Planets are massive enough to pull themselves round and to have cleared their orbit of other debris — the second part is the line the solar system's dwarf planets fall short of.
At 12,742 km across, Earth is close to the diameter of Earth.
Its mass is close to the mass of Earth.
It keeps an average distance of 1 AU from the Sun, so sunlight takes 8 minutes to reach it.
A single orbit takes 1.0 years.
An average temperature of 288 K works out at 15 degrees Celsius, colder than the 15 degrees Earth averages.
One moon is known to orbit it.
