In everyday life
- Light from this object takes about 29 years to reach Earth — the light you see tonight left around AD 1997 (official distance ÷ speed of light).
- Its radius is about 14 times Earth's (NASA Exoplanet Archive).
- One orbit takes about 1,925.3 Earth days (about 5.3 years) — that is this planet's year.
