The temperature on a comet will vary by its position in its orbit. Comets have been compared to "dirty snowballs" of frozen methane, nitrogen, ammonia and carbon dioxide, with some dust and rocks mixed in.
Far from the sun, which is where comets spend most of their time, the temperature will approach the 4 degree Kelvin (minus 269 degrees Celsius) "temperature" of deep space.
As the comet falls in toward the Sun, the Sun's radiation heats the comet unevenly, causing "outgassing" as the frozen gasses of the comet are sublimated to form the tail of the comet.

Are asteroids cooler than comets?
In terms of "cool" (as in "awesome"), this question is entirely opinion. I think most people would consider comets more awesome than asteroids because comets are sometimes visible from earth. In terms of temperature, comets are made mostly of rock and ice. However, when their orbits are close to the sun, they can heat up and burn off some of the ice, forming the comet's tail. This means that a comet's temperature can vary depending on where it is in its orbit. On the other hand, asteroids in the asteroid belt have fairly regular orbits, which means that their temperature is fairly constant: cold.
