Cluster- a group of stars or galaxies forming a relatively close association.
<span>Constellation- A group of stars that makes a shape, and has a name that is well known.

<span /><span>Solar system- a system of planets revolving around a center, or sun.
</span>
Universe- the whole wide range of galaxies, stars, and solar systems that were ever formed.
The best answer would be "Cluster" because the universe is infinite, they are millions of galaxies, solar systems, and constellations in it. The question only states 'a thousand galaxies'. This is of one kind. This best works for the question.
I hope this helps!

To solve this problem it is necessary to apply to the concepts related to energy conservation. For this purpose we will consider potential energy and kinetic energy as the energies linked to the body. The final kinetic energy is null since everything is converted into potential energy, therefore
Potential Energy can be defined as,
Kinetic Energy can be defined as,
Now for Conservation of Energy,
