HD 23127 is a star in the Reticulum constellation. At the distance of 290.7 ly, it is not visible to the naked eye, but it is visible with a good pair of binoculars.

Star

HD 23127 is a hydrogen-fusing sun-like star with spectrum G2V. The star is more massive than our Sun at 1.13 solar mass. The star is also more metal-rich, meaning it contains two times more metals [Fe/H] than our Sun. The age of the star is older than the local star at 7 billion years old, more than half-way through its life.

Planetary system

On Friday, February 9, 2007, a 1214 day period jovian planet was found by using the wobble method by O’Toole in Australia. It has minimum mass 37% greater than Jupiter and orbits in 44% eccentricity. The distance from the star ranges from 1.28 to 3.30 astronomical units with the average distance 2.29 astronomical units.
