- HD_221287_b abstract "HD 221287 b is an exoplanet approximately 173 light years away in the constellation of Tucana. This planet has mass >3.12 MJ (>992 M⊕) and orbits in a habitable zone at 1.25 AUs (6.06 μpc) from the star, taking 1.25 years to orbit at 29.9 km/s around the star. Naef discovered this planet in early 2007 by using HARPS spectrograph located in Chile.Based on a probable 10−4 fraction of the planet mass as a satellite, the planet can have a Mars-sized moon with habitable surface. On the other hand, this mass can be distributed into many small satellites as well.".
