HD 63332 is an F-type main-sequence star in the constellation Lynx. The star has an apparent brightness of 6.02,[2] meaning that it is faintly visible to the naked eye under dark skies.[10] Parallax measurements derive a distance of 29.6 parsecs (97 light-years) to HD 63332.[4] Considering the apparent magnitude and distance from Earth, the star's absolute magnitude is 3.66.[6] No debris disks or exoplanets were detected around it.[11][12]
Characteristics
The star has a spectral classification of F6V,[3] meaning that is a F-type main-sequence star that is currently fusing hydrogen into helium in its core. It has 1.3 times the mass[7] and 1.375 times the radius of the Sun.[4] HD 63332 is 2.67 times more luminous than the Sun, emitting this energy from its photosphere at an effective temperature of 6,298 K, which is around 9% hotter than the Sun.[4] Its age is estimated at 2.1[8] or 3.1 billion years,[6] equivalent to 46% and 68% of the Solar System's age respectively,[lower-alpha 1] and it rotates under its own axis at a velocity of 9 km/s.[9] The B-V color index of the star is 0.496, giving it the yellowish-white color of a late F-type star.[4][13]
HD 63332 is located in the northern hemisphere, 97 light-years from Earth,[4] within the constellation Lynx.[1] It has an apparent magnitude of 6.02, which makes it faintly visible to the naked eye, under dark skies.[10] The absolute magnitude, i.e. its brightness if it was seen at 10 pc (32.6 ly), is 3.66.[6] The star makes part of the thin disk population of the Milky Way,[11] being located at a maximum distance of 60 parsecs (200 ly) from the galactic plane.[6] Its orbit around the galaxy has a low eccentricity of 0.06.[6]
No debris disks have been detected around it as of 2016,[12] and no exoplanets were detected around it as of 2012.[11] It has a 27% possibility of hosting an exoplanet made up of volatiles, lithophiles, siderophiles and iron.[14] The habitable zone is located at a distance of 1.63 astronomical units from the star.[7]
