This star is located around 94 light-years from Sol[1], in the southeastern part of the constellation Puppis, the Stern. Some astronomers have recently classed HIP 40952 as a yellow-orange dwarf star of spectral and luminosity type G5 V, but others once thought that it was a more evolved subgiant[2]. The star appears to a mass (1.00 +/- 0.05) similar to Sol, probably a similar diameter, and about 93 percent of Sol's luminosity. On the other hand, HIP 40952 appears to be 1.4 times as enriched as Sol with elements heavier than hydrogen ("metallicity"), based on its abundance of iron. The star appears to be photometrically stable, with a chromospherically inferred age of around four billion years[2].

The orbit of an Earth-like planet (with liquid water) around HIP 40952 may be centered around 0.97 AUs -- just within the orbital distance of Earth in the Solar System -- with an orbital period of around 350 days.

Known places around HIP 40952

  • HIP 40952 b A giant planet with at least 2.0 times Jupiter's mass. It moves around HIP 40952 at an average distance of 3.32 AUs in a highly circular orbit (e=0.05) that takes about 2,199 +/- 400 days (or around 6.02 years) to complete[3].
