Which is the smallest planet in the solar system?
Mercury
The solar system has eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Since Pluto was reclassified as a dwarf planet in 2006, the smallest of the eight is Mercury.
Mercury has a diameter of about 4,880 km, which is smaller than every other planet and even smaller than Jupiter’s moon Ganymede and Saturn’s moon Titan. It is also the planet closest to the Sun.
The Sun is a star, not a planet, and is by far the largest body in the solar system. Earth (about 12,742 km across) and Venus (about 12,104 km across) are almost equal in size and are much larger than Mercury.
