Question: Do stars ever move?

Keywords:

  1. All the time! It’s just that from our perspective they don’t seem to move much from day to day (or year to year for that matter). They are all orbiting the centre of the galaxy. A famous astronomer called Edmund Halley noticed about 300 years ago that one constellation described by the Greeks was a bit different than when they recorded it 1600 years earlier

  2. Great question!

    Stars are constantly moving through space, but most of the time we can’t see it. The closer the stars are to Earth, the faster they appear to move. This is actually one of the ways we find very faint nearby stars, by looking for fast moving stars in the sky.

    Another reason that stars move is that they might orbit another star close by. Alpha Centauri is the third brightest star in the sky and is the nearest star system to us. If you look at it through binoculars you can see two stars orbiting each other every 80 years. If you looked in 20 years you would only see one star as they would be too close together to distinguish!
