SOLAR SYSTEM

Detailed explanation-1: -Craters are windows into the past, present and future. Lessons from impact craters have been essential to developing our understanding of the past and present of the Solar System. Scientists study craters on planets, asteroids and moons to learn about the geological history of those bodies.

Detailed explanation-2: -The surfaces of asteroids and the rocky, ice covered moons of the outer gas planets are cratered as well. The craters left by impacting objects can reveal information about the age of a planet’s surface and the nature and composition of the planet’s surface at the time the crater was formed.

Detailed explanation-3: -Planets and moons across our solar system bear the scars of collisions. Impact craters form on their surfaces when another object, such as a dust particle, rock, asteroid, or comet smashes into them.

Detailed explanation-4: -Craters are formed when objects from space crash onto a planet’s surface. The impact blasts a hole or impression where the object lands. The size of the crater depends upon the size of the object that collides into the planet. Craters can be seen on all the rocky planets, including Earth.

Detailed explanation-5: -Impact craters provide insights into the age and geology of a planet’s surface. 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.
