Mars, with a diameter 0.53226 times that of the Earth.
Planet Mercury is the smallest planet and is less than half the diameter of the earth. It surface is scared with numerous impact craters and and thus resembles earth's moon
The Earth has a diameter of 12,756 km. A planet that has a diameter that's around one-half that of Earth's would be Mars, which has a diameter of 6,792 km.
Three planets have diameters smaller than Earth's: Mercury, Venus, and Mars.
Mercury, Venus and Mars all have diameters smaller than that of Earth, as well as all the dwarf planets.
Mercury
Uranus is third largest. Diameter = 51115km, about 8 times that of Earths diameter.
Mars.
Venus is closest to the Earths size and mass - often referred to as Earths sister or twin planet. Venus' Mass is around 82% of Earths, while its diameter is a little smaller than Earths at around 95% of Earths diameter.
