1. Meteor Meteor refers to a meteoroid that runs in interstellar space. When approaching the earth, it is gradually attracted by the perturbation of the earth's gravity, thus slowly entering the atmosphere. In the process of entering the atmosphere, meteoroids burn with the atmosphere to produce light and heat. In the solar system, in addition to the sun, eight planets, satellites and comets, there are a lot of dust and particles in interstellar space, which will also move around the sun and pass through the atmosphere when approaching the earth, becoming meteors and emitting light and heat.
Second, the cause of meteor formation is the burning phenomenon caused by friction. Meteoroids in interstellar space will be influenced by the gravity of the earth when they orbit the sun and pass near the earth, thus changing their orbits. If we are lucky, it will enter the earth's atmosphere. Once it enters the earth's atmosphere, it will generate friction when burning, releasing light and heat. After burning, most of them will burn to ashes, and a small part will fall to the ground, which is what we usually call meteorites.
Third, the meteor shower meteor shower refers to the astronomical phenomenon that many meteors cross the sky together from a certain radiation point. This phenomenon is endowed with a beautiful meaning. In many places in China, meteor showers will form at special times. However, you can't see it all the time. Most of the time, the flow is very small, and a large number of meteor showers will occur only during the tense period. For example, every year from June 5438 to mid-February, there will be a Gemini meteor shower in China. When the sky is clear, the atmosphere is transparent, the sky is completely dark and there is no light pollution, in some places, we can clearly see the meteor shower and make a wish.
