Our solar system has nine planets and one star, the Sun. In order from the Sun out, the planets are, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. The following phrase will help you remember the planets in their appropriate order: My Very Educated Mother Just Served Us Nine Pizzas. The first letter of each word is the first letter of the name of a planet. From the Hubblesite. Side note - The small planets are Mercury, Venus, Earth, Mars and Pluto. The giant planets are Jupiter, Saturn, Uranus and Neptune. Edit - You are right, there are many minor planets and the 10th not yet named. Then there's the argument of what constitutes a planet. Quirkie - this is the question the way I saw it when I answered it so I'm not sure what you mean in your comment.

There are at least eight planets in our Solar System (or nine, or more, depending how you define "planet"!) As of March 03, 2006 , there were 164 known planets orbiting stars other than the sun. There are so many known now that there is an encyclopedia of them: The encyclopaedia of extrasolar planets: http://vo.obspm.fr/exoplanetes/encyclo/encycl.html

That depends on who you ask...currently 2003 UB313, otherwise known as "Xena", is being fiercely fought over. It has not been officially accepted as a planet yet, but it cannot be easily dismissed as one since it is significantly larger than Pluto. See http://www.telescopes.com/new-planet/index.php for the perspective of some people who definitely think it qualifies as a planet, if Pluto does. (Incidentally -- it also has a moon, called, of course, "Gabrielle".) (Answers, m'dear, everything in this post is factually correct and independently verifiable. Xena is a possible planet. Its official status has not yet been decided, but it has points in its favor. Get over it.)

Well, in the universe there are millions upon billions which we have not even become aware of...as for our own solar system we are currently aware of 8 planets with 3 dwarf planets....(just until recently it was 9 but since Pluto no longer has that status it has came down to 8)
-
8 Planets; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
-
Impossible to know, as the whole of the universe is yet unexplored and unmapped. If you are referring to our solar system it is 8: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
-
So, who is going to be the first to make a "Uranus" joke? (On a more serious note, I remember Pluto being down-graded recently but I can't remember the reasons for it, if someone would explain that would be just super!)
-
In our solar system, 8. In the universe, there is an infinite number of planets...
-
There are to many to count for.
-
Eight in our Solar System, and a bunch of other "dwarf planets" which is what pluto was demoted to. I dont think anyone will ever find out the number of planets in the entire universe.
-
so far around 250 extrasolar planets have been detected. it seems that the universe is chock full of planets, actually. http://exoplanet.eu/
-
In ours, there are eight. It used to be nine, but Pluto was recently downgraded to being a part of the "Kuiper Belt".
-
With the elimination of Pluto, now a minor planet. There are 8. Mercury, Venus, Earth, Mars, Jupiter, Saturn, (my favorite, pronounced Your Anus) Uranus, and finally Neptune
-
There are only 8 planets since Pluto has been declassified as asteroid.
-
Murcury, venus, earth, mars, jupiter, saturn, uranus, neptune... Pluto is no longer a planet, poor little guy, its descrimination i say, just because he's small for his age...
-
There is 7 in the past but now without pluto there is 6 planets
-
Officially, the number is 8. There is Mercury, Venus Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Now, There is also Pluto, which was recently classified as a Dwarf Planet, a Plutoid, to be exact, and it is still in our Solar System. To add, there are also other Dwarf Planets in our Solar System, and currently, there are 4 of them that are officially recognized. They are Pluto, Eres, Ceres, and Makemake.

Without Pluto.. there are 8 planets... How sad.. at 32 years old finding out that Pluto is no longer considered a planet! For about 70 years it was considered a planet.. how truely sad is that!!!

In August 2006, the International Astronomical Union (IAU) re-defined the word planet, meaning that the planets in the Solar System are eight. Pluto became considered a dwarf planet.

Murcury, venus, earth, mars, jupiter, saturn, uranus, neptune... Pluto has been declassified as asteroid.

"Under IAU definitions, there are eight planets in the Solar System. In order from the Sun, they are the four terrestrials, Mercury, Venus, Earth, and Mars, then the four gas giants, Jupiter, Saturn, Uranus, and Neptune. The Solar System also contains at least five dwarf planets: Ceres, Pluto (originally classified as the Solar System's ninth planet), Makemake, Haumea and Eris. With the exception of Mercury, Venus, Ceres and Makemake, all of these are orbited by one or more natural satellites. As of March 2009, there are 344 known extrasolar planets, ranging from the size of gas giants to that of terrestrial planets."
