Star

Apparent magnitude: 2.21 mag
Parallax: 5.99 mas → about 544.5 light-years away
Spectral type: K4Ib-II
Right ascension: 136.999°
Declination: -43.4326°
Designation: HR 3634
Bayer designation: λ Vel
HIP number: 44816
IAU name adopted: 2016-08-21
Name language: Arabic
Name origin (IAU): Applied in recent times and representing an abbreviation of any of several composite pre-Islamic Arabian names (for example suhail al-wazn, suhail al-muhlif) that Arabic authors variously attributed to brighter stars in the region of suhail. A Vel was among these brighter stars. Some of the composite names may have been authentic pre-Islamic Arabian names for far-southern stars, with their true identities unknown to the more northern Arabs, while others of them were surely the creations of pre-Islamic Arabian poets.

Constellation

Light from this object takes about 545 years to reach Earth — the light you see tonight left around AD 1481 (official distance ÷ speed of light).
At magnitude 2.2 it is bright enough for the naked eye (limit about 6) — look from somewhere dark.
Declination -43.4° — it rises above the horizon in Seoul (37.6° N), so it is visible from Korea in the right season.
