are  each  star a sun and  if  so  do they  hav  planets  around  them ?

This has been pretty well answered but I thought I'd clarify.\n\nThe Sun is the name of our solar system's star, the star we call home.  (Similarly the Moon is technically the name of Earth's only natural satellite, other planets have natural satellites which we commonly call "moons").  Other stars have different names (like Vega).\n\nWe are just finding extrasolar planets (planets that orbit other stars) and it is likely that there are many stars out there with planets and even solar systems (more than one planet orbiting them).  However it is also very likely that many stars will not have any planets at all.\n\nIf you are interested in this, here is a fun website about extrasolar planets: http://planetquest.jpl.nasa.gov/index.cfm

Stars are big fiery balls of gas. Essentially the gases cluster together and become stars through gravity and fusion. It's a rather complicated process; check the link below for a more detailed explanation.\n\nStars appear to be in our sky because they are in space. Most stars appear to be small points of light, although many of these stars are smaller than our sun. The sun simply appears larger because it is much nearer to the Earth.

Stars (our Sun included) form inside large nebulas of gas and dust in space.  A single nebula forms tens to hundreds of stars, so our Sun did form with other stars.  The stars that form together in a nebula eventually go there separate ways, so to speak, but systems of two, three, or more stars are quite common.\n\nHere's a nebula where stars are forming right now:\nhttp://www.seds.org/messier/m/m042.html

Right now, Farlack of the Geltrans on Planet Flibbering, orbiting the Dog star of Mecaea is asking the same thing of his peers on their version of the internet.\n\nBut seriously... all those stars... billions of them are all suns.  If only half of them have a few planets revolving around them, one of them has to have life on it.

There are about a couple hundred billion stars in our galaxy. The stars close to the center are not likely to have planets because of dynamical considerations (other stars pass by too frequently to have stable orbits).\n\nThe BIG question is how many planets there are per star on average. Our sun has ten planets and assorted other objects. We have found many other planets orbiting other stars, but most of those stars have only one planet (that we have detected). One has three planets that we know about. HOWEVER, the way we detect these planets favors detecting large planets that are very close to their star. Once you start to ask about planets as small as Saturn, or that are farther away than Mercury is from our sun, the methods don't work so well.\n\nThe upshot is that we really just don't know how many planets a typical star has. Some probably have none. How many have none? We don't know. How many have ten smallish planets? We don't know. At best we can guess, say 4-5 on average. This would give close to a trillion planets in our galaxy. The number could easily be a tenth of this, though.

planets orbit stars, satellites orbit planets

It is not a star but a planet which you can tell since it is not twinkling. Stars are so far away they appear as a point, while planets have a observable disk. Wind in the upper atmosphere then causes the light to bend which causes star light to twinkle but planets do not. \n\nOnce you determine it is a planet because it is not twinkling. You can rule out it being venus since it is too far from the sun. Venus is also usually a bit brighter.\n\nNow it is too bright to be Saturn or certainly any further planet. That leaves Jupiter or Mars. These you can distinguish by color. Mars has a reddish tinge to it. What you are observing does not.\n\n It is Jupiter. If you have a good pair of binoculars you should even be able to make out a couple moons.

If you mean our Solar system (there's other suns with planets revolving around them) then our Solar System is in our Galaxy...The Milky Way.

Our sun is indeed a star. As a star,it will go through all the phases that other stars go through like BIG BANG and etc. Yes,our sun will explode one day and that day will be in another million or billion years of time. So,don't worry about it now. Worry about your great grandchildren. Anyway i hope that i had answered your question. Take care.

Planets do not twinkle the way stars do. In fact, this is a good way of figuring out if a particular object you see in the sky is a planet or a star. The reason is that stars are so far away that they are essentially points of light on the sky, while planets actually have finite size. The size of a planet on the sky in a sense "averages out" the turbulent effects of the atmosphere, presenting a relatively stable image to the eye.

yes. All The gas giants in our solar system have ring systems. Even uranus. neptune's is very faint and hard to see.

Our solar system now has eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.\nThey are arranged outward from the sun as I've listed them.\nThat is with Mercury closest to the sun.\n\nWe also have three "Dwarf Planets"\nCeres, Pluto, and Eris.\nCeres being closest to the sun.

The sun is a star. When it becomes a red giant the earth will be vaporized. thats a few billion years off but it will happen. So yes it does.

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.

You've almost answered your own question:  Stars are "stationary" sources of energy (nuclear) and give off light.  Planets do not and they orbit stars.

It is estimated that there are approximately 200 million stars in the Milky Way and each one has the potential to have a "solar system" of some type.  Depends on many factors and the type of planets that can exist around a particular star also have many factors.  A number of "solar systems" have been found around other stars.  A current list of them can be found at exoplanets.org

Is the sun a planet?  Is the moon a star?  Is the earth yellow and full and made of cheese?
