What causes craters on Mars?
Impact craters are caused when a bolide collides with a planet. The Martian surface contains thousands of impact craters because, unlike Earth, Mars has a stable crust, low erosion rate, and no active sources of lava. So, impact craters on Mars are not obliterated as they are on Earth.
How old are Mars craters?
Abstract. The rate of crater formation on Mars is calculated to be about 25 times higher than that on the Moon. The crater density observed by Mariner IV points to an age only one-sixth that of the lunar maria, or 300 to 800 million years.

How many impact craters are on Mars?
43,000 impact craters
While only about 120 impact craters have been identified on Earth, scientists estimate that on the surface of Mars, there are more than 43,000 impact craters with diameters greater than 5 kilometers (3 miles), and probably over a quarter of a million impact craters that are similar in size to Meteor Crater.Dhuʻl-H. 1, 1441 AH

What is the largest impact crater on Mars?
Mars: Hellas Planitia. The largest visible impact crater in the Solar System is Hellas Planitia on Mars, a giant depression with a floor over seven kilometres (4.3 miles) below the Martian surface .
How are the craters on Mars caused?
Nested Craters on Mars, 40.104° N, 125.005° E. These nested craters are probably caused by changes in the strength of the target material . This usually happens when a weaker material overlies a stronger material. In the absence of atmosphere, the impact process begins when the impactor first touches the target surface.
How many craters does Mars have?
The surface of Mars is pocked by more than 635,000 impact craters at least 0.6 miles (1 kilometer) wide, a new study reports. The new Martian crater atlas is the largest single database ever compiled of impacts on a planet or moon in our solar system, researchers said.
