Does the Milky Way revolve around anything?
Does the Milky Way orbit around anything? If so, what's its orbital period?
What's the Milky Way? What is the Milky way? What is the Milky Way? Where is the Milky Way Galaxy? Do all planets have to orbit a star? What is the Milky Way Galaxy? What is outside the Milky Way Galaxy? What astronomical object has the longest orbital period? Why do planets orbit stars? Does a planetary orbit depend on the sun? Why do all planetary systems orbit stars? Is it possible for a star to orbit a planet?  Has it ever been observed? Why are planetary orbits ellipses? What does the sun orbit? Why is the earth's orbit around the sun almost circular? How close are the planets of our solar system to being in the same orbital plane? Does the sun orbit the earth? Are the orbits of each planets coplanar? Is our solar system native to the milky way galaxy? Do the planets of the solar system orbit on the same plane? How does the orbit of Uranus look like (from the top)? Does the Sun actually move through the constellations? Analysis of data from the COBE survey indicates that the Milky Way is travelling at a certain velocity towards a particular point in the sky. Is it known whether our galaxy is oriented edge-on or face-on as it follows this trajectory? Why do the planets in our solar system orbit along the same plane? Are all planets round and why? What is the molecular orbital? Why are the orbits of planets elliptical? Do we move around the constellations? Is the planet earth moving close to the sun with every orbit? What is the Molecular Orbital theory?
