Comets and asteroids are two distinct types of celestial objects. Comets are icy objects that originate from the outer reaches of the solar system, while asteroids are rocky objects that are mostly found in the asteroid belt between Mars and Jupiter. Comets are known for their long, distinctive tails, which are formed as the comet's ice vaporizes when it approaches the Sun. Asteroids, on the other hand, do not have tails.

It is possible for an object to exhibit characteristics of both comets and asteroids. These objects are known as "main belt comets" or "asteroid-like comets. They are objects that spend most of their time in the asteroid belt but display comet-like activity, such as the emission of gas and dust, when they approach the Sun.

C/2013 A1 (Siding Spring) is an example of a main belt comet. It was observed in 2013 and displayed a bright coma (the glowing envelope around the nucleus) and a short tail. Despite its cometary activity, C/2013 A1 (Siding Spring) orbits in the asteroid belt, and it is believed to be a dormant comet that was reactivated by a close encounter with Jupiter.

So, while it's not common for a comet to feel like an asteroid, it is possible for certain objects to exhibit characteristics of both types of celestial bodies.
