Basic Properties of Stars
... To give you an idea of the distances involved: the Sun is about 1 million miles in diameter. In other words, walking once around the Sun is equivalent to walking about 100 times around the Earth! But if you shrink the Sun into the size a ball bearing (about 1 cm in diameter) then, • The Earth is a d ...
