What planet always has only daytime?

The universe is full of amazing planetary systems, and such a planet in Centauri is the magical "immortal star".

The name of this planet is HD 13 1399Ab. This is a planet with only day and no night forever. HD 13 1399Ab exists in a Trinary star system Centauri, which has three suns, unlike the planets in the solar system, which have only one sun. Scientists named the three suns of Alpha Centauri A, B and C respectively, in which the two suns A and B are relatively close apart, while C is far away from A and B. Observations show that the motion laws of these three suns are basically untraceable, and humans cannot accurately find the optimal solution between them.

Due to the complexity and constant change of the star's gravity system, the orbit of this planet is often unstable, which also makes this planet in a "three-day volley" for half a year, and basically in the daytime at other times. At ordinary times, the three suns HD 13 1399Ab are on duty in turn, and no matter how they turn, they are all within the irradiation range of the stars. In addition, according to astronomers' calculations, a year on this planet is equivalent to 1 100 years on earth.

HD 13 1399Ab Trinary star system has attracted numerous astronomers to observe it. With the deepening of observation, people have made many novel discoveries. Observations show that a planet similar in size to the Earth may be hidden in the galaxy where HD 13 1399Ab is located, and it is inferred that there is likely to be life on it. However, some people think that this earth-like planet is probably just a shadow. It seems that in order to truly reveal the secret of Trinary star system, human beings still need to make continuous efforts.
