Meteorite Distribution Map of Vesta
This map shows the distribution of HED meteorites on the surface of Vesta. HED meteorites are a type of achondrites, stony meteorites that do not contain any chondrules. Here, each color represents a different mineral: green is howardite, blue is eucrite, and red is diogenite. Areas where more than one mineral is present are either yellow for diogenitic howardite or cyan for euritic howardite. Rocks containing howardite are the most abundant on Vesta.
The map shows that the two hemispheres have different mineral distributions: the northern hemisphere is more eucritic rich while the southern hemisphere is more diogenitic rich. For reference, two craters and two basins are marked.
