List of terrestrial exoplanet candidates for atmosphere detection

From Wikipedia, the free encyclopedia

The rocky exoplanets are thought to be abundant in the Milky Way, however their existence of atmosphere and their atmospheric composition are generally unknown.[1] The existence of a stable atmosphere depends on several factors including total amount of radiation receive (which is related to the spectral type of host star), the surface gravity (related to mass and radius) and the orbital period.[2]

As of 2024, 55 Cancri e is the first and the only terrestrial exoplanet with verified atmospheric detection. Its atmosphere might have been re-generated by the magma ocean and is composed of either carbon monoxide (CO) or carbon dioxide (CO2).[3]

Perspective

To be included in the following list, an exoplanet must:

  • Be terrestrial or nearly terrestrial
  • Transit the host star from the Earth's view
  • Have been studied using the transmission spectroscopy and have published claim(s) of atmospheric detection, whether confirmed or not.

Note that mass values prefixed with "~" have not been measured, but are estimated from the mass-radius relationship.
