What happens when a comet passes by the sun?

Answer 1

This is my Guess,

As it approches the sun the comets icy surface is blasted off by the suns heat and solar wind thereby forming a tail. As the comet passes the sun the tail always points away from the sun. Solar wind always coming from the direction of the sun pushes the tail away from the sun. Once into deep space again the tail dissapears as no force is acting on the surface anymore to produce the steam and gas and also particles.

Answer 2

AU is "astronomical unit," or average distance between earth and sun. At 3 AU comets warm up enough they begin outgassing, which produces a tail. This tail is generally blown back by the solar wind, pointing away from the sun.

Answer 3

The heart of the comet will develop gas jets of steam as the core heats up. The tail of the comet will glow and trail PERPENDICULAR to the Sun regardless of the motion of the comet in relation to the Sun. The gravitational pull of the Sun will accelerate the comet.

Answer 4

A comet's tail lengthens as it approaches the sun due to greater solar winds. A comets tail always faces away from the sun.

Answer 5

As a comet approaches the Sun, it changes. Ices of water, methane, and ammonia vaporize because of the heat from the Sun, releasing dust and bits of rock.

Answer 6

As it gets close to the sun, temperature will rise, thus evaporating some amounts of water in comets. Those evaporated water will become the tail of the comet.
