Goldilocks Zones and Stars
This infographic illustrates the "Goldilocks zone," or habitable zone, around different types of stars. It shows where liquid water could exist on a planet's surface. For M dwarf stars, which are common and long-lived, this zone is small and close to the star. Our Sun, a G star, has a larger habitable zone farther out.
