What Makes A Planet Habitable?

There are many planets in the universe, but very few of them have qualities to support life Taking one celestial body at a time and determining whether it supports life would be slow and inefficient. So, astronomers look for certain pointers in a celestial body to determine habitability.

Here are the key factors that make the planet habitable:
1. It has to be a comfortable distance away from a star (Habitable Zone)
2. The stars around it have to be ‘stable’
3. It should not have a very low mass
4. It must rotate on its axis and revolve
5. It should have a molten core
6. It should hold an atmosphere
