How Far Is Mercury from the Sun?
Mercury is the closest planet to the sun. Mercury's orbit is not a perfect circle, so its distance from the sun varies. The minimum distance from the.and and
Mercury is the closest planet to the sun, and on average, it is 57 million kilometers 35 million miles away. That's less than 40 percent of the distance from Earth to the sun. Mercury's orbit is elliptical, though, and its distance from the sun varies by 24 million kilometers 15 million miles. Unlike Earth, which circles the sun in a nearly circular orbit, Mercury orbits in an ellipse. The eccentricity of Mercury's orbit, which is a measure of how much it differs from a circular orbit, is 0.
Our solar system consists of the sun, eight planets, moons, many dwarf planets or plutoids , an asteroid belt, comets, meteors, and others. The sun is the center of our solar system ; the planets, their moons, a belt of asteroids , comets , and other rocks and gas orbit the sun. Another large body is Pluto , now classified as a dwarf planet or plutoid. A belt of asteroids minor planets made of rock and metal lies between Mars and Jupiter. The largest planet is Jupiter.
The eight planets in our solar system each occupy their own orbits around the Sun. They orbit the star in ellipses, which means their distance to the sun varies depending on where they are in their orbits. So to talk about how far the planets are from the sun is a difficult question, not only because their distances constantly change, but also because the spans are so immense — making it hard for a human to grasp. For this reason, astronomers often use a term called astronomical unit , representing the distance from the Earth to the Sun. The table below first created by Universe Today founder Fraser Cain in shows all the planets and their distance to the Sun, as well as how close these planets get to Earth.
Mercury is famously known for being a scorching hot world. The surface is also airless, in part because any atmosphere it could generate would be blown away by solar wind. Hardly surprising, considering it is the closest planet to our Sun. But just how close is it? However, its orbital eccentricity is also the greatest of any planet in the Solar System. In addition, its orbit is subject to perturbations, ones which were not fully understood until the 20th century. Because of this, Mercury goes through some serious changes during its orbital period.
Mercury is the smallest and innermost planet in the Solar System. Its orbital period around the Sun of It is named after the Roman deity Mercury , the messenger of the gods. This proximity to the Sun means the planet can only be seen near the western horizon after sunset or eastern horizon before sunrise , usually in twilight. At this time, it may appear as a bright star-like object, but is often far more difficult to observe than Venus. The planet telescopically displays the complete range of phases , similar to Venus and the Moon, as it moves in its inner orbit relative to Earth, which recurs over its synodic period of approximately every days. Mercury rotates in a way that is unique in the Solar System.
The smallest planet in our solar system and nearest to the Sun, Mercury is only slightly larger than Earth's Moon. From the surface of Mercury, the Sun would appear more than three times as large as it does when viewed from Earth, and the sunlight would be as much as seven times brighter. Despite its proximity to the Sun, Mercury is not the hottest planet in our solar system — that title belongs to nearby Venus, thanks to its dense atmosphere. But Mercury is the fastest planet, zipping around the Sun every 88 Earth days. Mercury is appropriately named for the swiftest of the ancient Roman gods. Size and Distance. If Earth were the size of a nickel, Mercury would be about as big as a blueberry.

The closest planet to the sun, Mercury takes the least time to orbit the giant star. Its close proximity boosts the world's temperature, and makes it difficult to hold on to its atmosphere. But just how close is close?
