Uranus is about 1.3 times of the size of Neptune, and its total diameter of 50,724 km is more than four times larger than Venus.

The smallest planet in the solar system is Mercury, which only has a diameter of 4,780 km. Mars is the second smallest, with a diameter of 6,780 kilometers. Before it was reclassified as a dwarf planet, Pluto used to be the smallest planet in the solar system, with a diameter of only 2,800 km. There are actually two moons in the solar system that are larger than Mercury. Both Saturn's moon Titan and Jupiter's moon Ganymeade are slightly larger than Mercury.
