Size Does Matter!


When looking for planets with life, it is a good idea to keep the size of the planets in mind. Small planets, no matter how small, can still host life. Though super-large planets will have a less likely chance of having life on them, they will still be more restricted on the types if life. The larger a body, the stronger its gravitational pull is. Life forms may be crushed by gravity. Life forms can exist with little gravity. Microbes can even exist without gravity! So size does matter.
