Mercury speeds around the sun every 88 days, traveling through space at nearly 50 km (31 miles) per second, faster than any other planet. One Mercury solar day (one day-night cycle) equals 175.97 Earth days.

Mercury's outer shell, comparable to Earth's outer shell (called the mantle and crust), is only about 400 km (250 miles) thick. The first spacecraft to visit Mercury was Mariner 10, which imaged about 45 percent of the surface.

Learning About Mercury’s Orbit. Mercury has a very eccentric orbit. At some points, it is 29 million miles from the sun and at others, it is 43 million miles away. Considering the orbit of all of the planets, Mercury’s is the shortest in terms of its orbit around the sun. Compared to all planets, Mercury has the most elliptical of all of the orbits.

Mercury has the most eccentric orbit of all the planets; its eccentricity is 0.21 with its distance from the Sun ranging from 46,000,000 to 70,000,000 km (29,000,000 to 43,000,000 mi). It takes 87.969 Earth days to complete an orbit.

Distances Between the Planets The distances between each planet in our solar system will vary depending on each orbit. No planet has a perfectly circular orbit around the sun and therefore the distance between each planet can take on two very extreme numbers. For example, the distance between Mercury and Earth can range from 77 million kilometres at their closest point, to 222 million kilometres at their farthest. For this reason, it is easiest to look at the average distance between planets as opposed to a specific distance at any point in time; however we have also included minimum and maximum distances.

Mercury is the second densest planet after Earth, with a large metallic core having a radius of about 2,000 km (1,240 miles), about 80 percent of the planet's radius. In 2007, researchers used ground-based radars to study the core, and found evidence that it is partly molten (liquid).

Facts About Mercury. If you were standing on Mercury when it was in the part of its orbit that puts it closest to the sun, the sun would appear three times larger compared to the size it seems on Earth. There is no atmosphere on this planet that is able to retain heat.

Planet Distance Matrix. Below is a matrix of the eight planets in our solar system and their respective distances from each other. Each distance is calculated as an average and converted into astronomical units (AU) where 1 AU = the distance between the Sun and Earth = 149,598,000 kilometres. This chart is based on averages and the distances from one planet to another have been calculated by the difference in their mean distance from the sun.

Mercury: In Depth. The battered surface of Mercury. Image Credit: NASA/USGS/JHUAPL. Mercury's eccentric orbit takes the small planet as close as 47 million km (29 million miles) and as far as 70 million km (43 million miles) from the sun. If one could stand on the scorching surface of Mercury when it is at its closest point to the sun, the sun would appear more than three times as large as it does when viewed from Earth.

Mercury is the first planet from the sun. Earth is the third. The distance between Mercury and Earth is approximately 48 million miles. However, this can change depending on where the planets are in their individual orbits. The maximum distance apart is 137 million miles. They are in a constant flux and the maximum distance is when both are on opposite sides of the sun. Learning About Mercury’s Orbit
