It takes 87.96 Earth days for Mercury to revolve around the sun, faster than any other planet, and 58.7 Earth days to … Join our Space Forums to keep talking space on the latest missions, night sky and more! That's more than 10 times greater than the eccentricity of Earth's orbit, which is 0.0167. An astronomical unit (au) is the average distance of the Earth from the Sun and is the most common unit for the distance calculation in the solar system. Like the moon, Mercury has very little atmosphere to stop impacts and it is covered with craters. Mercury is the closest planet to the sun, and on average, it is 57 million kilometers (35 million miles) away. Mercury, named after a Roman god, is 36 million miles away from the sun and 48 million miles from Earth. It is the smallest planet in the solar system, with a diameter of 3,031 miles. The distance from Earth to the Sun, calculated in meters is approximately 140,000,000,000 meters. This would happen when Mercury was at its furthest from the Sun, and Earth is at its closest. This isn't necessarily due to its distance from Earth: The planet orbits close to the sun, which means its light is usually washed out in the evening sky. Mercury rotates one and a half times during each orbit. Mercury live position and data. Depending on where you live worldwide, the innermost planet Mercury reaches its greatest elongation from the sun on July 29 or 30, 2017. Now that Pluto is no longer classified as a planet, Mercury is the smallest planet in the solar system. Space photos: The most amazing images this week! The Space website notes the distance of Mercury from the Sun to be approximately 28.5 million miles to 43.5 million miles. When Mercury is closest to the sun, it is only 46 million kilometers (29 million miles) distant, but when the planet is rounding the opposite focus of its orbit, it is 70 million kilometers (43 million miles) away from the sun. Mercury's highly eccentric, egg-shaped orbit takes the planet as close as 29 million miles (47 million kilometers) and as far as 43 million miles (70 million kilometers) from the Sun. There is a huge amount of different in the distances between the planets depending on their position on their orbit path. Thank you for signing up to Space. 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. Please refresh the page and try again. We already know that the distance of all the planets are generally calculated by keeping the Sun as the main location point. Orbit of Mercury relative to other planets in our solar system. The distances of all the planets from the Sun in scientific notation and exponential form- Mercury- 57 million kilometers. SpaceKids on SPACE.com provides simple, straightforward answers to really big cosmic questions. The diagram illustrates the effects of the eccentricity, showing Mercury's orbit overlaid with a circular orbit having the same semi-major axis. This page shows Mercury location and other relevant astronomical data in real time. Planetary data for Mercury *Time required for the planet to return to the same position in the sky relative to the Sun as seen from Earth. Mercury’s proximity to the Sun has also been exploited to confirm predictions made by relativity theory about the way gravity affects space and time. Mercury's orbital period would then be (88/365.25) or .241 Earth years. As a result, the angular diameter of the Sun from Mercury is much larger: about 1.4°. Planetary data for Mercury *Time required for the planet to return to the same position in the sky relative to the Sun as seen from Earth. For problems involving orbits around the Sun, it is convenient to use Earth as the standard. Mercury is an average distance of 48 million miles (77 million km) from Earth. This page shows Mercury location and other relevant astronomical data in real time. Shortest mean distance between Sun and Mercury is about 57.91 million kilometer or about 0.3871 astronomical unit (AU) [ Convert 57.91 million kilometer to different units] Mercury is … The precise distance between the two planets depends on where they are in their respective orbits. When this happens, Mercury and Earth would be … But when Mercury is moving fastest in its elliptical orbit around the Sun (and it is closest to the Sun), each rotatio… The eccentricity of Mercury's orbit, which is a measure of how much it differs from a circular orbit, is 0.2056. It takes 87.969 Earth days to complete an orbit. Rotation around the Sun: 88 Earth days; Your weight: If you weigh 100 pounds on Earth, you would weigh 38 pounds on Mercury. That is its farthest point from the sun on our sky’s dome. Please deactivate your ad blocker in order to see our subscription offer. Mercury’s orbit is not a perfect circle, so its distance from the sun varies. He began writing online in 2010, offering information in scientific, cultural and practical topics. When it is closest to the sun, it is only 29 million miles (47 million km), but at its farthest, the distance to Mercury is 43 million miles (70 million km). Mercury has a rocky surface and an iron core. The minimum distance from the sun to Mercury is 28.5 million miles. Distance from the sun: About 36 million miles, slightly more than 1/3 as far as the Earth. When Mercury is closest to the sun, it is only 46 million kilometers (29 million miles) distant, but when the planet is rounding the opposite focus of its orbit, it is 70 million kilometers (43 million miles) away from the sun. It speeds around the Sun every 88 days, traveling through space at nearly 29 miles (47 kilometers) per second, faster than any other planet. Mercury's dayside is super-heated by the sun, but at night temperatures drop hundreds of degrees below freezing. The celestial coordinates, magnitude, distances and speed are updated in real time and are computed using high quality data sets provided by the JPL Horizons ephemeris service (see acknowledgements for details). These rocky planets are called ‘Terrestrial Planets’ Unlike a circle, an ellipse doesn't have a center; instead, it has two foci, and in the case of Mercury's orbit, the sun occupies one of them. Mercury is a planet in the solar system and is the closest planet to the sun. It takes 87.96 Earth days for Mercury to revolve around the sun, faster than any other planet, and 58.7 Earth days to … Mercury Distance From Sun And Earth. There was a problem. Unlike Earth, which circles the sun in a nearly circular orbit, Mercury orbits in an ellipse.
