What Makes A Planet Habitable?

Out of the countless planets in the universe, only a tiny fraction could potentially support life. So what exactly makes a planet habitable, and how do astronomers narrow down the search? In this video, we explain the key factors that determine whether a planet can sustain life, including its distance from a star, the stability of nearby stars, its mass and gravity, rotational properties, magnetic field, and the crucial role of an atmosphere.
