Where is the largest known impact basin in the Solar System?

Quick Answer

One of the largest known impact basins in the Solar System is Caloris on Mercury. It is about 1,550 km across.

The Full Story

Caloris Planitia on Mercury is among the biggest impact basins in the Solar System and is often described as the largest on Mercury itself. It was formed by a massive ancient impact that reshaped a huge part of the planet’s crust. The event also caused landforms on the opposite side of Mercury, likely from seismic waves converging there. MESSENGER data helped reveal its complex geology and volcanic history.
