Does the sun revolve round an axis? And if so do all stars in the Universe do likewise?

Yes they all do, for the same reason that water swirls when it goes down a plughole; conservation of angular momentum.  A star starts off as a large cloud of gas and dust which clumps together under gravity.  If there's even a little bit of swirling motion, as there always is, in the cloud or the water in the bath, then as it comes closer together the rotational speed increases.  Similarly when a rotating ice skater brings her outstretched arms together.  What determines speed of rotation?  The total angular momentum of the system to begin with.  Your angular momentum about an axis is equal to your speed perpendicular to that axis times your distance from it.  Add that up for each particle in the cloud or water molecule in the bath and you've got total angular momentum.  Two particles moving in opposite directions cancel out, but the chances of a large mass having zero net angular momentum are zilch.

The planets were formed by the same cloud of swirling rocks and dust, so when they came together and formed the planets they were all going the same direction. And actually, since the sun was made from the same stuff, it actually rotates in the same direction, though it is hard to tell because there are no surface details to see from earth without assistance to see the movement of the sun. I think astronomers see the rotation of the sun by watching sun spots. \n\nAnd actually they do not all lie in a flat plane. There is actually a small difference between the orbital planes of each of the planets.

Earth revolves around the sun because the giant nebula out of which the solar system formed was spinning and the angular momentum is conserved, and earth spins because of the initial config. Why it revolves in an ellipse, see this\nexplanation at http://www.mathsnet.net/cabri/feynman.html

Actually, those circles are NOT perfect.  They're slighly elliptical.  This is called the excentricity of the orbit.  \n\nBut, yeah, they are more or less on circles, and that's because they want to go straight forward (inertia) but the pull of the Sun's gravity stops them from goind away.\n\nIt like tieing a ball on a rope and turning it around.  It makes a circle.  Let go of the rope, and it will go on a straigt line.  The rope is the Sun's gravity.

We can see the sun rise and set, and it would be impossible for the sun to revolve around the earth because of the huge difference in math, so the only explanation is that the earth is spinning.\n\nIn reply to the first two replys, the sun is not the center of the universe, it is the center of the solar system. Also, because of the sun's gravity, we REVOLVE, but that has nothing to do with rotation. MOMENTUM is what causes us to not feel the spin/movement, not inertia.

Astrology was first created with the basis that the planets and sun revolve around the earth.  Science has proven that that is not true.  Astrology still holds to that format.\nWhy would anyone believe, that the alignment of the stars, now proven to be incorrect over the years, will prove your daily destiny? \nWhy bother...

The Earth turns one time around in 24 hours and as it does the whole sky seems to turn around the North star. Of course the sky is really not moving at all. The Earth under our feet is turning, but it really does LOOK like the sky is turning! The North star never rises or sets because it is right above Earth's north pole, so as the Earth turns it just stays there in one spot while the whole sky seems to turn around it. Stars close enough to the north star can go around without ever rising or setting. So the sky looks like a big clock, but a 24 hour clock. You may have seen special military clocks that have 24 numbered hours and the hour hand goes once around in a day. It is kind of silly anyway having 12 hours on the clock and making the hour hand go around twice a day. Who made that up?\n\nAnyway, you can use the stars in the sky as your dial and the north star as the center of that dial. Only the dial turns and the hands stay still. Oops, we have no hands! We will just imagine a hand always pointing up and let the dial turn behind it. And there are not really numbers, you have to draw a picture of the stars and write numbers on it so you can compare the sky to it and tell time.\n\nClick the link below for instructions.

Yes many stars ar bigger than the Sun. The Sun is a middle aged small to mid sized star. Some of the really giant stars would even overlap the earth's orbit if they were placed where the Sun is. \n\nRefer the following links for some more info on stars.

Your presumption is entirely likely my friend.  Things in the Universe that have mass and hence gravity, tend to rotate around something else.  All plants spin on their axis, all planets orbit around the Sun, the Sun rotates around the center of our Milky Way galaxy, our galaxy rotates around other galaxies in the local cluster of galaxies, the local cluster rotates around other clusters and so on right up to the Universe itself.

Technically, it is ... just slowly ... the orbits that the planets make around the sun are actually the planets spiralling inward toward the sun ... they will collide with the sun eventually.

If the question is about precession, then wikipedia has an answer:\n\n(The earth's axis undergoes a change in the direction of its axis, very slowly though...it spins like a wobbling top, and if you extend the axis up to the heavens and plotted it over 26000 years, it would trace a small circle in the sky. This is known as precession.)\n\n"The explanation of this is: The axis of the Earth undergoes precession due to a combination of the Earth's nonspherical shape (it is an oblate spheroid, bulging outward at the equator) and the gravitational tidal forces of the Moon and Sun applying torque as they attempt to pull the equatorial bulge into the plane of the ecliptic. The portion of the precession due to the combined action of the Sun and the Moon is called lunisolar precession."\n\nLook up the article in wikipedia with the provided link and you'll have a more detailed explanation along with a detailed diagram (2nd link) showing the circle it traces in teh sky... You can see by the diagram that Polaris will/was not always the north star. At different periods of the earth's history, other stars assumed that role or there was no north star.

The Sun rotates on its axis once in about 27 days. This rotation was first detected by observing the motion of sunspots as shown in the animation to the left. The Sun's rotation axis is tilted by about 7.25 degrees from the axis of the Earth's orbit so we see more of the Sun's north pole in September of each year and more of its south pole in March.\n\n\nEDIT: "the sun doesnt move the plantes revolve around the sun"  Your thinking of an Orbit, the earth rotates on an axis, and so does the sun, the earth circles the sun.

Yes,it exerts gravitational pull and it is due to this gravitational pull all the planets are revolving around the sun in fixed orbits.

The Sun does rotate/turn on an axis by itself, but it also rotates around a huge black hole in the center of our galaxy, and it takes a very, very, VERY long time to complete one rotation.\n\nIt rotates around the black hole with similar principles to that of earth revolving around the sun, and yes, eventually it will be swallowed by the black hole.

Neither, the axis it rotates on is a north-south axis. However, the earth is spinning west to east!\n\nPS I wish people wouldn't say it rotates left or right - its meaningless and incorrect. If you look at the Earth with the North Pole at the top it appears to rotate to the right, but if you look at the Earth with the South Pole at the top it appears to rotate to the left. Use east and west! It rotates to the east!

Are you talking about rotation?  That is when the earth spins on it's own axis... You know how you spin a basketball on your finger?  That is called rotation.  It also revolves around the sun.  I think that all heavenly bodies have a rotation, and they all revolve around something else... everything in the universe is in constant motion.

Stars revolve around the center of the galaxy.\nThe Sun revolves around the center of the milky way galaxy.
