Largest crater on Pluto

Sputnik Planum, located mostly in Pluto’s northern hemisphere, measures around 1,050 by 800 km. Its bright surface is dominated by nitrogen ice and is the site of active nitrogen glaciation. The lack of impact craters indicate the surface of Sputnik Planum is less than 10 million years old. These icy plains are now believed to occupy a giant ancient impact basin, which has been filled with volatile ices. The largest "classical" impact crater, which has not undergone extensive resurfacing on Pluto is Venetia Burney.

The Sputnik Planum impact basin was caused by an impact of a body with an estimated size of 10 km across, i.e., an object the size of Manhattan Island.

The largest "classical" impact crater, which has not undergone extensive resurfacing on Pluto is Venetia Burney – previously the largest crater on Pluto overall.
