Comets are celestial bodies that resemble asteroids but are primarily composed of ice, including carbon dioxide, methane, and frozen water, mixed with dust and various minerals.
Most comets have elliptical orbits.
The orbits of comets differ from other objects in the Solar System in that they do not lie close to the ecliptic plane but are randomly distributed throughout space.
Many comets originate from a region known as the Oort Cloud. Here, the temperatures are very low, causing substances such as carbon dioxide, methane, and water to freeze. As they approach the Sun, the rising temperatures cause the comet’s material to vaporize, and under the pressure of the solar wind, this creates dust tails and gas tails, giving them a brush-like appearance.
