In everyday life
- Light from this object takes about 19 years to reach Earth — the light you see tonight left around AD 2007 (official distance ÷ speed of light).
- Its radius is about 1.5 times Earth's (NASA Exoplanet Archive).
- One orbit takes about 18.6 Earth days — that is this planet's year.
