![]() Hence the correct option is Option(B) which is away from the sun.Īs this is a fact-based question so you need to know about the mechanism of formation of comet and comet’s tail otherwise you cannot get the correct answer. This implies that they always point away from the direction of the Sun and thereby guide the comet into its orbit after perihelion. (b)Centripetal forces- A force that works in a circular direction on a comet and is directed towards the sun around which the comet is passing.īy interaction with either the solar wind or sunlight photons, comet tails are formed. answer answered A comet’s tail always points. (a)Centrifugal forces- A force that emerges from the inertia of the comet, which tends to work in a circular direction on a comet and is guided away from the sun around which the comet is travelling. These dust particles combine to form ice rocks which, under the force of gravity, bind together.Ĭomet moves around the sun in an elliptical path. A comet's building block is fragments of dust covered with water ice and other molecules. They are composed of ashes, ice, carbon dioxide, nitrogen, ammonia, etc. Comet seasons vary from a couple of years to millions of years. The time it takes for a comet to complete an orbit is known as the period of a comet. They are small, frozen objects that in space emit dust or gas and orbit the Sun. This implies that they always point away from the direction of the Sun and thereby guide the comet into its orbit after perihelion. The 'Dirty Snowballs' of Space are often referred to as Comets. Sun's radiation pressure pushes this tail away from itself. Comet Hale-Bopp, also called the Great Comet of 1997. Consequently, as depicted in Figure 14.9, the tail always lies outside the comets orbit and actually leads the comet during the portion of the orbit that is. They seem to disappear as they move back to the outer solar system. Comets appear for only a short time when they are near the Sun. ![]() The coma is bright because it reflects light from the Sun ( Figure below). This vapor mixed with dust streams out of the nucleus of the comet giving the comet a tail. The streams of dust and gas thus released from a huge extremely tenous atmosphere around the comet called coma and force exerted on coma by the suns radiation. The tail always points away from the Sun. ![]() The solar radiations vaporize the volatile materials. Hint: Comets are composed of many things which can also be volatile. ![]()
