Composed of a nucleus coma & tail
WebJul 20, 2024 · As the comet approaches the sun closely, the coma extends backwards due to solar wind. The solar wind pushes the ionized gases of the comet away from the nucleus. This is known as tail. There are two tails - dust tail and plasma tail. Plasma tail is composed of ionized gases -heavier than the dust tail and thus lies below it. WebJul 22, 2000 · FIGURE 13. Comet Encke (left) is considered a classical ‘gassy’ comet based on visible wavelength observations showing only a gas coma and no dust tail. An ISO map (right) of P/Encke and its trail at 11.5 μm, evidencing anisotropic emission and requiring the spin axis of the nucleus to lie nearly in the orbital plane.

WebOther parts of a comet result from this sublimation, include the coma, a huge cloud of dust and gas surrounding the nucleus. While the nucleus of a comet may only be 3-30 kilometers (1-18 miles) in diameter, the coma can extend for 100,000-300,000 kilometers (62,137-186,411 miles) or more. Comets are also distinctive for their tails. WebComets are frozen leftovers from the formation of the solar system composed of dust, rock, and ices. They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet. This material forms a tail that stretches millions of miles.
