It has always been a wonder to me how the Sun and Moon are almost exactly the same size when viewed from Earth. What are the chances?
The diameter of the Sun is around 400 times bigger than the Moon, but it is 400 times further away from us so they appear similar in size. Whether it is a coincidence or not, who knows.
The Earth is an amazing place and we tend to focus a great deal on ourselves. But all you have to do is look up at the stars on a clear night to realise how insignificant we really are. This simple act puts everything back into perspective, as well as being one one of the most awe inspiring shows from Earth. And it is free!
