A Brief Introduction to Bi Su Wu's Stars

Bi Suwu, the 13 bright star in the whole day, has an irregular change in brightness between 0.75 and 0.95, because this star has entered its old age (that is, the superstar stage), which leads to irregular changes, and its changes are extremely unstable, but the brightness of the changes is not very large. This star is an orange giant with a diameter of 53 million kilometers, which is 38 times the diameter of the sun. Because the hydrogen in it has been exhausted, Biju V has evolved from a main sequence star to a red giant, and burning helium gas continues to emit light and heat. It seems to be a member of the Biju cluster in Taurus, but in fact it is only 68 light years away from the Earth, much closer than the Bibiru cluster. According to the observation of Hubble Space Telescope, this star has at least five planets, while this star is very big but has only five planets, even less than the solar system. The explanation given by scientists is that if this star is the main sequence star, it will be twice as big as the sun, and it will have at least 10 planets. But now that we have entered the superstar stage, it is likely that there will be a large number of alien planets on these planets, which leads to this. This star may end its life in 5 million to 10 million years.
