3 obvious star mission destinations

Alpha Centauri is the star system closest to our Solar System, but there are also other interesting stars in Earth’s neighbourhood. Around several of those, planets are orbiting, which could include life, according to scientists.

NEIGHBOURING STAR COULD HAVE TWO HABITABLE WORLDS

Distance: 112 trillion km Five planets may orbit Tau Ceti, two of which, Tau Ceti e and f, are located in the habitable zone. Tau Ceti is much like the Sun, and it could be the obvious destination of the next star mission after Alpha Centauri.

TRIPLE SYSTEM HOME TO "SUPER-EARTH"

Distance: 2.23 quadrillion km Gliese 667 has three small stars – Gliese A, B, and C. At least two exoplanets orbit Gliese C in the habitable zone. One of them is known as a “super-Earth”, as it is a rocky world larger than Earth.
