galaxy

A galaxy is a group of stars, along with everything that’s orbiting them.  On Earth, our Galaxy is called the Milky Way.  It’s a ball of stars, with two arms of stars spiralling from it.  It has about 191 000 000 000 stars.  It’s about 950 000 000 000 000 000 metres across, and the central bulge is about 150 000 000 000 000 000 metres deep.

Saying ‘group’ and ‘ball’ of stars may make them sound close together, but they’re not.  The nearest sun to Sol is Proxima Centauri, which is 40 000 000 000 000 metres away.  That is close, if you compare it with the distance between our galaxy and the nearest one – 850 000 000 000 000 000 metres.  Victor told me those numbers, and I believe him.

I discussed galaxies with Hais before we visited Snale.  See Report L.
