How does a comet get its energy?
Since comet tails are shaped by sunlight and the solar wind, they always point away from the sun. We can see a number of comets with the naked eye when they pass close to the sun because their comas and tails reflect sunlight or even glow because of energy they absorb from the sun.

What happens to a comet as the sun begins to heat it?
As a comet approaches our Sun, it begins to heat up and the ice begins to sublimate — to change from a solid to a gas with no liquid stage. Some of the dust is left behind as the ice sublimates. It forms a dark, protective crust on the surface of the nucleus and slows the melting.
What happens to a comet as it gets closer to the Sun?
As the comet gets closer to the Sun, some of the ice starts to melt and boil off, along with particles of dust. These particles and gases make a cloud around the nucleus, called a coma. The coma is lit by the Sun. The sunlight also pushes this material into the beautiful brightly lit tail of the comet.
How are comets formed in the Solar System?
Analysis of the Stardust samples suggests that comets may be more complex than originally thought. Minerals formed near the Sun or other stars were found in the samples, suggesting that materials from the inner regions of the solar system traveled to the outer regions where comets formed.
How big is the nucleus of a comet?
It takes comet Swift-Tuttle 133 years to orbit the sun once. It takes comet Swift-Tuttle 133 years to orbit the sun once. Resembling a chicken leg, the nucleus of comet 19P/Borrelly is small and measures approximately 2.98 miles (4.8 kilometers) in diameter.
What did people think Comets were in the past?
In the distant past, people were both awed and alarmed by comets, perceiving them as long-haired stars that appeared in the sky unannounced and unpredictably.
