Star

Apparent magnitude: 4.31 mag
Parallax: 28.83 mas → about 113.1 light-years away
Spectral type: F0V
Right ascension: 231.1231°
Declination: 37.377°
Bayer designation: μ Boo
HIP number: 75411
IAU name adopted: 2016-08-21
Name language: Latin
Name origin (IAU): The formation of this name begins with one of the words used by Ptolemy to describe this star in the Almagest: κολλόροβον, "club", rarely used as "sphepherd's staff". This word was transliterated into Arabic as qulurubus, and hence into Latin as calurus. Then in Early Modern times, the derivation of calurus was mistakenly attributed to another Greek word: καλαῦροψ, "shepherd's staff". This erroneous word, in its turn, was transliterated into Latin, then Arabicized with the article al-, then its spelling corrupted, to become "Alkalurops", which was thereafter applied as a star name to μ Boo.

Constellation

Light from this object takes about 113 years to reach Earth — the light you see tonight left around AD 1913 (official distance ÷ speed of light).
At magnitude 4.3 it is bright enough for the naked eye (limit about 6) — look from somewhere dark.
Declination 37.4° — it rises above the horizon in Seoul (37.6° N), so it is visible from Korea in the right season.
