Earth
12,740 km - Mean diameter; approximate.
Earth is the rocky planet on which we live and the third planet from the Sun.
Mean-radius spherical model for Earth; actual shape is not perfectly spherical.

Sun
1,391,000 km - Diameter; approximate.
The Sun is the star at the centre of the Solar System. Its light and heat power most life and weather on Earth.
Our star, modelled with the IAU nominal solar radius. “Surface” means the visible photosphere. The core is much hotter; this is not a solid surface.
