Venetia Katharine Douglas Burney was an English accountant and teacher. She is remembered as the first person to suggest the name Pluto for the dwarf planet discovered by Clyde Tombaugh in 1930. At the time, she was 11 years old.

Pluto is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most-massive known object to directly orbit the Sun. It is the largest known trans-Neptunian object by volume, by a small margin, but is less massive than Eris. Like other Kuiper belt objects, Pluto is made primarily of ice and rock and is much smaller than the inner planets. Pluto has roughly one-sixth the mass of Earth's moon, and one-third its volume.

Sputnik Planitia is covered with churning nitrogen ice "cells" that are geologically young and turning over due to convection.
