What Makes A Planet Habitable?
ScienceABC II・3 minutes read
Astronomers assess a planet's habitability based on factors like its distance from a star, mass, atmosphere, and meeting specific criteria, focusing on planets within the Habitable Zone (HZ) for potential life due to liquid water on the surface and stable nearby stars to prevent extreme conditions.
Insights
- Astronomers assess a planet's habitability based on factors like distance from its star, mass, rotation, atmosphere, and more, to determine its potential to support life.
- Planets in the Habitable Zone (HZ) have the ability to sustain liquid water on their surface, with stable nearby stars playing a critical role in maintaining conditions suitable for life.

Factors for Life on Planets in HZ
- Astronomers determine a planet's potential to support life by considering various factors such as its distance from a star, the stability of surrounding stars, mass, rotation, molten core, atmosphere, and meeting geochemical, astrophysical, astrological, and geophysical criteria.
- Planets within the Habitable Zone (HZ) around a star have the potential for life due to the ability to maintain liquid water on the surface, while stable luminosity of nearby stars is crucial to prevent extreme conditions that could hinder habitability.
