Detailed explanation-1: -COMETS vaporize when their orbits take them close to the Sun. Comets do not melt in the strict sense of becoming liquid. However, since they are composed partly of ice and other volatile compounds, they vaporize (turn directly to gas) when warmed in the vacuum of space by passing near the sun.
Detailed explanation-2: -A meteor is what happens when a meteoroid – a small piece of an asteroid or comet – burns up upon entering Earth’s atmosphere, creating a streak of light in the sky.
Detailed explanation-3: -A comet’s icy core, or nucleus, sublimates from solid to gas under the sun’s hot rays, creating a “coma” of vapor around and behind it. Eventually, after enough trips around our star, a comet will either totally disintegrate or turn into an iceless, rocky husk of its former self.
