what is a solar eclipse?
a solar eclipse is a natural event that takes place on earth when the moon moves in its orbit between earth and the sun (this is also known as occulation). it happens at a new moon when the sun and moon are in conjunction with eachother. if the moon was only slightly closer to earth and orbited in the same plane and its orbit was circular, we would see eclipses each month. the lunar orbit is elleptical and tilted with respects to earths orbit, so we can see upto 5 eclipses a year. depending on the geometery of the sun, moon and earth, the sun can be fully blocked or partially blocked. during an eclipse the moons shadow (which is divided into 2 two parts:the dark umbra and the lighter penumbra) moves across earths surface.
