# Class S03 Red Giant Star These are class S00 stars that have exploded, and now cover a massive area. They have usually consumed all their planets as they have expanded, so it is rare to find objects orbiting these. However, it is not impossible; the Miracle system is a well known class S03 system that nevertheless harbours a planet with an oxygen based atmosphere and water, IE one that could support life. However, the planet's discoverers found it to be cold and frozen, with no surface life. They were so disappointed that they named the planet "Piece Of Ice". # Class S04 Orange Giant Star These are just very large stars, otherwise similar to class S00 stars. However, you will rarely find life-bearing planets around these, as the planets' orbits tend towards being very distant, making them cold and inhospitable.
