The story
A super-Earth by calculation: mass at least 3.7 Earths, circling its star in 28 days. The system has three stars, so two more orange suns show in the planet’s sky; a world with several sunrises.
Habitability is debated: the star’s flares and the planet’s high gravity are hard. But it may still receive enough heat for liquid water.
Missions
- HARPS radial-velocity measurements (2011): discovery
- An interstellar destination; no mission yet
Colony note
High gravity (~1.5 g); cryo sleep and a shield are needed.
What probes bring back
- About 23.6 light-years; mass ≥ 3.7 Earths (catalogue). In a triple-star system.
- In the habitable zone; two more orange stars show in its sky.
