) And the Sun is further still. This would mean that in the far future, total. This means you could fit up to 30 Earth’s in the space between the Moon and our home-world. The Earth-Moon distance would then be half of this value.
