More about solar system

Hi everyone. I am going to convey some some facts about solar system. We live on the planet Earth. The light is so fast that it takes only eight minutes for the light to reach the earth. Many probes are sent to other planets to learn about it. Eg pathfinder. Our solar system is surrounded by a belt of asteroid called Kulper belt and it is also surrounded by Oort cloud. Highest volcano is located on Mars. It is called Olympus Mons. It is three times as high as Mount Everest.

The type and duration of a lunar eclipse depends on the position of moon in the orbit. This eclipse can be partial or total.
