In everyday life
- Light from this object takes about 40 years to reach Earth — the light you see tonight left around AD 1986 (official distance ÷ speed of light).
- Its radius is about 14 times Earth's (NASA Exoplanet Archive).
- One orbit takes about 2,288 Earth days (about 6.3 years) — that is this planet's year.
