How many planets are there in our solar system?
86735
Well... Pluto isn't exactly a planet... some people speculate it is... others don't. Yes, another one has been discovered a while ago... I think it was Planet Nebula or something... in the far away galaxy of Cygnus (the constellation that resembles a goose)... You are talking about our solar system... right? I thought as much. In our solar system... there'd be 8 or 9, depending if you call Pluto a planet or not.\n\nEDIT: OK... there was one mass that could be considered a planet found in our solar system. It was called Ceres or something... found between Mars and Jupiter. Pluto may be an asteroid!

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.

There are definetly more than nine planetes in the solar system.There are many discovered by scientists and many more are yet to be found. And it is suggested that there are many more solar systems in the milky way.

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.

In our Solar System, there are eight official planets, nine if you count Pluto (whose status is being debated).  \n\nAs for the rest of the universe, it is difficult to say, but it is reasonable to assume that planet formation from leftover stellar material is relatively common.  Astronomers usually detect large gaseous planets (like Jupiter) by the slight wobble of the star's motion due to the gravity of the planet, so currently it is almost impossible to detect small planets.\n\nAs of November 2005, there were 164 confirmed extrasolar planets.

We're still working on trying to find planets, and so far are up to about 100 for sure. Finding moons around those planets is something that's currently beyond us, but it's likely that many of them do have moons. In a galaxcy our size, there could easily be trillions of planets with trillions of moons, but we have no way to know at present.

Jupiter is just the largest planet in our solar system-that's like saying uncle Joe in the largest person who ever lived, cause he is the largest person in the family!  We have already identified over a dozen planets much larger than Jupiter in other solar systems.  We havent even identified all the galaxies in the universe (each of which contains around 100 billion stars, each star of which may contain 10 or so planets), let alone seen all the planets there are..

Please make a distinction between the solar system and the Milky Way. The solar system consists of the sun, and the planets, asteroids, and comets orbiting the sun. There is one star in the solar system (the sun). The Milky Way is our galaxy and consists of billions of stars and presumably whatever planets, etc. orbit those other stars. The difference in size is quite considerable. If the solar system was only 2 yards across, the Mily Way would be 100,000 *miles* across.\n\nThe planets in our solar system are (in order from the sun) Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, and Xena (unofficial name...may become Sedna). Most asteroids orbit between Mars and Jupiter, but not all of them.

There are 192 member countries recognized by the United Nations, and 193 recognized by the state department of the U.S. There are currently 9 (the number is disputed) planets if you count Pluto and 8 if you don't, but that is just in our solar system. There are a lot more planets out there.

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!

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.

Even though we can't prove it, the answer is yes. The universe has billions upon billons of stars. So even if our planet was like 1 in a billion, there still would be 8 or 9 other planets like ours. How advance the civilization is, we cannot tell. This is in reference to intelligent life. As far as microscopic life, there well may be signs of this in our own solar system. Scientist at NASA have recently discovered liquid water under only tens of meters of ice on one of Saturn's moons. Along with this, they also discovered a thermal heat source at it's south pole, which is spewing water 300 miles into space. So this heat source and water may be home to microscopic organisms that have adapted to the cold of the moon. Hope this helps.

The last time I checked there were still 9 planets and they were considering maybe adding a 10th. Pluto is a planet with a moon of it's own named Charon. Astronomers have also identified a couple of other large bodies orbiting beyond Pluto. It has been suggested that there could be two planetoids beyond Pluto that revolve around each other.

They aren't.  Of the nearly 200 stars that have been identified as having at least one planet, about fifteen are known to have more than one planet, including 55 Cancri, which has at least four..Our current problem is just being able to identify planets much smaller than Jupiter, although one about the size of our Moon has been identified as part of a system in orbit around a pulsar.  For a complete up to date list, go to wikipedia and enter "exoplanets" in the search box.\nYou may have been confused by some theories that stars with Jovian sized planets in very close orbits may not have more distant planets, but that has nothing to do with stability, and seems to be wrong anyway.

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

Right now there are officially 9.  Depending on what we decide in the next year or so that number will change to 8, stay 9, go to 10, or even larger.  An object larger than Pluto has been found, but we have not granted it official status as a planet.  Don't expect this issue to be resolved any time soon, we've more or less "tabled" the issue until our general meeting in August.
