A Galaxy Group: Is the smallest grouping and usually contains less than 50 galaxies.A Galaxy Cluster: Is larger than a group and usually contains between 50 to 1,000 galaxies.A Supercluster: Is the largest collection of galaxies and will contain many groups and clusters.I think you mean group of galaxies. A group of galaxies is groups and clusters are the largest known gravitationally bound objects to have arisen thus far in the process of cosmic structure formation. They form the densest part of the large scale structure of the universe.
A binary star.
Two stars that are gravitationally bound to each other are sometimes called "binary stars".
A star is all that's required. A solar system is made of at least one star, and the star has to be big enough to have gravity strong enough to bring other objects such as gas and rock and ice into it's orbit.
No, a pulsar is not a part of the solar system. Pulsars are highly magnetized, rotating neutron stars that emit beams of electromagnetic radiation, while the solar system consists of the Sun, planets, and other celestial objects that are gravitationally bound to the Sun.
its the universe with our planets and moons in it
There are currently no known means to actually separate parts of the universe physically from the rest of the universe.
A massive gravitationally bound system typically refers to a structure in the universe where a significant amount of mass, such as galaxies or galaxy clusters, is held together by gravitational forces. This binding occurs when the gravitational attraction between the constituent objects is strong enough to overcome their kinetic energy, preventing them from drifting apart. Such systems can include galaxies, star clusters, or even larger structures like superclusters, which play a crucial role in the large-scale structure of the universe.
I am not quite sure what you mean by "independent". It is gravitationally bound to our galaxy (the Milky Way); that is, it rotates around the center of the Milky Way.
Every particle of matter in the universe is in the sun's gravitational 'field', althoughit may not necessarily be gravitationally 'bound' to the sun in a closed orbit. Thegravitational force that attracts two masses to each other is never zero, no matterhow far apart they are.That means that every particle of matter in the universe is also in the gravitationalfield of you.
They are bound to the sun in closed orbits by mutual gravitational attraction. Those that had too much kinetic energy to be captured and gravitationally bound to the sun, weren't, and they're gone.
The noun galaxy is a collective noun for a galaxy of planets or a galaxy of stars (both celestial and cinematic).

All the superclusters we can see compose the large-scale structure of the universe, forming a vast network of galaxy clusters and groups. These superclusters are interconnected by filaments of dark matter and gas, creating a web-like structure known as the cosmic web. They represent the largest known gravitationally-bound structures, playing a crucial role in the distribution of galaxies and the evolution of the universe.
When objects are bound gravitationally in centrifugal motion, the objects are said to be in orbit of each other.
