You might think that Mars is a near-twin of Earth, but it has a diameter of about half the Earth, measuring only 6,800 km across.
Neptune.

Planets from smallest to largest: Mercury Mars Venus Earth Neptune Uranus Saturn Jupiter Mercury is the smallest planet Jupiter is the largest planet
The smallest planet is MercuryMercury
If ranking it only according to size, Uranus would be the third largest planet (after Jupiter and Saturn). If ranking it according to mass, it would be the 5th largest planet (after Jupiter, Saturn, and Neptune).
it is the smallest planet
