The small planet in the solar system

What is the smallest planet in our Solar System?

Mercury is the smallest planet in our solar system. Mercury is a little more than one-third the width of Earth, and has an equatorial diameter of about 3,032 miles (4,880 kilometers). Mercury is the closest planet to the Sun, orbiting at an average distance of 36 million miles (58 million kilometers).

Is Mercury the smallest planet in the Solar System?

Mercury may be the smallest planet in the solar system, yet it is actually one of the densest planets in the solar system. In fact, the only planet denser than Mercury is Earth, which makes Mercury the second densest planet in the solar system. However, if we measure density relative to size, then Mercury is actually denser than Earth.

What is the smallest dwarf planet?

Ceres is the smallest dwarf planet with an equatorial diameter of about 599 miles (about 964 kilometers). Ceres is about 1/13 the width of Earth.

Which planet is closest to the Sun?

Mercury is the closest planet to the Sun, orbiting at an average distance of 36 million miles (58 million kilometers). Mercury is 57 million miles closer to the Sun than Earth. Pluto is the largest dwarf planet in our solar system, just slightly larger than Eris, at number two.

What is the smallest exoplanet?

Unsurprisingly, very small exoplanets, or planets orbiting other stars, are extremely hard to spot. But of the ones scientists have found, the smallest is Kepler 37-b. Discovered in 2013 by scientists using data from the Kepler space telescope, it is smaller than Mercury and about the same size as Earth's m oon.

What is the largest planet in the Solar System?

Hold Mercury in your hand: Sky & Telescope offers a 12-inch Mercury globe based on imagery from NASA's Messenger spacecraft. The largest planet in our solar system by far is Jupiter, which beats out all the other planets in both mass and volume.
