Anybody knows how many planets are still there in our "EARTH'S Solar System"?
828916
8 - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.  Almost assurdly there are no more big ones.  There are also a class of planets called "dwarf planets", including Pluto and a couple of others.

Over 2 years ago, scientists DID find a 10th planet beyond Pluto, and it's even larger than Pluto. The planet is a typical member of the Kuiper belt, but its sheer size in relation to the nine known planets means that it can only be classified as a planet. Currently about 97 times further from the sun than the Earth, the planet is the farthest-known object in the solar system, and the third brightest of the Kuiper belt objects. \n\nFor images and info, check the NASA web site: http://www.nasa.gov/vision/universe/solarsystem/newplanet-072905.html

The astrobiology folks at NASA have calculated that there are between one and thirty billion habitable planets in our Milky Way Galaxy.  If our solar system is typical,  you can multiply that by about 10 to get total planets: between 10 and 300 billion.  \n\nSo where is everybody?

we already found a 10th planet in our solar system, but it's still unclear if it's considered as planet (some say it is too small).\nThe name of the "10th planet" is Sedna.

There are still 9 according to the latests NASA reports. Although it has been found that there are several other small objects orbiting past Neptune that are similar in make up and size to Pluto- that pluto's categorization of planet will not be changed. That instead a number system is being talked about to go into effect that will number the bundles of pluto-like objects. Though again, pluto would not be changed. (First Source)\n\nIf it weren't for the stubborn desire to keep tradition- Pluto WOULD NOT be considered a planet, it just does not have the characteristics to make it one. But because tradition is very important in this society- Pluto remains a planet for now.

With over sixty three moons to date and growing, Jupiter has more moons than any other planet in the Solar system*.  In fact, Jupiter and its moons are often referred to as the Jovian system (Jove being an alternate name for Jupiter), and are almost more complex as a planetary system than the Solar system itself is.\n\nThe planet with the second most numerous moons is the planet Saturn.  If you would like more information on either the moons of Jupiter or Saturn, I would highly recommend searching through either nasa.gov, nineplanets.org (which can be a little dry but still has a lot of useful information), or solarviews.com.\n\n\n*By the way, there's only one "Solar system" since the name refers to the star in the center of our star system, which is properly named "Sol", and not "the Sun"... all other systems containing a star and planets would be properly referred to as either a planetary system or a star system, as they do not orbit the star Sol.

yes.there is entirely a newly discovered solar system.there are 3 planets,all revolving around the star upilisone androemedae,and all of them are bigger than jupiter!and NASA has sent satellites which will go to pluto and beyond.hope we find the answers then!

There is only one solar system, and it is the one our planet is part of.\n\nThe solar system comprises the Earth's Sun and the retinue of celestial objects gravitationally bound to it. Traditionally, this is said to consist of the Sun, nine planets and their 158 currently known moons; however, a large number of other objects, including asteroids, meteoroids, planetoids, comets, and interplanetary dust, orbit the Sun as well. Astornomers are debating over the presence of a tenth planet.\n\nAlthough the term "solar system" is frequently applied to other star systems and the planetary systems which may comprise them, it should strictly refer to Earth's system specifically: the word "solar" is derived from the Sun's Latin name, Sol, and thus the term sometimes appears as Solar System. When talking about another stellar system or planetary system, including the stars and bodies associated with them through gravity, it is usual to shorten it to drop the term "stellar" and form names such as "the Alpha Centauri system" or "the 51 Pegasi system".

Our solar system is not the only solar system in the universe.  There are hundreds and thousands and millions of other planets in the universe, and many are just like ours, but we don't know about them because we have never been able to get anything further than pluto to get a good specific picture of stuff.  In a general picture, though, we do know there are other galaxies in the universe

There have been no planets added to the current list of nine in our solar system.  There have been several planets found around a number of nearby stars but those are not associated with our solar system.  To get a list of those go to exoplanets.org.\n\nThere have been a number of recent discoveries of object near or at the edge of our solar system.  These can have any number of names such as trans-Neptunian object, Kuiper Belt object, inner Oort cloud member, among others.  These are not planets.  They simply do not fit the criteria necessary to be called a planet but more importantly they have not been designated that title by the official naming authority for professional astronomy, the IAU.  \n\nThese objects resemble Pluto in some aspects but we actually know very little about them because they are so distant and small.  Among the more notable of these discoveries are Sedna, Xena and Quaoar.  They are small icy, rocky bodies that are believed to have changed very little since they formation 4.5 billion years ago whenthe solar system formed.

there hasn't been any found yet.... but... the possibility of life on other planets is very  high....  :)

Sol (our solar system) consists of 9 planets, over 140 moons (to date) and several small cosmic objects (comets and asteroids).\n\nMercury (0 moons)\nVenus (0 moons)\nEarth (1 moon)\nMars (2 moons)\nJupiter (63 moons as of 2004)\nSaturn (34 moons)\nUranus (21 named moons, 6 unnamed moons)\nNeptune (8 named moons, 5 unnamed moons)\nPluto (1 moon)\n\nThere have been discoveries of more "planetary objects" beyond Pluto, but they have not been declared to be planets in the same sense as the others.

The simple answer is we don't know..... we're still developping the technology to find them.\n\nOf the estimated 70 sextillion stars in the known universe, (that is 70 000 000 000 000 000 000 000, or 230 billion times as much as the 300 billion in our own Milky Way Galaxy), we've only found about 180 - 190 Planets outside our own Solar System so far... and that's only indirectly with only one seen so far (using an Ifra-Red telescope or something).

Unfortunately we do not have any concrete evidence.  Here is a good quote by the late Carl Sagan:\n\n"There are some hundred billion (1011) galaxies, each with, on the average, a hundred billion stars. In all the galaxies, there are perhaps as many planets as stars, 1011 x 1011 = 1022, ten billion trillion. In the face of such overpowering numbers, what is the likelihood that only one ordinary star, the Sun, is accompanied by an inhabited planet? Why should we, tucked away in some forgotten corner of the Cosmos, be so fortunate? To me, it seems far more likely that the universe is \nbrimming over with life. But we humans do not yet know. We are just beginning our explorations. The only planet we are sure is inhabited is a tiny speck of rock and metal, shining feebly by reflected sunlight, and at this distance utterly lost."

You've awakened the starry-eyed dreamer in me at this late hour!  I should be sleeping, but can't resist your question.\n\nHow many other planets, do I think?  Actually my number is a lot higher than millions!  In fact, on this subject you get into numbers so large that most of us humans cannot relate them to anything in our experience.  So, sadly, I doubt we can appreciate the grandeur of the universe.  But let me try...\n\nOne fairly recent estimate says there are 70 sextillion *visible stars* in range of modern telescopes (70,000 million million million).\n\nTo help put that in perspective, I'll use a rather old but useful analogy.  Imagine scooping up a big handful of sand at the beach. Try counting the grains of sand.  You'll give up, most likely, in seconds, assuming you even bother to try.  Now look all around you on the beach, and think about *that* number.  Now think about all the grains of sand on *all the world's* beaches... and deserts.  Now multiply that total number by ten, and you get approximately the number above -- of stars in the *known* universe.  The stars not visible to us by even our most powerful telescopes may equal the visible figure -- or be multiples of it.  Mind-boggling, no?\n\nSo to your planet question:  One next has to wonder how many of those stars are actually a sun to one or more planets (hey, I just noticed that was your wording, too; I like it).  Does every star have at least one planet revolving about it?  \n\nWell let's just be very conservative and say that there are only 70 sextillion stars in the *entire* (not just known) universe.  Let's further say that only one tenth of those stars (7 sextillion) have a planet orbiting them.  If we assume merely one planet per sun, then there must be at least 7 sextillion planets in the universe.  Using our sand analogy, that's a planet per grain of sand on all the world's beaches and deserts!\n\nAnyone who believes that is a reasonable number must surely wonder, "How could there NOT be living beings somewhere other than the earth?"  \n\nOf course not all planets will have life on them.  Earth may be the only body in our solar system, for example, which does harbor life, though at least one of Jupiter's moons is also a tantalizing possibility.\n\nIf only one out of a *thousand* of those planets are earth-like -- in the sense that they are rocky, not gaseous, and contain liquid water -- there may be 7 quintillion earth-like planets in the universe.  That's 7,000 thousand trillion.  I've been very careful, but if my math or estimates are off by even a factor of a *billion* there could be 7,000 million earth-like planets in the universe, a figure I think is extremely low.\n\nThese figures seems to jibe fairly well with an estimate of the number of earth-like planets in our galaxy alone, found at space.com (the bottom link in my sources) -- 30 billion, from a 2002 article.\n\nMy personal belief, based on numbers such as this, and on the likelihood that any planet supporting life may contain (extremely conservatively!) a thousand species...  is that there are *billions* of intelligent species in the universe outside the earth.\n\nSince you were wise to point out that we reside in the Milky Way galaxy, which is only one of perhaps billions of galaxies, you might be fascinated by the Hubble photo in the references, below.  I liked it so much, myself, that I made it my new desktop wallpaper.\n\nFinally, on the specific subject of life, there is a well-known method of estimating the number of intelligent, communicating civilizations, called the Drake Equation.  In my references you can see how it works to condense all the possible stars down by multiple factors, leaving the fraction which we may be able to communicate with, or at least hear from!  \n\nHappy dreaming (for me, too), and I hope you are as inspired by all this as I am.   :-)
