Some stars are so close that we can actually see their angles move with time due to the relative motion between them and the <Sun>, e.g. <Proxima Centauri>!

Some notable ones:
* <Proxima Centauri>, the nearest one, at 4 <ly>. It is part of the <Alpha Centauri> <star system>, which contains two other stars at very similar distances as well, and their relative distances to earth will change positions in a few tens of thousands of years.
* <Sirius>, the brightest star in the sky at 9 <ly>
