Proxima Centauri, Closest Star to Earth, Has Exoplanet Where Temperature and Water Might Make It Habitable
“One of the main features that distinguishes this planet from Earth is that
the light from its star is mostly in the near infra-red. These frequencies of light interact much more strongly with water vapour and carbon dioxide in the atmosphere, which affects the climate that emerges in our model [of Proxima Centauri and exoplanet.]”

The closest star system to the Earth is the famous Alpha Centauri group. Located in the constellation of Centaurus (The Centaur), at a distance of 4.3 light-years, this system is made up of the binary formed by the stars Alpha Centauri A and Alpha Centauri B, plus the faint red dwarf Alpha Centauri C, also known as Proxima Centauri. This NASA/ESA Hubble Space Telescope has given us this stunning view of the bright Alpha Centauri A (on the left) and Alpha Centauri B (on the right).
