if the earth rotates around the sun, then what does the sun rotate around?

Answer 1

The earth rotates on its axis (spins like a globe).
The earth *revolves* around the sun.
The sun is in an outer spiral arm of the Milky Way galaxy.
Therefore, the sun, along with all the stars and other bodies contained in that arm, revolves around the hub of the galaxy.

Answer 2

If you draw a line between the center of the earth and the center of the sun, both the earth and the sun rotate around a point on that line that is called the center of mass or the barycenter. This calculation can be done for all the planets in our solar system.

"Barycenter
The barycenter (or barycentre; from the Greek βαρύκεντρον) is the point between two objects where they balance each other. In other words, the center of gravity where two or more celestial bodies orbit each other. When a moon orbits a planet, or a planet orbits a star, both bodies are actually orbiting around a point which lies outside the center of the greater body. For example, the moon does not orbit the exact center of the earth, instead orbiting a point outside the earth's center (but well below the surface of the Earth) where their respective masses balance each other. The barycenter is one of the foci of the elliptical orbit of each body. This is an important concept in the fields of astronomy, astrophysics, and the like (see two-body problem)."

Our solar system (including the sun) is part of the Milky Way galaxy. The Milky Way is a spinning (rotating) galaxy. Because of this, the sun is rotating around the center of our galaxy.

Our galaxy is a member of a collection of nearby galaxies called "the local group". We are not sure, but, the local group may be rotating around something (perhaps a giant black hole).

To sum this up, we know of several points that our sun is rotating around. There may be more.

Answer 3

The Earth does not rotate around the sun. The Earth "rotates" around its axis. It "revolves" around the sun. The sun also rotates about its own axis...as it revolves around the center of the Milky Way Galaxy.

Mixing up the terms rotate & revolve is a fairly common mistake.

Answer 4

The rotation of the sun is equal to 25 days.

Answer 5

The fact that the earth rotates around the sun has little to do with what the sun rotates around.

The sun, and the planets, and most all of the minor planets, orbit around the "barycenter" of the solar system. This point is the center of mass of the solar system.

The barycenter orbits around the center of the milky way galaxy.

Answer 6

The earth and the rest of the solar system revolve around the sun. They don't rotate around it. Yes the sun also rotates. Like the planets in the solar system it rotates around it's axis. If you're asking what it revolves around its the center of the milky way like the rest of our galaxy. The Milky way revolves around in a galaxy cluster(a big group of galaxies held together by gravity) called the Local Group. And yes the milky way also rotates around its own axis. Hope u found this very very useful.

Answer 7

Actually, the earth and the sun both revolve around the centre of mass of the system, which is located at a point inside the sun since the sun is so much more massive than the earth. The sun also revolves around the centre of the galaxy

Answer 8

Not rotate revolve. The sun revolves around the center of the galaxy about every 240 million years.

Answer 9

Our sun and its planets are situated in the Orion arm of the great spiral galaxy we know as the Milkyway. As the planets orbit around the sun, so too does the sun move with a rotational velocity around the center of the Milkyway.

Answer 10

confident the solar rotates around the earth and the earth isn't rotating and there are a number of evidences for that. certainly earth rotation theory grow to be placed as the thank you to in basic terms enables calculation
