Question:
What is the temperature of a comet?

Dear Britney,
Good question. Comets share the temperature of their surroundings, so generally
a comet is as cold as the space around it. When a comet is far from the Sun its
temperature is close to absolute zero. When it nears the Sun, its ices begin to
sublimate (turn into ionized gas) as the temperature warms up a bit.
Hope this helps!

Here is a lovely picture of the temperature profile of a particular comet.
The article says the temperature of the comet varies from 260 +/-6 degrees
Kelvin to 329 +/- 8 degrees Kelvin.

tells us 260 degrees Kelvin = 8 degrees Fahrenheit; and
329 degrees Kelvin = 132 degrees Fahrenehit.
I used Google Search "Comet Temperature" and came up with several
interesting and revealing web pages.
