In everyday life
- Light from this object takes about 34 years to reach Earth — the light you see tonight left around AD 1992 (official distance ÷ speed of light).
- Its radius is about 11 times Earth's (NASA Exoplanet Archive).
- One orbit takes about 600.1 Earth days (about 1.6 years) — that is this planet's year.
