Comets are small, irregular objects that are made up of a mixture of frozen gases and non-volatile components. They usually follow circumsolar orbits, which are considerably elongated. Many of them become visible, and it is even possible to see them through an ordinary telescope. In particular, they are clearly visible when they are close to the Sun: then they become much brighter.
Comets are celestial bodies consisting of a nucleus and a bright tail, which is an accumulation of cosmic dust and gases. In fact, this tail causes indescribable delight among many observers. So, now we should talk more about their education.
Start with one more definition. Comets are such cold bodies that can be seen for only one reason. The tail does not actually emit light, but reflects the sun. Comets are permanent celestial bodies in the solar system that are directly related to the Luminary by gravity. And there are thousands and even millions of them. It is generally accepted that these “creatures” were formed from the material from which the solar system was formed, but this is only the debris that remained after the formation of the remaining planets, if so, of course, you can say. Although it is certainly far fromthe only mystery of these celestial bodies. Many interesting facts about comets are known to scientists.
And the latest data says that some of the comets are attracted by solar gravity from different star systems at a very early stage, when our solar system was formed. And the fact that they consist of unchanged and original material makes them an extremely interesting object for study and observation. After all, this allows us to find out what conditions were at an early stage of the formation of the solar system. Comets are the true keepers of time.
I would like to note that comets are very small compared to planets. Their average diameter varies from 750 m to 20 km. In recent years, astronomers have discovered comets that are much further away from us and may have a diameter of more than 300 kilometers, but these sizes are considered small when compared with various planets. The latter have a spherical and slightly convex shape. Completely different outwardly comets. Photos show that they have an irregular shape. According to scientific research, astronomers have concluded that comets are very fragile.
Comets must, of course, obey the laws of motion, just like other objects. There are, of course, certain differences. There are many orbits around the sun. Those that belong to the planets are rounded, and the orbits of comets are elongated. The farthest point from the Sun is located near Jupiter, and the nearest one is near the Earth. For example, atHalley's comet is a completely different arrangement. Its aphelion is located beyond the orbit of Neptune. Some comets come from far away in our vast solar system and take hundreds of thousands of years to complete one revolution around the Sun.
