This star is a star in the solar system. Why is it flashing?

Because the flow of the atmosphere is different from the density in different places and the direction of light propagation is different, the stars will twinkle. For example, the weather is very hot in summer, and sometimes the ground seems to fluctuate, and the principle is the same. When astronauts are in the universe, the stars they see are stationary because they are disturbed by the atmosphere. What is a star? Stars are luminous spherical plasmas gathered together by gravity. Our common sun is the nearest star. Some stars are very close in the sky, forming twelve constellations and some star groups we hear in our life, such as Sirius, Altair and Vega. They also have the same principle as the sun, and they all emit light by themselves. Planets themselves can't shine. They keep going around the stars, and they rotate in the same direction as the stars. Planets also need certain requirements. Their mass must reach a certain size, close to a sphere, and cannot react on its own like a star. There are countless types of celestial bodies in the universe. From the point of view of the earth where we live, there are many other large and larger stars between us and the observed stars. And some of them may have visual overlap. One of the most obvious examples of this phenomenon is our earth, moon and sun. Sometimes, due to the exact change of position, there will be some situations such as total lunar eclipse, total solar eclipse and half lunar eclipse, but these situations are also relatively rare because the probability of coincidence is relatively small. Some stars that don't twinkle are actually mostly stars close to the earth. They look about the size of a dinner plate, not just a point. So the light emitted by the planet does not have to be refracted so much to reach the earth, and it will not be swallowed up, so the light reaching the earth is stronger.
