What is the difference between the sun and other stars?

Our sun is solidly in the average category. The exact average star is about 1,000,000 miles in diameter.\n\nMany other stars are spectacularly larger or smaller.\n\nThe lifespan of larger stars is shorter.  Srars become brighter at the end of their life, when hydrogen nuclei have been exhausted.  \n\nWhen stars become supernovae, other elements are created, the last one being iron, and much material is blown off.\n\nThen you have a dying monarch of light.  Red and white drwarfs.\n\nSites for stellar evolution info:\nhttp://search.yahoo.com/search?fr=ks&p=stellar+evolution\n\nOur sun has a remaining life span at current luminosity of 25 billion years.  That should give us enough time to figure out what to do when it goes into the ending processes.\n\nDetailed information about our sun and neighborhood:\nhttp://www.urantia.org/papers/toc.html\ngo to Paper 41 and Paper 57

As all the others said, the sun is a star, and you see it every day. Sometimes, in early morning or in late afternoon, some of the most prominent start may be visible, mostly on the horizon.\n\nAll the stars which you can see by night is still there during the day, but the sun's light is so bright that we cannot see past its brightness to where the stars are.\n\nI once heard in an astronomy class that it is able to see a star in the day, but the light of the star has to fall directly in the mid-center of your eye, and that takes some doing.\n\nLastly, there are certain occasions where stars are visible during the day. I remember when I was in primary school, the Planet Venus (although not a star) was visible next to the moon right in the middle of the day. If Venus can be visible at that time, then why not any other star?\n\nHope I could help you...

There are a lot of red stars in space. From Nasa's web site: "There are many normal red stars near the Sun, with temperatures of a few thousand degrees and masses much less than that of the Sun. None, however, is bright enough to be seen without a telescope. All of the bright red stars in the night sky are red giants and supergiants, counted among those we term abnormal stars. Examples are the supergiants Betelgeuse in Orion and Antares in Scorpius (each about 520 light years from Earth) and giant Aldebaran (68 light years) in Taurus."

There are many differences.\n\nBy the wording of your question, it sounds like you are speaking about the movement of celestial bodies.\n\nMost stars (except the sun, seem to stay in the same position in relation to one another.  The sun, moon and   the planets, change their position against the background of the "fixed" stars.  \n\nThis is because the objects in our solar system are close to us, so their change in position is much easier to see.  The fixed stars are so much further away, that their motion is harder to detect.\n\nThis is similar to the experience of riding in a car.  If you look at a distant mountain,  the appearance of it doesn't change very quickly.  But as you come close to a street or a building, the appearance changes dramatically. \n\nThe reason is that if you measure apparent motion by an angle,  an object twice as far from you must move twice the distance across your Field of vision to have the same apparent motion.

Stars emit their own bright light, so to our eyes it looks white. Moon reflects the sun rays, so the easiest colour of light absorbed and reflected is white. That is why.

No. \n\nStar:\nA self-luminous celestial body consisting of a mass of gas held together by its own gravity in which the energy generated by nuclear reactions in the interior is balanced by the outflow of energy to the surface, and the inward-directed gravitational forces are balanced by the outward-directed gas and radiation pressures\n\nPlanet:\nA nonluminous celestial body larger than an asteroid or comet, illuminated by light from a star, such as the sun, around which it revolves.\n\nSo, stars are self-luminous (have their own light) and are stationary. Planets don't produce their own light and revolve around a star.

All different colors.  Their color depends on the temperature of the star.  A cool star will look red, a hot star will look blue, the sun looks yellow because it's somewhere in the middle.  You get the same colors when heating things.  Red flame is cooler then blue flame.

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

If the sun were part of a binary system, it would revolve around the barycenter of the binary system. We would be able to dected this movment by comparing the Sun's position to other nearby stars and to more distant stars. Since we don't dectect any such movement around the barycenter, that means that any such compainion star must be very very small, making the barycenter close to the sun's positon, or very far away, making the motion of the sun about the barycenter very slow. \n\nNeither of these conditions are true of any other binary star system we see, so no.

The sun has lived for a long time actually the sun isn't alive but anyway stars usually live for a bout ten billion years.  they know this by looking at the history of other stars and how much they have gone out in the short amount of time  it was being studied. The sun is burning its hydrogen gas so its not a really accurate guess but its pretty close. but you wont have to worry about the sun burning out because you will already be dead for a long time.

sun....its a star btw but there are stars bigger than the sun

in actual fact the SUN is a star. The other STAR/STARS are not called sun because they are extremely far from us and have no quite any uses to us but the sun id use ful to us by providing heat. So i guess the people are trying to make the SUN a special star by giving it a different name.\nlol...

well stars are in real more like our sun which gives heat and light, but y they have diff color id coz AS ALL THE STARS ARE NOT AT THE SAME DISTANCE FRM THE EARTH THE LIGHT WHICH TRAVELLS FRM THEM AND REACHES US GIVE THEm COLOR .\n\nLIKE white light has 7 colors in it and each has different wave lenght which means that their light travels on those wave lenghts, and secondly the air in our atmosphere water particles are suspended always and these light passing through them give different wave lenght wch gives us diff color

Okay, everyone else so far is WRONG. The sun, like any well-behaved (approximate) blackbody, does absorb light which impinges upon it. A good illustration would be if the sun were part of a binary star system and it's companion star were 20x brighter. When you are positioned such that all of both stars were visible to you, things would be quite bright and you'd be wishing for some SPF 10,000. Now, if the sun moved in front if it's brighter companion (from your point of view), the total amount of light you see from the binary system would be reduced by a factor of around 20 because you would be in the SHADOW of the sun with respect to the brighter star... in other words the sun itself, although it is a light source, would be shading you from it's brighter companion because it does absorb light. I hope this helps.

All stars except the Sun appear to the human eye as shining points in the night sky that twinkle because of the effect of the Earth's atmosphere. Interferometer telescopes are required in order to produce images of these objects. The Sun is also a star, but it is close enough to Earth to appear as a disk instead, and to provide daylight.\n\nStars are not spread uniformly across the universe, but are typically grouped into galaxies. A typical galaxy contains hundreds of billions of stars. The majority of stars are gravitationally bound to other stars, forming binary stars. Larger groups called star clusters also exist.\n\nAstronomers estimate that there are at least 70 sextillion (7×1022) stars in the known universe [1]. That is 70 000 000 000 000 000 000 000, or 230 billion times as many as the 300 billion in our own Milky Way.\n\nThe nearest star to the Earth, apart from the Sun, is Proxima Centauri, which is 39.9 trillion kilometers, or 4.2 light years away (light from Proxima Centauri takes 4.2 years to reach Earth). Travelling at the orbit speed of the Space Shuttle (5 miles per second -- almost 30,000 kilometers per hour), it would take about 150,000 years to get there. Distances like this are typical inside galactic discs, where the Sun and Earth are located. Stars can be much closer to each other in the centres of galaxies and globular clusters, or much further apart in galactic halos.\n\nCheck the wikipedia link below.

It's going to be difficult to tell you more than I know, but I'll give it my best shot.\n\nThe sun is big and bright and hot.  It is a giant fusion reactor creating energy by fusing atoms of matter together.  The energy is transmitted out into space as photons of light.\n\nIt is a medium sized yellow star which began making energy about 4 billion years ago and is estimated to have about 5 billion years left before its fuel begins to run out.
