What planets are there in the solar system?

The solar system includes planets such as Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, as well as some satellites and small celestial bodies.

1, mercury

Mercury is the closest planet to the sun among the eight planets in the solar system. China called them stars. It orbits the sun once every 87.968 Earth Days and rotates once every 2.0 1 for 3 times.

2. Venus

Venus is the second planet out of the sun among the eight planets in the solar system, with an orbital period of 224.7 days and no natural satellites.

3. Earth

The earth is the third planet from the sun and the only celestial body known to human beings that breeds and supports life. About 29.2% of the earth's surface is land composed of continents and islands. The remaining 70.8% is covered by water, mainly oceans, bays and other saline water bodies, but also lakes, rivers and other fresh water bodies, which together form the hydrosphere.

4. Mars

Mars is the fourth planet among the eight planets in the solar system, which is about 1.6 astronomical units away from the sun, and period of revolution is about two years on Earth. The maximum brightness of Mars from the earth is -2.9 1 apparent magnitude, and the minimum brightness of Mars from the earth is 1.84 apparent magnitude.

5. Jupiter

Jupiter is the largest and fastest rotating planet among the eight planets in the solar system, and the fifth farthest planet from the sun. Its mass is one thousandth of that of the sun and 2.5 times that of the other seven planets in the solar system combined.

6.saturn

Saturn is one of the eight planets in the solar system, and its distance from the sun ranks sixth in the solar system. Saturn is a gas giant planet. In ancient China, people called Saturn Ryuboshi, and in ancient Europe, it was called Saturn.

7. Uranus

Uranus is one of the eight planets in the solar system and the seventh planet in the solar system from the inside out. Its volume ranks third in the solar system (larger than Neptune) and its mass ranks fourth (smaller than Neptune), and it rotates almost horizontally around the sun.

8. Neptune

Neptune is one of the eight planets in the solar system and the farthest planet from the sun in the known solar system. The semimajor axis of Neptune's orbit is 30. 1 astronomical unit, period of revolution's is 164.8 years, and its mass is 17. 1 earth's mass (the third place, slightly larger than its neighbor Uranus), and its radius is 3.9 times that of radius of the earth (the fourth place).
