Stars are comparable to many beautiful things in nature. They shine like fireflies, glitter like gemstones, they guide and illuminate people like streetlights. Each star is different, each star is unique, and each star is dazzling and attractive. Let's take stock of the stars.

The brightest planet

On earth, humans can see five planets with the naked eye, of which Venus is the brightest. Although Venus is far less bright than the sun and moon, it is 14 times brighter than the famous Sirius (the brightest star in the day except the sun), just like a dazzling diamond.

Venus is not only very bright, but also very special. It is the only large planet with reverse rotation in the solar system. Its rotates in the opposite direction to the other planets, from east to west. Therefore, on Venus, the sun rises in the West and sets in the East.

The oldest star

At 36000 light-years from the earth, there is a giant star named he0107-5240, which is about 13.2 billion years old.

The fastest star

When looking at the stars, people are used to looking for them in fixed positions. In fact, many stars are running at high speed, and some of them run far faster than we can imagine.

In 2005, astronomers in the United States discovered a star with a speed of more than 2.4 million kilometers per hour. Astronomers speculate that the star's speed is likely due to the encounter between a star and a supermassive black hole in the center of the Milky way about 80 million years ago. However, the high-speed star will eventually fly away from the Milky Way galaxy, at which point it will also be the first star to "escape".

The hottest white dwarf

The sun is the source of light and heat on the earth, and when we face the starry sky at night, we see a little glittering lights, but we don't realize that some of the stars can also emit heat.

A white dwarf named H1504 + 65 (the dense debris of a dead star) has a surface temperature of 200000 degrees Celsius, 30 times hotter that the sun.
