Abstract

The time it takes for the Earth to travel around the sun, or its “orbital period”, is 365 days. The period of one rotation around its own axis is 23.93 hours, its largest distance from the sun 152 × 10⁶ km and the smallest distance from the sun 147 × 10⁶ km. Its diameter is 12,742 km, its mass 5.97 × 10²⁴ kg
and its density 5.5 × 10³ kg / m³.
The time of the orbital movement of the moon, or the time of its orbital period, is around 27.32 days. The radius of its orbit is 384 × 10³ km, its diameter 3476 km, its mass 7.34 × 10²² kg, with a density of 3.3 × 10³ kg / m³. The most interesting thing about the Earth is that it has been identified as the only place for intelligent life in the universe. Even without such a strange feature, the Earth still could have been magic (magic for those who might ask questions about it), but let's mention more facts about it.
