Comets are small irregularly shaped objects that consist of a mixture of frozen gases and non-volatile components. They usually follow circumsolar orbits, which are significantly elongated. Many of them become visible, and they can even really be seen 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. Actually, this tail causes indescribable delight among many observers. So, now we should talk more about their education.
Begin with one more definition. Comets are cold bodies that can only be seen for 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. Moreover, there are as many as thousands and even millions. It is generally accepted that these “creations” were formed from the material from which the solar system was formed, but this is only the garbage that remained after the formation of the other planets, if you can, of course, say so. Although, of course, this is far from the only mystery of these celestial bodies. Many interesting facts about comets are known to scientists.
And the latest data says that a certain part of the comets is attracted by solar gravity from different star systems at the very early stage when our solar system was formed. And the fact that they consist of invariable and original material, turns them into an extremely interesting object for study and observation. After all, this allows us to find out what conditions were at an early stage in the formation of the solar system. Comets are the real guardians of time.
It is worth noting that comets are very small when compared with planets. Their average diameter varies from 750 m to 20 km. In recent years, astronomers have discovered comets that are much further from us and possibly have a diameter of more than 300 kilometers, however, these sizes are considered small when compared with different planets. The latter have a spherical and slightly convex shape. Externally different comets. Photos show that they have an irregular shape. According to scientific studies, 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 the comets are elongated. The point farthest from the Sun is not far from Jupiter, and the closest point is near the Earth. For example, comet Halley has a completely different location. Her aphelion is located beyond the orbit of Neptune. Some comets come from faraway places in our vast solar system, and in order to complete one revolution around the sun, they need hundreds of thousands of years.
