Question

Чем отличаются движение комет от движения планет?

Answer 1

Планеты обращаются вокруг Солнца в одном направлении по почти круговым орбитам, лежащим примерно в одной плоскости (эклиптики), а кометы движутся как в прямом, так и обратном направлениях по сильно вытянутым орбитам, наклоненным под различными углами к эклиптике

Answer 2

Difference between the Movement of Comets and Planets

The movement of comets and planets differs in several ways. Here are the key differences:

1. Orbits: Comets and planets have different types of orbits. Planets generally have nearly circular orbits around the Sun, while comets have more elongated and elliptical orbits that can take them much farther from the Sun.

2. Composition: Comets and planets are composed of different materials. Planets are primarily made up of rock and metal, while comets are composed of a mixture of ice, dust, and rocky material. When a comet gets closer to the Sun, the heat causes the ice to vaporize, creating a glowing coma and a tail that can be seen from Earth.

3. Size: Planets are generally much larger than comets. Planets like Earth, Mars, and Jupiter have a significant mass and size, while comets are relatively small in comparison. Comets typically range in size from a few kilometers to tens of kilometers in diameter.

4. Frequency: Comets are less common than planets in our solar system. While there are eight planets in our solar system, there are only a few thousand known comets. Comets are often referred to as "dirty snowballs" or "icy dirtballs" because of their composition and appearance.

5. Visibility: Comets are often visible from Earth when they come close to the Sun. As the ice in a comet vaporizes, it creates a glowing coma and a tail that can be seen from Earth. Planets, on the other hand, are visible throughout the year and can be observed in the night sky without the need for a telescope.

In summary, the movement of comets and planets differs in terms of their orbits, composition, size, frequency, and visibility. Comets have elongated orbits, are composed of ice and dust, are relatively small, less common, and become visible when they come close to the Sun. Planets have nearly circular orbits, are composed of rock and metal, are larger in size, more common, and visible throughout the year.
