Summarize the characteristics of each of the nine planets in one sentence.

the English name Mercury comes from the Roman god mercury. The symbols are a circle above, a crossed short vertical line below and a semicircle (Unicode:? ). It's the shape of Mercury's wand. In the 5th century, Mercury was actually considered as two different planets, because it often appeared alternately on both sides of the sun. When it appears in the evening, it is called mercury; But when it appeared in the morning, it was called Apollo in memory of Apollo, the sun god. Pythagoras later pointed out that they were actually the same planet. In ancient China, mercury was called "the morning star".

The ancients in China called Venus "Taibai" or "Taibai Venus", also called "Qiming" or "Chang Gung". The ancient Greeks called Aphrodite, the goddess of love and beauty in Greek mythology. In Roman mythology, the goddess of love and beauty is Venus, so Venus is also called Venus. Venus' astronomical symbol is represented by Venus' dressing mirror. Phase change of Venus Venus, like the moon, also has periodic round and round changes (phase changes), but because Venus is too far away from the earth, it can't be seen with the naked eye. About the phase change of Venus, Galileo once used it as strong evidence to prove Copernicus' Heliocentrism.

the earth is one of the planets in the solar system, ranking third in the order from near to far from the sun. It is the largest terrestrial planet in the solar system, and it is also the only planet with life confirmed by modern science. The age of planets is estimated to be about 4.5 billion years (4.5×19). Shortly after the formation of the planet, it captured its only natural satellite-the moon. The only intelligent creature on the earth is human.

Because it looks blood red in the night sky, in the west, it is named after Mars mythology, the god of war in Roman mythology (or Ares in Greek mythology). In ancient China, it was called "flicker" because it was as bright as fire. Mars has two small natural satellites: Phobos and Deimos (the names of sons of Ares). Both satellites are small and strange in shape, and may be asteroids captured by gravity. The prefix areo- in English refers to Mars.

Jupiter is one of the nine planets in the solar system, ranking fifth in the order from near to far from the sun. It is also the largest planet in the solar system and the fastest rotating planet. China used it to record the years in ancient times, so it was called the year-old star.

In the west, it is called Jupiter, the king of gods in Roman mythology, equivalent to Zeus in Greek mythology.

Saturn is a giant gas planet and the second largest planet in the solar system after Jupiter. Saturn's English name Saturn (and Saturn's name in most other European languages) is named after the Roman god Saturnian. In ancient China, it was called zhenxing or filling stars.

Uranus, one of the nine planets in the solar system, ranks seventh outside Saturn and inside Neptune. Its color is gray blue, and it is Gas Giant gas planet. Uranus is the third largest planet in the solar system in terms of diameter; But if calculated by mass, it is lighter than Neptune and ranks fourth. Uranus was named after Uranus, the god of Greek mythology.

Neptune is the eighth of the nine planets in the solar system, and it is a giant planet. Neptune is the first planet discovered by celestial mechanics calculation. Because the orbit of Uranus is different from that calculated, in 1845, John Kev Adams and Eban Qin Weiye calculated the possible position of an unknown planet outside Uranus. On September 23, 1846, the director of the Berlin Observatory, John Gforrien Gail, really discovered a new planet: Neptune.

At present, Neptune is the second farthest planet from the sun in the solar system. Neptune's name is Neptune in Roman mythology.

Pluto is the farthest and smallest of the nine planets in the solar system, which was discovered in 193. Because it is farthest from the sun, it is also very cold, which is very similar to the place where Prouteau, the god of the underworld, lived in Roman mythology, so it is called "Pluto".
