The CARMENES survey (Calar Alto high-Resolution search for M-dwarfs with Exoearths with Near-infrared and optical Échelle Spectrographs) is a project to examine approximately 300 M-dwarf stars for signs of exoplanets with the CARMENES instrument on the Spanish Calar Alto's 3.5m telescope. Operating since 2016, it aims to find Earth-sized exoplanets around 2 (

Earth masses An Earth mass (denoted as ''M''🜨, ''M''♁ or ''M''E, where 🜨 and ♁ are the astronomical symbols for Earth), is a unit of mass equal to the mass of the planet Earth. The current best estimate for the mass of Earth is , with a relative ...

Doppler spectroscopy Doppler spectroscopy (also known as the radial-velocity method, or colloquially, the wobble method) is an indirect method for finding extrasolar planets and brown dwarfs from radial-velocity measurements via observation of Doppler shifts in ...

(also called the radial velocity method). More than 20 exoplanets have been found through CARMENES, among them Teegarden b, considered one of the most potentially habitable exoplanets. Another potentially habitable planet found is

Gliese 357 d Gliese 357 d is an exoplanet, considered to be a "Super-Earth" within the circumstellar habitable zone of its parent star. The planet orbits Gliese 357, 31 light-years from the Solar System, The system is part of the Hydra constellation. The ...
