Except when comets are far away from the sun, their long, bright and sparse tails give people the impression that comets are close to the earth, even within our atmosphere.In 1577, Tycho pointed out that comets did not show different directions when viewed from different places on the earth, so he correctly concluded that they must be far away.Whenever comets approach the sun, their brightness increases rapidly. Observation of comets far away from the sun shows that they move along a highly elongated ellipse, and the sun is at a focus of the ellipse, consistent with Kepler's first law.Most of the time comets travel far away from the sun, where they are invisible. They can only be seen when they are close to the sun. About 40 comets have a very short revolution period (less than 100 years), so they appear one after another as the same celestial body.

In 1066 AD, the eve of the Norman invasion of England coincided with the return of Halley's Comet.At that time, people looked at this strange celestial body with a long tail in the night sky with complex feelings, thinking it was a war warning and prediction given by God.Later, the Normans conquered England. The wife of Norman commander embroidered the scene of Halley's Comet's return on a tapestry to commemorate it.Chinese people refer to comets as "broomsticks" and "disaster stars".There are many things in Chinese and foreign history that link the appearance of comets with human wars, famines, floods, plagues and other disasters.
A typical comet consists of a nucleus, a coma and a tail.The nucleus of a comet is composed of relatively dense solid particles, and the cloud like brightness around it is the comet.The nucleus and hair of the comet are called the head of the comet, and the long tail behind it is called the tail of the comet.This broom shaped tail is not born, but is formed by the pressure of sunlight when approaching the sun, so it often extends away from the sun.The size of the comet, any planet in the solar system, can not be compared with the big comet. The famous Halley's comet has a diameter of 570000 kilometers.The largest comet on record has a diameter of 1.85 million kilometers. As for its length, the largest comet is hundreds of millions of kilometers from head to tail.Of course, there are many comets in space, but most of them are small comets.

When introducing the modern solar system theory of western science in the book A Brief Introduction to Astronomy, the book wrote: "The science of astronomy has a long history, but the ancients all called the sky round and the place round." This "ancients" should include the Chinese, and "the sky round and the place" is obviously the traditional concept of China.When introducing comets, the book wrote that comets are strange stars, with a head and a tail. They are popularly called "broom stars" because of their shape. At the same time, words similar to "broom stars" include "broom men", "broom eyebrows", "broom heads", etc.

European Space AgencyThe successful launch of the Rosetta comet detector has attracted widespread attention.Comet is also called "broom star". Where is the "charm" that attracts people?What kind of comet does Rosetta want to observe?The comet to be detected by Rosetta is named Chuliumov Glasimenko, after the two former Soviet astronomers who discovered it in 1969.It is a comet orbiting the sun. The diameter of the comet nucleus is about 3 to 5 kilometers. It takes about 6 years and 6 months to fly around the sun.
It is estimated that after the comet reaches the nearest point about 500 million kilometers away from the sun, its frozen surface begins to evaporate, and the gas and dust diffused will form a long tail, which can extend tens of thousands of kilometers. When the comet is illuminated by the sun, the "broom" visible to the naked eye on the earth will appear.
Astronomers believe that comets are made up of materials in the early days of the solar system. Because of its extremely low temperature and in the extremely cold space of the universe, comets have almost always maintained their initial state of formation since the birth of the solar system 4.6 billion years ago. The study of comets will help mankind to uncover the mystery of the formation of the solar system.Some comets may have foreign organic components, and millions of organic molecules together form polymers, which may form proteins necessary for lifeDeoxyribonucleic acidAnd RNA molecules.Therefore, as experts from the European Space Agency said, detecting comets can help to explain the origin of life on Earth.
In addition,Comet strikes the earthIt will cause disasters, and the water on the earth may also come from comets.Therefore, the study of comets will also help reveal these mysteries that have puzzled mankind for a long time.By detecting the nature and composition of comets, we can also understand the physical properties and chemical composition of the sun.
