The story
Announced in 2015 as ‘Earth’s cousin’: in the habitable zone of a star much like the Sun, with a 385-day year. Its star is 6 billion years old, 1.5 billion years older than the Sun. How rocky it is remains unknown; with a radius of 1.6 Earths it may be a small Neptune.
The distance is so great that even a ray of light takes 1,400 years. In the game this is the farthest ‘Earth-like’ candidate humanity can reach.
Missions
- Kepler space telescope (2015): discovery
- Future: new-generation telescopes and interstellar concept missions
Colony note
A Sun-like star, a year like Earth’s: but gravity may be heavy. Cryo sleep, a shield and a very long voyage.
What probes bring back
- About 1,400 light-years; ‘Earth’s cousin’: a Sun-like star and a 385-day year (2015).
- Radius ≈ 1.6 Earths: rocky or gaseous, uncertain.
