1, mercury
Mercury (English: Mercury, Latin: Mercury) is the innermost and smallest of the eight planets in the solar system and the closest planet to the sun.
China, known as Chen Xing, has the largest orbital eccentricity among the eight planets. It orbits the sun once every 87.968 Earth Days and rotates once every 2.0 1 for 3 times.
Mercury is a planet similar to the earth. Because it is close to the sun, it will only appear as a morning star in the morning or as a dim star at dusk. Mercury is usually invisible in the sun unless there is a solar eclipse.
2. Venus
Venus, one of the eight planets in the solar system, is the second planet in the distance sequence from the sun, with a distance of 0.725 astronomical unit. It is the closest planet to the earth (Mars is sometimes closer).
The ancient Romans called it Venus, China called it Chang Geng, Qi Ming, Taibai or Taibai Venus, and Aphrodite in ancient Greek mythology. Period of revolution is 224.7438+0 Earth Day.
The brightness in the night sky is second only to the moon, and Venus will reach its maximum brightness before sunrise or after sunset. It appears in the eastern sky in the morning and is called "Qi Ming". Dusk is in the west of the sky, which is called Chang Geng.
3. Earth
The earth is one of the eight planets in the solar system, also called Gaia. It ranks third in the order from near to far from the sun, and it is also the earth-like planet with the largest diameter, mass and density in the solar system, with a distance of1.500 million kilometers from the sun.
The earth rotates from west to east and revolves around the sun at the same time. At present, there is a natural satellite-the moon, which forms a celestial system-the earth-moon system. It originated from the primitive solar nebula 4.6 billion years ago.
4. Mars
Mars is one of the eight planets in the solar system and the fourth planet in the solar system from the inside out. It is a terrestrial planet, with a diameter of about 53% of the Earth's and a mass of 1 1% of the Earth's. Due to the axial tilt, the rotation period is similar to that of the earth, and one circle is about twice that of the earth.
The orange appearance is the surface hematite (iron oxide). In China's ancient books, Mars was called "the twinkling star", while in ancient western countries (ancient Rome) it was called "the star in the myth of Mars".
5. Jupiter
Jupiter, also known as Jupiter and Jupiter, is the largest planet with the fastest rotation among the eight planets in the solar system and the fifth planet from the inside out. Its mass is one thousandth of the mass of the sun (to be precise, it is between a quarter of 1024 and a fifth of 1025), which is 2.5 times the mass of the other seven planets in the solar system.
Because Jupiter, Saturn, Uranus and Neptune are all gaseous planets, they are also collectively called woody planets (Jupiter and Saturn are collectively called gaseous giants).
6.saturn
Saturn (English Saturn, Latin Saturn) is one of the eight planets in the solar system, with the sixth distance (from near to far) from the sun. The mass and diameter are second only to Jupiter, and they belong to the gas giant planet with Jupiter. In ancient Europe (ancient Greece), Saturn was called Cronian, and in ancient China, it was also called revitalization or filling star.
7. Uranus
Uranus, one of the eight planets in the solar system, is the seventh planet in the solar system from the inside out (18.37~20.08 astronomical units). 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.
Herschel named it "Georgium Sidus" (the planet of Georgia) in memory of his benefactor.
8. Neptune
Neptune, also known as the planet under the pen, is a distant planet among the eight planets. According to the distance between the planet and the sun, Neptune is the eighth planet, the fourth largest planet in diameter and the third largest planet in mass.
Its brightness is only 7.85, which can only be seen by astronomical telescopes. Because of its light blue light, westerners call it Neptune, the sea god in Roman mythology. Translated into Neptune in Chinese.
9. Pluto
Pluto (asteroid number: 134340 Pluto; ; Astronomical code:? , Unicode code: U+2647), another name, Yan Wangxing, ghost star, is a dwarf planet in the Kuiper Belt. Pluto was the first kuiper belt object to be discovered. Pluto is the largest and second largest dwarf planet in the solar system.
