The New Horizons team located more than 1,000 craters on this map of Pluto. Scientists count the number of impact craters to determine the age of a surface.

Older regions generally have more impact craters. Pluto’s oldest regions are about 4 billion years old. Its youngest areas may have formed within the past 10 million years.
