When a low-mass star like the Sun burns up all of its fuel, it dramatically sheds its outer layers until it becomes a so-called red giant. These outer layers spread through the star’s immediate vicinity, threatening to completely annihilate any planet in their way. The star itself will then shrink down and become a super-dense white dwarf star while it slowly loses heat over trillions of years. Any planet caught in this cosmic cataclysm would be extremely lucky to survive but there are some planets in particular, which are best suited to weather the storm.
