Mercury was first discovered by Semou (3000 BC), and they called it Ubud-Idim-Gude-Uda. The earliest people who recorded the observation data in detail were Babylonians, who called them gu-ad or gu-utu. The Greeks gave it two ancient names, Apollo when it appeared in the morning and Hermes when it appeared in the evening, but Greek astronomers knew that the two names had the same meaning. The Greek philosopher Heraclitus even thought that Mercury and Venus revolved around the sun, not the earth. The observation of mercury is very complicated because it is too close to the sun; The only time you can observe it on earth is at sunrise or sunset.

People have known about Venus since prehistoric times. Besides the sun and the moon, it is the brightest. Like Mercury, it is usually considered to be composed of two independent stars: the morning star is called Eosphorus and the evening star is called Hesperus. Greek astronomers know this better.

There are records of Mars in Oracle Bone Inscriptions unearthed from Yin Ruins in China. It is said that this is the first discovery of Mars. But it can't be proved who discovered it first.

Like Mercury, Venus, Mars and Jupiter, they are all bright and found in ancient countries. I don't want Uranus and Neptune to be discovered by modern telescopes, so the research is difficult and the recorded data is not completely accurate.

Jupiter was called the year-old star in ancient China, and it should have a long history. At first, no one can say for sure.

Saturn was accurately recorded. It was discovered by Cassini in 1684.

Uranus Uranus was systematically searched by William Herschel through a telescope and was discovered on 1 781March 31day. It is the first planet discovered in modern times. In fact, it has been observed many times, but it was mistaken for another star (observed by john flamsteed as early as 1690, but coded as 34 Taurus). Herschel named it "Georgium Sidus" (planet Georgia) to commemorate his benefactor, the infamous king of England: George III; Some people also call Uranus "Herschel". Because the names of other planets are taken from Greek mythology, Baud first proposed to call them "Uranus" for consistency, but it was not widely used until 1850.

Neptune was discovered by British astronomer Adams and French astronomer Le Villier in 1846.

Pluto was discovered by clyde william tombaugh in 1930. (Note: In the resolution No.5 adopted by the 26th International Astronomical Union held in Prague on August 24th, 2006, Pluto was listed as a dwarf planet, named asteroid 134340, and was eliminated from the nine planets in the solar system. So now there are only eight planets in the solar system. )

I hope my answer can help you. I hope it can be adopted. Thank you.
