# Class S00 Yellow Star

    Class S00 stars are just like our Sun, and if you're looking for planets supporting life and breathable atmosphere, you should definitely take a look around class S00 stars. In fact, such planets are possible even around other stars, for example live planets have also been discovered around a few class S03 stars. A well known, catalogued system is Miracle. However, this is rather rare, so it's best to look for life around S00 stars.

# Class S01 Blue Giant Star

    Class S01 stars are huge, and often support large solar-systems. Some Blue Giants have anything up to twenty or thirty planets. However, travelling within Class S01 systems often takes a long time, as the orbits of the planets tend to be spread over a very wide area.

# Class S02 White Dwarf Star

    These stars are the remains of class S00 stars that have exploded as Red Giants, then shrunk down to only a highly dense core. These rarely have any planets, as any orbital objects were usually burnt up when the star exploded. If you do find any surviving planets, they will most likely be a long way from the star. Gas giants and other massive bodies may also have survived.
