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
