Quick aside:
The distance between the Earth and the nearest star, the Sun, is 1 AU.
This is around 150,000,000 kilometers (93,000,000 miles).
The next nearest star, Proxima Centari, is 870,000 times farther away (1.3 parsec).
Analogy:
If the Sun/Earth is across the classrom, then the Sun/Proxima Centauri
is from Flagstaff to London.
Even the closest stars are far, far away.
