The hierarchical relationship among the astronomical bodies you listed is as follows:
1.Comet:
A comet is a small celestial body composed of ice, dust, and volatile gases. Comets typically have elongated orbits that may bring them close to the Sun.
2.Solar System:
A solar system consists of a central star (in our case, the Sun) and all the celestial objects, including planets, moons, asteroids, comets, and other debris, that are gravitationally bound to that star.
3.Galaxy:
A galaxy is a massive, gravitationally bound system that consists of stars, star clusters, planetary systems, interstellar gas, dust, and dark matter. Our solar system is part of the Milky Way galaxy.
4.Universe:
The universe is the entirety of space-time, including all matter, energy, galaxies, stars, planets, and everything in between. It encompasses all that exists, including all galaxies, solar systems, and celestial objects.
Therefore, the hierarchical relationship is as follows:
Comet < Solar System < Galaxy < Universe
In this sequence, a comet is part of a solar system, a solar system is part of a galaxy, and a galaxy is part of the universe. Each level in the hierarchy represents a progressively larger and more inclusive astronomical structure.
