In everyday life
- Light from this object takes about 20 years to reach Earth — the light you see tonight left around AD 2006 (official distance ÷ speed of light).
- Its radius is about 2.3 times Earth's (NASA Exoplanet Archive).
- One orbit takes about 647.6 Earth days (about 1.8 years) — that is this planet's year.
