Yes. Comets are tiny; the Milky Way is enormous.
No - The volume of the Milky Way galaxy is larger than the volume of its host black hole. The accumulated mass of the Milky Way galaxy is greater than the mass of its host black hole. The density of the Milky Way galaxy is much smaller than the density of its host black hole.
Only in the sense that the solar system is part of the milky way.
Halley's comet is part of the Milky Way. Although it moves very far out from our solar system, it never leaves the Milky Way.
The Milky Way is the galaxy in which our sun is located. The local group of stars is part of the Milky Way and therefore smaller than it is. The local Group of galaxies is a cluster of galaxies and therefore larger than the Milky Way.
No. It is possible for a comet to leave our solar system, but not the galaxy.
they all are in space?
It's theoretically possible for a black hole to be larger than the Milky Way, but as far as we know, most are much, much smaller both in mass and extent.
No - many orders of magnitude SMALLER
No; there is only one Milky Way.
Neither ! It's a galaxy !
No. The local group contains the Milky Way and a few other galaxies.
The Large and Small Magellanic Clouds, which are 2 small galaxies orbiting the Milky Way.The Andromeda Galaxy, which is slightly larger than the Milky Way.The Triangulum Galaxy, which is slightly smaller than the Milky Way.
