Webhead: nucleus and coma; nucleus: composed of (solid) ices and a lesser amount of dust; typically a few km in diameter; coma: nearly spherical cloud of mostly neutral gases sublimed from the nucleus inside of ~3 AU; tens of thousands of km diameter; tail: dust tail and ion tail; both point generally away from the Sun WebComa. As the comet approaches the sun, the ice on the surface of the nucleus transforms into a gas, forming a cloud known as the coma. Tail(s). Radiation from the sun pushes dust particles away from the coma, forming a dust tail, while charged particles from the sun convert some of the comet’s gases into ions, forming an ion 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. WebThe gas molecules flow off the nucleus surface, carrying with them silicate and organic dust that had been embedded in the ices. The outflowing mix of materials then forms the cometary coma, the comet’s atmosphere. Because cometary nuclei are small, their gravity is too weak to retain that atmosphere, and it flows freely out into space.
WebThe nucleus, or body, of a comet has been described as a dusty snowball consisting of tiny pieces of rocky material embedded in a mass of ice and frozen gases. The nuclei of most comets are believed to range from 1 - 10 kilometers (.6 - 6 miles) in diameter. The coma is a cloud of gases that surrounds the nucleus of a comet.
