Total eclipse

It is by pure coincidence that we exist on a planet and in a time when our star is covered exactly during a total eclipse. The Sun's distance from Earth is 400 times the Moon distance, and the Sun's diameter is 400 times the diameter of the Moon. Because of this coincidence, we are experiencing a total eclipse. No other known planet has total eclipses and at some point, in the future, they won't occur on Earth either.
