Our planet is the fifth largest in the Solar System and the third largest from the Sun.
Tidal bulges in Earth’s oceans, caused by the gravitational effect of the Moon, gradually transfer momentum from the Earth’s rotation to the lunar orbit .
As a result, the rotation slows down by about 0.0018 seconds every century . In other words, each day is a little longer than the previous one, which translates into affirming that the longest day on our planet is always the current one.
The name of our planet comes from the Latin "terra", related to the verb "torror" (to dry), but it is also a Roman deity equivalent to Gea, the Greek goddess of femininity and fertility. The rest of the planets in the solar system are named after Greek or Roman gods. Not surprisingly, our planet is the largest rocky planet, and also the inner planet with the most geological activity , with 1500 potentially active volcanoes.
However, it is not exactly a "dry" planet: it is estimated that on the planet and in its interior, as well as in the atmosphere that surrounds it, there are about 1,361,620,510 km3 of liquid water. 92.2% of this volume corresponds to the salty water of the oceans . Earth is also the densest planet (more than five times the density of water).
