Nobody has any idea. Several hundred have been identified. But it's a hugely difficult process, and more keep being discovered all the time. It's beginning to look like most stars have planets, and nobody is even sure of how many STARS there are in the Milky Way Galaxy, because some of THEM are so hard to see..
Ah, what a wonderful thought to ponder! Our star, the mighty Sun, is recognized as a G2V type star in the grand spaciousness of our beautiful galaxy, the Milky Way. It graces us with its warm presence and provides life-giving energy to our celestial environment. Trully marvelous, right there.
Moons orbit planets. Planets orbit stars. Some stars orbit other stars, or orbit their mutual center of gravity. Stars orbit the center of the galaxy. Galaxies may orbit the center of the "galactic group".
Gravity causes all orbits. It is believed that there is a "super massive" black hole at the center of the Milky Way, and most or all other galaxies, that serves as the primary source of gravity.
To find the Milky Way in the night sky, head to a dark location away from city lights. Look for a faint band of light stretching across the sky, which is the Milky Way. It is best seen during the summer months in the northern hemisphere and winter months in the southern hemisphere. Use a star map or a stargazing app to help locate it.
Gravity and inertia are the two forces that act on all matter in the universe. If there were only two stars in the universe and they were standing still, the force of gravity would cause them to eventually fall together and collide. But there are hundreds of billions of stars in the Milky Way alone, and billions of other galaxies out there, and NOTHING is standing still; everything is in motion. The primary forces that keep the stars from falling together is the rotation of the Milky Way; all the stars appear to orbit the center of the Milky Way.
Gravity - nothing more, nothing less
If there was no force then there would be no balance to keep things in place
Well, the forces that keep it in place are gravity and friction. You pretty much answered the question yourself.

Gravity is the force that keeps all things in our universe in place. Enstien theorised that gravity and time were intertwined in to a "fabric".
Forces essentially cause everything in the universe. The combination of magnetic, electric, and gravitational forces explain how stars are born and die as well as how you can move.
What a great question! The Milky Way galaxy, of which the Sun is a part, has approximately one hundred billion stars. Keep in mind that stars and being created and destroyed all the time. As to how many galaxies there are, and a rough estimate of how many stars, it is hard to say because not all of the universe, such as it is, has been observed, and hypotheses vary wildly, so any guess is probably not helpful.
We aren't sure. The bigger the star, the brighter it is and the easier it is to see. On the other hand, dwarf stars are quite dim. The nearest star to our Sun is Proxima Centauri, a red dwarf at a distance of 4.2 light years. Even though it is the CLOSEST star, you cannot see it without a telescope!There does not appear to be enough mass in the Milky Way galaxy to keep it together, and various explanations of the "missing mass" have been suggested, from "dark matter" to a massive black hole at the center of the Milky Way. I wonder if perhaps there might be vast numbers of undetectably-dim dwarf stars scattered throughout space.
Our Sun is pretty much average. It's larger than about 60 to 70 % of the other stars in the Milky Way; the estimate increases as we keep discovering more and more very small and very dim brown dwarf "stars" (that are right on the boundary between "star" and "not star").

Tension force is present in stretched strings, ropes, and cables. This force is caused by the pulling or stretching of the material, creating a force that acts along the length of the object to keep it taut or in place.
