It was officially named Lusitânia on 17 December 2019, after the IAU100 press conference in Paris by the IAU (International Astronomical Union).
The system is located at a distance of 114 light-years from the Sun based on parallax measurements,[1] but is drifting closer with a radial velocity of −5 km/s.
[5] It shows a high proper motion, traversing the celestial sphere at an angular rate of 0.188 arcsec yr−1.
[9] The measured atmospheric properties match a metal-rich late G- or early K-type dwarf star.
[6] It is radiating 61%[6] of the Sun's luminosity from its photosphere at an effective temperature of 5,342 K.[6] HD 45652 is spinning with a projected rotational velocity of 3.5 km/s.
