ELi5: Do all stars have habitable zones?

626 views

So I know that stars have habitable zones where, when you get to a certain distance, a planet within this zone is in a comfortable position to host life. But do all stars have this habitable zone or does the certain nature of stars get rid of the possibility of a habitable zone?

All stars have a [habitable zone](https://en.wikipedia.org/wiki/Circumstellar_habitable_zone). It is based on the temperature of the star, since the star is the energy source for the planet. [This graphic](https://upload.wikimedia.org/wikipedia/commons/f/f0/Diagram_of_different_habitable_zone_regions_by_Chester_Harman.jpg) shows where Earth, Venus, and Mars are in the habitable zone, as well as how the zone changes for different temperatures. Some exoplanets are also included.
