- From the Arabic word tihyat, said to be the singular form of al-tahayi, an pre-Islamic Arabian name of unknown meaning and disputed identification. In some sources, the plural al-tahayi is assigned to η, μ, and v Gem. As originally applied in recent times, η was "Tejat Prior," and μ was Tejat Posterior."

In everyday life
- Light from this object takes about 232 years to reach Earth — the light you see tonight left around AD 1794 (official distance ÷ speed of light).
- At magnitude 2.9 it is bright enough for the naked eye (limit about 6) — look from somewhere dark.
- Declination 22.5° — it rises above the horizon in Seoul (37.6° N), so it is visible from Korea in the right season.
