Quite simply it has more mass. The more mass an object has, the more gravity it will have.
Your category is the answer, that thing is black hole
It is called Black Holes and Revelations
A black hole is an object so massive that light cannot escape its gravity, due to the intense gravitational pull caused by its mass and density.
Yes. We're currently orbiting a super-massive black hole located in the center of our galaxy.
A black hole is a region of space in which gravitation is so strong that not even light can escape found at the centers of galaxies and also as the final stage after the death of very massive stars.
Black hole is a location in space that possesses so much gravity, nothing can escape from its pull. Yes, Super massive black hole is the largest black hole.
Yes, a quasar is a galaxy with a super-massive black hole in its center. The hole being invisible, all light vanishing from the great gravity. The quasar itself, among the brightest, most luminous objects in the universe, is being powered by an accretion disc around the black hole.
A super massive black hole.
Which one?

A super massive black hole.
A black hole.
All galaxy's contain one or up to 2 (that we know of) super massive black holes. these keep all the stars, planets everything together. Everything in the galaxy orbits the super massive black hole. It is also a theory that there is a much larger black hole than a super massive black hole, (about a thousand times bigger) in the centre of the universe.
