they develop tails because going near the sun the comet's dust and ice particles heat up.
a comet gets a tail as it gets closer to the sun, due to solar winds.
A comet can appear larger than the sun when it is closer to Earth and has a larger visible tail. The tail of a comet can extend for millions of miles, creating the illusion of a bigger size compared to the sun when viewed from our perspective on Earth.
Comets are the celestial bodies that appear in the sky at regular but long intervals and have a tail. This tail forms as a comet gets closer to the sun, causing ice and dust to vaporize and stream away from the comet, creating a bright extended tail.
the comet moves fastest near the sun because the gravitational movement pulls it quickly and gets rid of the rock and ice on the tail
A comet is a ball of ice and dust that orbits the sun. As it gets closer to the sun, the heat and radiation from the sun cause the surface of the comet to be blown away, creating a tail that points away from the sun.

A comet - as it gets closer to the sun.

I don't think it would stretch out. The tail is the result of the comet evaporating; the tail goes away from the Sun, as a result of the solar wind.

A comet is a ball of ice and dust that orbits the sun. As it gets closer to the sun, the heat and radiation from the sun cause the surface of the comet to be blown away, creating a tail that points away from the sun.
The tail of the comet is made up of melting ice. When the comet gets close to the sun, the melted ice becomes the gaseous tail.
The increased solar wind pushes off more and more vapor and dust from the nucleus of the comet, and the tail stretches out further into space - 200 million miles is not uncommon. But even at that, the amount of solids in a cometary tail of that length is estimated to be less than would fill a standard size suitcase. One astronomer observed that a comet's tail was "as close as you can get to absolutely nothing, and still have something".
A comet's tail is only seen when the comet is relatively close to the Sun. The heat of the Sun evaporates particles from the comet and illuminates them.Far from the Sun there is neither evaporation nor illumination.If a comet tail is not visible, then probably it doesn't have a tail. The comet has a tail when it comes near the Sun, and gets heated up. It is interesting to note that the comet's tail will always point away from the Sun (it gets blown out by the solar wind), this may be "behind" or "in front of" the direction of movement of the comet.Usually, the center of a comet is composed of ices and meteoric materials. These ices are sublimated (transformation of solid into gas) under the action of sunlight when the comet goes to the sun. The dust and ice (that is transformed into gas) are expelled from the center of the comet. Ultraviolet radiation from the sun breaks the molecules of gas and dust. These broken molecules becomes bright because of exposition to ultraviolet. That's why we can see a comet's tail.
it gets a tail
The mass of material with a long tail that travels around the sun is called a comet. Comets are composed of ice, dust, and small rocky particles. The tail of a comet is formed when it gets closer to the sun, and the heat causes the ice to vaporize and create a glowing tail. The mass of a comet can range from a few million kilograms to billions of kilograms.
