when a comet gets close to the sun the frozen liquid in the Nucleus starts to vaporize and turn into gas and the rock particles are released and turn to dust so somtimes you can see 2 tails one that's blue which is the gases and one that's yellow-white which is the dust.
[hope this information helps out]
by the way im only 12 and i knew this stuff off by heart

∙ 14y agoAs 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.

When a comet passes through the sun what happens to the ice?
Based on the fact that ice melts when heated, the comet's ice will melt when it even nears the sun.
What cause the tail of a comet to form?
When a comet nears the sun, and begins to out-gas, solar wind pushes the particles away. as the comet nears the sun, more & more particles are emitted, and the tail grows.
What is a famous comet and how often does it appear in the sun?
The most famous regularly returning comet is named Halley's comet. It nears the Sun every 74 years. Last seen in 1986.
How does the sun create a tail on a comet?
The sun creates a tail on a comet because of solar radiation and solar wind on the nucleus of the comet. A comet is an icy body that is seen when it passes close to the sun.
What happens when comets are far from the sun?
As the comet moves farther away from the sun, the tail begins to diminish, as the heat and solar wind pressure on the cometary nucleus decreases. Far away from the sun, near the most distant point in it's orbit, the ices in the nucleus are frozen, and the comet is quiet.

What does ice an dust do as a comet nears sun?
It will start to sublimate, as the material gets heated.
Where do the 3 main parts of a comet go?
The three main parts of a comet are the Nucleus, the Coma, and the Tail. The nucleus is the comet itself. In deep space, the comet is frozen solid and almost invisible. As the comet approaches the sun, the Sun's light heats the nucleus of the comet and causes frozen gasses to melt or sublimate, forming a sort of atmosphere around the comet. This is the "Coma" of the comet. The sunlight causes the gasses around the comet to glow. But the gravity of the comet's nucleus isn't strong enough to hold on to an atmosphere, and the Sun's rays push the glowing gasses away from the nucleus, directly away from the Sun. This stream of glowing gas is the "tail" of the comet. It's important to note that the tail of a comet doesn't drag behind the nucleus; the "tail" goes straight from the nucleus away from the Sun, so the "tail" sometimes extends AHEAD of the comet. Because the material of the comet nucleus gets melted and loses mass every pass by the Sun, comets have a limited lifespan. At some point, each comet will break apart into pieces and disappear, leaving only a meteor shower in its wake.
How does the sun create a tail on a comet?
The sun creates a tail on a comet because of solar radiation and solar wind on the nucleus of the comet. A comet is an icy body that is seen when it passes close to the sun.
Why does the coma of a comet grow as it nears the sun?
The tail of a comet, also known as its coma, grows as the comet gets close to the sun because of increases in temperature and force exerted by the solar wind. Since a comet's coma is usually composed of dust and vapor, the solar wind causes it to stream out away from the sun.
How a comet changes when it comes close to the Sun.?
As a comet nears the sun, a tail forms from the solar wind blowing off dust particles from the comet. The tail lengthens as the solar wind intensifies and the comet approaches closer and closer. In some cases, comets have been known to collide with the sun, fragment, or completely burn away due to the sun.
What happens when comets are far from the sun?
As the comet moves farther away from the sun, the tail begins to diminish, as the heat and solar wind pressure on the cometary nucleus decreases. Far away from the sun, near the most distant point in it's orbit, the ices in the nucleus are frozen, and the comet is quiet.
What is the correct term for the halo light around a comet?
The Coma is the nebulous envelope around the nucleus of a comet. It is formed when the comet passes close to the Sun.
Which part of the comet exists both when the comet is close to the sun and when the comet is far away from the sun?
Near the sun: A cometary nucleus has a "corona" (a vapor outgassing of it's nucleus, up to a million times wider than the comet itself - this is what we see as the "head" of the comet), and one or several "tails". The "tail" we usually see is the vapor trail, but sometimes a secondary gas trail is also visible. Far from the sun, it is just the nucleus. Typically 3 to 10 kilometers wide, oddly shaped, like a potato or a peanut and, somewhat surprisingly , very dark in color, like soot.
How was Halley's comet created?
It was created like any other comet: Ice chunks fuse together to the nucleus of the comet and it obtains an orbit around the sun.
