The distance to this star is 116 light years from the Sun based on parallax, but it is drifting closer with a radial velocity of −12 km/s.
[3] It has been identified as a solar twin by Datson et al. (2012), which means its physical properties are very similar to the Sun.
The star is estimated to be 1.6[4] billion years old and is spinning with a projected rotational velocity of 4.2 km/s.
[3] It is radiating 1.16 times the luminosity of the Sun from its photosphere at an effective temperature of 5,869 K.[4] The star is currently known to have one planet, designated HD 142415 b.
The authors chose to pin the eccentricity value to 0.5, although solutions in the range 0.2–0.8 would be equally plausible.
