Star

Apparent magnitude: 1.84 mag
Parallax: 2.03 mas → about 1,606.7 light-years away
Spectral type: F8Ia
Right ascension: 107.0979°
Declination: -26.3932°
Designation: HR 2693
Bayer designation: δ CMa
HIP number: 34444
IAU name adopted: 2016-07-20
Name language: Arabic
Name origin (IAU): From the Arabic name al-wazn, for one of a pair of stars, the other one being hadari. Arabic authors ventured to identify these stars as α/β Cen or α/β Col, but exactly what two stars were originally intended, and the significance of their names, is unknown. As a common noun in Arabic, al-wazn means "the weight". "Wezen" was arbitrarily applied to δ CMa in recent times.

Constellation

Light from this object takes about 1,607 years to reach Earth — the light you see tonight left around AD 419 (official distance ÷ speed of light).
At magnitude 1.8 it is bright enough for the naked eye (limit about 6) — look from somewhere dark.
Declination -26.4° — it rises above the horizon in Seoul (37.6° N), so it is visible from Korea in the right season.
