Star

Apparent magnitude: 3.13 mag
Parallax: 68.92 mas → about 47.3 light-years away
Spectral type: A7IV
Right ascension: 134.8019°

Designation: HR 3569
Bayer designation: ι UMa
HIP number: 44127
IAU name adopted: 2016-07-20
Name language: Arabic
Name origin (IAU): Applied in recent times from an abbreviation of the pre-Islamic Arabian name alqafza al-thalitha, "the Third Leap," for ι and κ UMa. This pair, with the pairs λ/μ and v/ξ UMa, composed the pre-Islamic Arabian asterism qafazat al-ziba', "the Leaps of the Gazelles," imagined as the tracks left by those animals. In some later tradition, qafazat al-ziba' and adjacent asterisms were associated in a fable, where several gazelles leaped away from the Lion into a pond, leaving their tracks behind.

Constellation

Light from this object takes about 47 years to reach Earth — the light you see tonight left around AD 1979 (official distance ÷ speed of light).
At magnitude 3.1 it is bright enough for the naked eye (limit about 6) — look from somewhere dark.
Declination 48° — it rises above the horizon in Seoul (37.6° N), so it is visible from Korea in the right season.
