Mercury doesn't have many geographically distinct features but it does have a feature called the Caloris Basin. The Caloris Basin is one of the largest meteor impact basins in the Solar System. It measures at about 1,550 kilometers or 960 miles in diameter. Since the Caloris Basin is the largest feature on Mercury it is also it's longest.
The most distinctive and longest feature on the planet Mercury is the Caloris Basin. It is multi ringed and covers about 840 miles in diameter.
