The Hellas Basin is a large impact crater located in the Southern Hemisphere of Mars, measuring about 2,300 kilometers (1,400 miles) in diameter and reaching depths of up to 8 kilometers (5 miles). It is one of the largest and oldest impact features on the planet, believed to have formed around 4 billion years ago. The basin's floor is characterized by a mix of flat plains and rugged terrain, and it contains evidence of past water activity, making it a significant area for studying Mars' geological history and potential for past life.
