HIP 11915 is a G-type main-sequence star located about 170 light-years from Earth in the constellation Cetus.
[9] HIP 11915 is a G-type main sequence star that is just about the same mass of and likely 101% the radius of the Sun.
The system contains a gas giant, HIP 11915 b, with a mass and orbit very similar to that of Jupiter, located at approximately the same distance from its star.
[13] The radial velocity data also indicates that there is no large gas giant in this system with an orbital period of less than 1000 days.
[14][15] According to Jorge Meléndez, who led the University of São Paulo, Brazil team that discovered HIP 11915 b, "the quest for an Earth 2.0, and for a complete Solar System 2.0, is one of the most exciting endeavors in astronomy".
