The revolution period of the sun around the milky way galaxy I mean.
2006-07-16 09:31:13 · update #1
The Sun's trip around the core of the Milky Way takes about 225 to 250 million years. Its distant to the core also varies with time. There was a place on the Internet that showed an animation of its orbit. Wish I could find it again. Given its age, the sun has been around the galaxy core perhaps 20 times since it was first formed. With its current position, the solar system is about 26,000 light years from the center of the galaxy.
Since I was born, the sun has move a mere 340,000,000 miles along its orbit.

The Sun completes 1 revolution around the Milky Way once every 225 million years. The period of time is called a cosmic year.

Unlike Earth which rotates at all latitudes every 24 hours, the Sun rotates every 25 days at the equator and takes progressively longer to rotate at higher latitudes, up to 35 days at the poles. 25 days would be .068 earth years, and 35 days would be .096 years.
Oh, it looks like you changed the question to ask about revolution around the galaxy. The Sun makes one complete orbit around the galaxy about once every 225 million years.

the sun orbits the center of the Milky Way once every 225 to 250 million years.

the center of the galaxy is a very interesting place. we can't see the center because of dust in the clouds surrounding it, but we can observe the center in infra-red wavelengths. the radio source at the center is called sagittarius a* (spoken "a star") there is a supermassive black hole at the center. it is about 2.6 million solar masses.

The sun rotates once every eleven (11) years, but revolves once every 250 million years, or something like that.

It rotates about itself in about thirty days. As to circumventing the galaxy I think the estimate is about 80,000 years but don't quote me.

The sun doesn't revolve...it's a giant ball of gas.

doesn't it revolve? why shouldn't it? everything else in this solar system does, except moons, and they have an excuse.
