<Ciro Santilli> likes to learn astronomy a bit like he learns geography: go down some lists of "stuff that seems most relevant in some criteria to us!", possibly at different size scales e.g.:
* <stars nearest to the Sun>
* <brightest natural objects in the sky>
* <galaxies nearest the Milky Way>
* <black holes nearest to the Sun>

This is quite close! But as mentioned at: <stars nearest to the Sun>, there are several others nearby. Notably <Sirius> at 9 <ly>, the brightest star in the sky as of 2020.

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>
