There is nothing outside the Universe that could orbit it. Suns orbit the centers of galaxies. Planets, asteroids, comets, etc. orbit around stars.

Actually, nothing is beyond the universe, therefore nothing can orbit it. This is applicable even more strictly if u are talking bout the galaxies and/or stars within our universe.
Otherwise, the galaxies are not orbitting around anythin. Imagine them as dots placed on a rubber sheet. Then, if u stretch the rubber sheet, the dots will move further apart. Similar kind of motion is exhibited by galaxies. (as the universe is expanding continuously)
For stars, they may be of two types-
1. IN A GALAXY
these stars are present in the galaxy, and move with the galaxy. ex- Sun. Its just like the moon is orbitting the earth as well as the sun(i mean the earth moon system orbits around the sun, so in a way i can say that the moon also orbits around the sun)
2.OUTSIDE THE GALAXY
these stars may be ejected out from a galaxy, and they do not reli orbit around anything. They may juz wander in inter-galactic space or may be gulped by another galaxy.

Nothing in orbital motion around the Universe. There is nothing outside the Universe.
The star on our solar system (the Sun) is in orbital motion around the center of our galaxy. Our galaxy itself is not orbiting around anything.
