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 6,779 km across, Mars is 53 percent of the diameter of Earth.
Its mass is 11 percent of the mass of Earth.
It keeps an average distance of 1.52 AU from the Sun, so sunlight takes 13 minutes to reach it.
A single orbit takes 1.9 years.
An average temperature of 210 K works out at -63 degrees Celsius, colder than the 15 degrees Earth averages.
2 moons are known to orbit it.
