Yes. Halley's Comet is a comet that orbits our sun, and the definition of "Part of the solar system" is 'Any object that orbits our sun.'
Comet
Any comet visible from earth is in orbit around the sun. If the orbit is closed (elliptical), the comet will return after some period of time. If the orbit is open (parabolic or hyperbolic), the comet will escape the solar system and never return to the neighborhood.
It's in a gravitational orbit with the sun. Just like every other planet, moon, comet, asteroid, and meteoroid in the solar system.
When it is from very far away, nothing. But when a comet approaches the inner Solar System,solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. That is what we call the 'tail' of a comet.
A comet is in a solar system. A solar system is in a galaxy, so technically a comet is also in a galaxy.
