SOLAR SYSTEM

Detailed explanation-1: -We all know that black holes are the most massive objects in the universe. They are able to swallow entire star systems without batting an eye (black holes don’t have eyes, but if they did, we bet they could swallow star systems without batting them).

Detailed explanation-2: -Typically about 80% of the mass in a galaxy is in the form of stars and most of the rest is gas. (In addition, galaxies are inferred to have halos of dark matter of unknown composition containing much more matter, perhaps ten times more.)

Detailed explanation-3: -Dark Energy The most abundant mass of the universe is not dark matter or stars or galaxies or clouds of gas and dust. It’s something called “dark energy” and it makes up 73 percent of the universe.

Detailed explanation-4: -Much of the mass of the Milky Way seems to be dark matter, an unknown and invisible form of matter that interacts gravitationally with ordinary matter. A dark matter halo is conjectured to spread out relatively uniformly to a distance beyond one hundred kiloparsecs (kpc) from the Galactic Center.
