The star is too faint to be viewed with the naked eye, having an apparent visual magnitude of 7.50.
It is radiating 1.8 times the luminosity of the Sun from its photosphere at an effective temperature of 5,917 K.[4] The star is spinning slowly with a projected rotational velocity of 2.4 km/s.
[5] A long period planet was discovered in 2006 based on observations made at the W. M. Keck Observatory in Hawaii.
However because the observations covered less than one complete orbit there were only weak constraints on the period and mass.
[5] The first reliable orbit for HD 24040b was obtained by astronomers at Haute-Provence Observatory in 2012 who combined the keck measurements with ones from the SOPHIE and ELODIE spectrographs.
