Astronomers must gather information about an exoplanet's atmosphere, often through observing how the planet scatters or absorbs light from its parent star.

The HZ of a star is also sometimes referred to as the «Goldilocks zone,» because this region of circumstellar space, in which an exoplanet can orbit, receives not too little, or too much, but instead just the right amount of radiation from its parent star to allow liquid water to exist on its surface.
