A Binary star system
A system of stars orbiting a common center of gravity where there is no mass at the center of gravity is known as a Kepler Rosette. Such an arrangement is theoretically possible but is unstable. No such an arrangement has (yet) been observed in the real universe.
All objects in a Kepler Rosette have to have identical mass and exactly the same kind of orbit (differing only in their phase angle) and must be evenly spaced on some multiple value of their phase angle. If the orbit of such a Rosette is eccentric then the system will pulsate in diameter on the period of the orbit.

2 stars orbiting a common center of gravity?
"Binary" stars were once considered rare, but we're discovering more and more of them. Typically, there's one very large star, with a smaller star orbiting around it, but there are a few binaries in which the two stars aren't all that different in mass.
How does gravity affect the stars moon an planets?
Gravity keeps the planets in orbit around the sun and the stars and the stars in orbit around the center of the galaxy. Gravity also holds the stars together against their own internal pressure.
How is the motion of the stars similar to the motion of the sun?
The stars we can see are all within our galaxy (the Mikey Way). In general all the stars are orbiting the center of the Mikey Way.
Do the stars orbit the planets or do planets orbit stars?
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".
How do you determine the Milky Way's mass outside the Sun's orbit?
from the orbits of stars and gas clouds orbiting the galactic center at greater distances than the Sun

What are binary pairs in a galaxy?
That means that two stars are close together, orbiting their common center of mass.
What is the relationship between planets stars and galaxies?
Planets generally orbit around stars. (Some interesting speculations suggest that there may be "free planets" that are not near any star.) Billions of these solar systems orbiting their common center of gravity form a galaxy.
What is the name when two stars are bound together gravitationally and orbit a common center of gravity?
The stars are said to be a "gravitational binary pair"
Can a star also be a natural satellite?
In a sense, yes. There are binary star systems. These consist of two stars orbiting each other, or more properly, orbiting their barycenter, their combined center of gravity. You might think of each of them as the other's satellite.
Does Betelgeuse move?
Yes, all stars move. Betelgeuse is orbiting around the center of our galaxy.

Do the stars orbit the planets or do planets orbit stars?
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".
Do the stars or dwarf planets orbit planets?
No. Dwarf planets orbit stars just like planets do. Stars orbit the center of their galaxy. An object orbiting a planet would be a moon.
Where are the planets found?
Orbiting stars. We know of eight planets orbiting our Sun, and we know of over 300 planets orbiting other stars.
