Distance of Things
The Earth is approximately 147 million km from the Sun. It is a tiny thing. You can fit 1,300 Earths into Jupiter. Jupiter, you think, must be huge.
The diameter of Jupiter is 140 thousand km. This means you can line up 1050 Jupiters back to back between the Earth and the Sun. As big as Jupiter is, it is still less than 1% of the distance from the Sun to the Earth.
The distance from the Sun to Jupiter is 747 million km. The size of Jupiter is less than 0.02% its distance from the Sun.
If you draw a scale model of the solar system on a piece of A4 paper and put the Sun in one corner and Jupiter at the opposite corner, Jupiter will be 0.003 inches wide – a tiny dot no bigger than the thickness of a human hair.
Space – it is really empty.
