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.
Borealis Basin is significantly larger than Hellas Crater. Borealis Basin, located in the northern hemisphere of Mars, spans approximately 8,500 kilometers (5,300 miles) in diameter, making it one of the largest impact features in the solar system. In contrast, Hellas Crater, situated in the southern hemisphere, has a diameter of about 2,300 kilometers (1,400 miles). Therefore, Borealis Basin is much larger than Hellas Crater.
