Q1:How much bigger is the Sun compared to the Moon?

[Answer]

The Sun is about a hundred times as big across as the Earth. The Moon, on the other hand, is only a quarter of the Earth's size.

From the Earth, the Moon and Sun look about the same size. This is because the Moon is so much closer to us.

Like so much in the sky, this is an optical illusion.
