Pluto
Pluto as observed by the New Horizons spacecraft, July 13, 2015.
Pluto is significantly smaller than Earth’s Moon. With a diameter of 2,370 km (1,473 miles), Pluto is only about two-thirds the size of the Moon, which has a diameter of 3,474 km (2,159 miles).12
Because of its diminutive size, Pluto is more comparable to the large icy moons found orbiting the outer planets than it is to any of the major planets in our solar system.12
