Star knowledge: The solar system is a collection of all celestial bodies with the sun as the center and constrained by the sun's gravity: 8 planets, at least 165 known satellites, 5 confirmed dwarf planets and hundreds of millions of small celestial bodies in the solar system. A cluster is a celestial system consisting of a dozen to millions of stars with the same origin and strong mechanical connection with each other.
Stars are composed of hot gases. They are spherical or quasi-spherical celestial bodies, which can emit light and heat by themselves. The greater the mass, the shorter the life of a star, and the smaller the mass, the longer the life of a star. Most stars are between 1 100 million years old.
A planet usually refers to a celestial body that surrounds a star without giving off light. Its revolution direction is often the same as the rotation direction of the surrounding stars. Generally speaking, the planet needs to have a certain mass, and the mass of the planet should be large enough to approximate a sphere, so that nuclear fusion reaction can occur like a star. Generally speaking, a planet must be more than 800 kilometers in diameter and more than 500 million tons in mass. The so-called "nine planets" in the solar system is a popular saying in history, namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. Resolution No.5 adopted by the 26th International Astronomical Union in Prague on August 24th, 2006 classified Pluto as a dwarf planet, named it asteroid 134340, and eliminated it from the nine planets in the solar system. So now there are only eight planets in the solar system.
Meteor refers to the light trail produced by meteoroids (usually including cosmic dust particles and solid blocks) running in interstellar space, which are attracted by the earth due to the perturbation of the earth's gravity, and then enter the earth's atmosphere and burn with it. Meteorites originally moved around the sun, and when passing near the earth, they changed their orbits under the action of the earth's gravity, thus entering the earth's atmosphere. There are several kinds of meteors: single meteor, fireball and meteor shower. Most visible meteoroids are similar to sand grains and weigh less than 1 g. The velocity of meteors entering the atmosphere is between 1 1km/s and 72 km/s.
