In everyday life
- Light from this object takes about 39 years to reach Earth — the light you see tonight left around AD 1987 (official distance ÷ speed of light).
- Its radius is about 3.8 times Earth's (NASA Exoplanet Archive).
- One orbit takes about 15.5 Earth days — that is this planet's year.
