Final answer:
Comets and asteroids are objects found in some galaxies and can also be found outside our solar system.
Step-by-step explanation:
Comets and asteroids are objects that are found in various galaxies and also exist outside our solar system. Comets are icy bodies composed of frozen gases, dust, and rock, that orbit the Sun in elongated orbits. Asteroids, on the other hand, are rocky objects that also orbit the Sun, but in more circular or elliptical orbits. Both comets and asteroids can be found in other galaxies, as they are formed through similar processes as in our own solar system.
