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 else can I help you with?
How does the altitude of the noontime sun change as winter approaches?
It will be lower in the sky. As the midpoint of winter passes, the noontime sun will be higher each day until midsummer.
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.
What happens to the orbital speed of an object as it approaches the sun?
As an object approaches the sun, its orbital speed increases due to the stronger gravitational pull from the sun. This increase in speed allows the object to maintain its orbit despite the stronger gravitational force it experiences closer to the sun.
Does the earth move closer to the sun every year?
Yes and no. The Earth does get closer to the Sun every year as it approaches perihelion, 147,098,290 km, around January 4th, but then it recedes as it approaches aphelion, 152,098,232 km, around July 4th.

A coment's tail aways points?
Away from the Sun
What affects does your sun have on coment's?
the comet gets repelled.
A scientist is measuring the velocity of a coment as it travels around the Sun when information does she need to determine the velocity of the coment?
She needs to know the distance traveled round the sun and the time taken.
How does the altitude of the noontime sun change as winter approaches?
It will be lower in the sky. As the midpoint of winter passes, the noontime sun will be higher each day until midsummer.
In what direction do coment tails point?
Away from the sun. The radiation blows the 'boil off', as comets are made of dirty snowballs.

What is produced by a comet as it approaches the sun?
A heating rock.

Does the sun go north or south in April?
In April, the sun appears to move northward in the sky in the Northern Hemisphere as it approaches the summer solstice. In the Southern Hemisphere, the sun moves southward as it approaches the winter solstice.

The wave would slow down as it approaches the shore.
