The morning star refers to Venus.
Morning star is the ancient name for Venus, which appears in the early east and late west. Before and after daybreak, you will sometimes see a particularly bright morning star on the eastern horizon. It is not a light source, and people call it the "Morning Star." At dusk, a very bright evening star sometimes appears in the western afterglow. People call it "Chang Geng Star". These two stars are actually the same star, Venus.
In Chinese people, it is called "Taibai" or "Taibai Venus". The first morning star that comes out every night is Venus. There are many legends about it in ancient times. In Greek and Roman mythology, she is the goddess Venus. In Tolkien's mythology of Middle-earth, he is E?rendil the Great Navigator. It is the closest planet to Earth. It reaches its maximum brightness just before sunrise or after sunset, and its brightness ranks second in the night sky after the moon.
Star introduction
The rotation direction of Venus, like Uranus, is opposite to that of other planets, from east to west. Therefore, from Venus, the sun rises in the west and sets in the east. The orbit of Venus around the sun is an ellipse that is very close to a perfect circle, with a deviation of no more than 1 degree and close to coinciding with the ecliptic plane. Its revolution speed is about 35 kilometers per second, and its revolution period is about 224.70 days. However, its rotation period is 243 days, which means that Venus's rotation sidereal day is longer than a year.
However, according to Earth standards, if one day is counted from one sunrise to the next, a year on Venus is much shorter than 243 days. This is because Venus rotates in the opposite direction. On Venus, the sun rises in the west and sets in the east. The cycle of day and night from one sunrise to the next is only 116.75 days on Earth. Venus's reverse rotation may have been caused by a collision between Venus and other asteroids a long time ago.
