The smallest number of distinct points that can define a plane would be 3 points. Below this value, you cannot create a plane, you can only create a line or a point. A plane that has three point is called a triangle. Hope this helps. Have a nice day.
        
             
        
        
        
The lunar eclipse happens when the Moon goes through the Earth's shadow. Earth dependably has a shadow, which is made by the Sun. On those uncommon events when the Moon, Earth and the Sun are altogether arranged perfectly, the Moon goes through this shadow.This would happen each full moon if the Moon circled around the Earth in an indistinguishable plane from the Earth circles around the Sun.
