What is the third planet from the Sun? What is the name of her companion?

The third planet from the Sun is our planet, that is, the Earth. Many people think that our planet is a ball, but in reality it is not. It has the shape of an oblate ball, or, to be more precise, a geoid. More than seventy percent of the surface of our planet is water. The satellite of the Earth is the Moon. Interesting fact: more than four hundred trees that grow on our planet from the moon. That is, the seeds of these trees visited this celestial body (they were taken on board by the crew of one of the spaceships).
