Scientists using a new technique to image exoplanets in the mid-infrared may have just found a super-Earth-sized exoplanet around Alpha Centauri, the nearest star system to us. Whats more the planet is orbiting in its star’s habitable zone.
At just over 4.22 light years from Earth, Alpha Centauri shines in the sky as a single star and the third-brightest star visible from our world. But, in reality Alpha Centauri is a triple star system consisting of two sun-like stars, Alpha Cen A & B, and a smaller red dwarf star called Proxima Centauri.
Proxima Centauri is already famous for harbouring a a rocky planet – Proxima b – not much bigger than the Earth; a significant finding uncovered by scientists a few years ago, after the exoplanet was spotted whizzing around the red dwarf in just 11 days.
