In everyday life
- Light from this object takes about 37 years to reach Earth — the light you see tonight left around AD 1989 (official distance ÷ speed of light).
- Its radius is about 13 times Earth's (NASA Exoplanet Archive).
- One orbit takes about 14,892 Earth days (about 40.8 years) — that is this planet's year.
