- the Latin term occurs first in Flamsteed (1729) but is based on the Arabic idea to enumerate the stars in the cluster; in Arabic it was Awwal ad-Dabarān, The First of Dabarān (the group from which the star name "Aldebaran" derives).

In everyday life
- Light from this object takes about 162 years to reach Earth — the light you see tonight left around AD 1864 (official distance ÷ speed of light).
- At magnitude 3.7 it is bright enough for the naked eye (limit about 6) — look from somewhere dark.
- Declination 15.6° — it rises above the horizon in Seoul (37.6° N), so it is visible from Korea in the right season.
