How does a comets appearance change as it approaches the sun?
As a comet approaches the sun, it typically develops a bright coma (cloud of gas and dust) and a tail that points away from the sun due to solar radiation. The heat from the sun causes the ice in the comet to vaporize and release dust particles, creating these features.
How does a coment change as it approaches sun?
As a comet approaches the Sun, the increasing heat causes the ice within it to vaporize, creating a glowing coma—a cloud of gas and dust—around the nucleus. This process is often accompanied by the formation of a tail that points away from the Sun due to solar wind and radiation pressure. The tail can become quite long and visible, reflecting sunlight, and may change in size and shape as the comet gets closer to the Sun. Overall, the comet becomes more active and luminous as it nears the Sun.
Correct term for the halo of light around a comet?
This is the coma, the portion of the comet that sublimates from the surface as it approaches the sun.
Is the tail of a comet created by heated of the sun?
Yes, the tail of a comet is created by the heat of the Sun. As a comet approaches the Sun, its temperature rises, causing its ices to vaporize and release gas and dust. This process creates two tails: a gas tail that points directly away from the Sun and a dust tail that follows the comet's trajectory. The interaction between solar radiation and the comet's material results in this spectacular display.
What is the correct term for the halo of light around a comet?
The halo of light around a comet is called the coma. It is made up of gas and dust that are released from the comet as it approaches the sun and is illuminated by sunlight, creating a glowing cloud around the comet.
What is produced by a comet as it approaches the sun?
A heating rock.
How does a comets appearance change as it approaches the sun?

What body forms a tail as it approaches the sun?
Comets are celestial objects that have tails and move around the sun. When a comet is moving toward the sun, its tail points toward the sun.
How does a coment change as it approaches sun?
As a comet approaches the Sun, the increasing heat causes the ice within it to vaporize, creating a glowing coma—a cloud of gas and dust—around the nucleus. This process is often accompanied by the formation of a tail that points away from the Sun due to solar wind and radiation pressure. The tail can become quite long and visible, reflecting sunlight, and may change in size and shape as the comet gets closer to the Sun. Overall, the comet becomes more active and luminous as it nears the Sun.
What blows the tails of the comet out?
Solar wind - i.e., particles coming from the Sun.
How does a comet's appearance change as it approaches the sun.why do these changes occurs?
Far out in space, the comets tail is short. As it approaches the Sun, the heat melts away some of the ice covering the surface. As it evaporates into space, a tail is formed behind the comet. Always, the tail is facing away from the sun. This is why, when we see comets, their tails are almost as long as they get.
What object produces a shimmering tail that last a few days when it approaches the sun?
A comet produces a shimmering tail that lasts a few days when it approaches the sun. This tail forms as sunlight vaporizes the comet's icy nucleus, releasing dust and gas that reflect sunlight to create a glowing effect.
Are comets related to nuclear energy?
Not directly, but as a comet approaches the sun, which is one big fusion reactor, the heat will cause the surface of the comet to vaporize, forming the comet's tail.
Why does the length of the comet tail increase as it approaches the Sun?
The length of the comet tail increases as it approaches the Sun because the heat causes volatile materials within the comet, like ice, to sublimate (turn directly from solid to gas). This process releases gas and dust particles, creating a long tail that points away from the Sun due to solar radiation and solar wind.
What does the head of a comet do?
It doesn't 'do' anything. It contains the vast majority of the mass making up the comet. Gas and dust will 'boil' off when it approaches the sun giving the comet its distinct tail
What are particles around the comet?
Particles around a comet usually include dust and gas that are released as the comet approaches the sun. These particles form a glowing cloud called a coma which envelops the nucleus of the comet. As the comet gets closer to the sun, the solar wind pushes on the particles in the coma, creating the tail that points away from the sun.
What ice of the comet turns into gas?
All ices on comets sublime to gas as it approaches toe sun.
