How many planets are there on the earth?

In the past, there were nine planets in the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. Later, with the in-depth study, it was found that Pluto was incompatible with the other eight planets, and its volume and trajectory were very different. So Pluto was excluded from the list of nine planets, leaving only eight planets in the solar system.

Most of the eight planets also rotate in the same direction as the revolution. Only Venus and Uranus are two exceptions. Venus rotates in the opposite direction to the revolution direction, while Uranus rotates "lying" at an angle of 97 with the revolution orbit.

Brief introduction of the eight planets

1, Mercury: the planet closest to the sun and the smallest of the eight planets, belonging to the Earth-like planet.

2. Venus: the second closest planet to the sun, known as the "sister star" of the earth, belongs to the earth-like planet.

3. Earth: The home where we live, the Earth, is also one of the eight planets, belonging to the Earth-like planet.

4. Mars: adjacent to the earth, smaller in size and mass than the earth, it is basically a desert planet and belongs to a terrestrial planet.

5. Jupiter: the largest planet among the eight planets, and the fastest rotation among the eight planets, belonging to a giant planet.

6. Saturn: Saturn is the second largest planet among the eight planets and belongs to a giant planet.

7. Uranus: Uranus revolves around the sun almost horizontally and belongs to a distant planet.

8. Neptune: Neptune is blue, and the fourth planet among the eight planets belongs to a distant planet.
