What orbit does the comet orbit? It is a foggy weather with low quality.

Comet is a kind of celestial body with very small mass, which orbits the earth in a flat orbit.

Comet is a celestial body orbiting the sun when it enters the solar system, and its brightness and shape will change with the distance from the sun. The comet material evaporates, forming a hazy coma and a tail made of thin material flowing around the ice core. Due to the pressure of the solar wind, the tail always points away from the sun.

The orbit of a comet is very different from that of a planet. It is an extremely flat ellipse, and some even have parabolic or hyperbolic orbits. Comets with elliptical orbits can return to the sun regularly, and such comets are called periodic comets. A comet with a parabolic or hyperbolic orbit can only approach the sun once in its life, and once it leaves, it will never come back. They are called aperiodic comets. These comets may not be members of the solar system, but passers-by from outside the solar system, inadvertently broke into the solar system, and then returned to the depths of the vast universe without hesitation. Periodic comets can be divided into short-period comets (period of revolution around the sun is less than 200 years) and long-period comets (period of revolution around the sun is more than 200 years).

Why do people in China demote comets as "broomsticks"?

Because the comet, a very small celestial body, orbits the sun in a flat orbit. Its shape changes with the distance from the sun. When it is far away from the sun, it appears as a hazy point, and when it is close to the sun, its volume increases sharply. The radiation pressure of the solar wind and the sun pushes back the gas and dust in the comet, forming a long tail. Therefore, it is also called "broom star".
