An Asteroid or Minor planet refers to a celestial body in the solar system that is similar to a planet orbiting the sun, but is much smaller in size and mass than a planet. Most asteroids are concentrated in the asteroid belt between the orbits of Mars and Jupiter. Asteroids are generally considered to have evolved from asteroid planetesimals during the formation of the solar system.
It is the largest number of celestial bodies found in the solar system. According to the data of the Asteroid Center on June 65438+February 3, 2020, there are 1026572 asteroids in the solar system, including exoneptune objects, about 57% of which have been officially numbered, but this is probably still only a small part of all asteroids.
Influenced by the progress of observation technology and the increasing number of observation tasks since 2000, the number of asteroids discovered is increasing every day, and now thousands of new asteroids can be discovered every month. After 1890, photography was introduced into astronomy, which greatly promoted the development of astronomy.
Before discovering an asteroid, astronomers must record the position of each suspicious star for a long time and compare their changes with those of the surrounding stars. But on the photographic negative, asteroids moving relative to the stars can be easily determined by pulling a line on the negative.
And with the enhancement of the sensitivity of the negative film, it will soon be more sensitive than the human eye, and even darker asteroids can be found. The introduction of photography technology has greatly increased the number of asteroids discovered. More accurate data can be obtained through radar observation. Astronomers use radio telescopes as high-power generators to emit strong radio waves to asteroids.
