How many planets r there in the solar system including the recently discovered ones?
Question:
Answer:
The new things they discovered are Sedna and Quaoar. So there could be 11 planets
The planet Quaoar is the 11th planet in the meridian solar system . Its orbit is different than the other planets in our solar system. The surface of Quaoar is barren it consists mainly of hard rock and ice there is a light atmosphere around the planet Quaoar but it's not fit for humans. There are no life forms on the surface of Quaoar it is a dead planet and you could say the planet Quaoar is a large rock trapped in the darkness of the Kuiper belt in a orbit around our sun.
The planet Sedna is the second most reddish planetary body in the Solar System, after Mars. Although inclined by only around 11.9 degrees from the ecliptic where the eight major planets orbit, Sedna's distant orbit is extremely elliptical indicating that its formation and orbit may have been influenced by by a passing nearby star during the early years of the Solar System, when Sol formed out of a molecular cloud with many other closeby stars around 4.6 billion years ago. There is indirect evidence (an unexpectedly slow 40-day rotation) that Sedna has its own moon, which astronomers hope to confirm with the Hubble Space Telescope (more information and images from NASA. The icy object will move closer to the Sun over the next 72 years -- to 76 AUs of Sol -- before receding back towards the inner Oort Cloud.
This is about their discoveries: http://science.nasa.gov/headlines/y2005/...

there are about nine exactly and an additionalone called planet x
There 9 planets in the solar system
Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
Neptune
Pluto
+ one more without an official name yet
The most recently discovered planet is Pluto.
This brings the total to 9:
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto
All other bodies that orbit the sun are either in unpredictable orbits or have not yet been proven to be in an orbit around the sun. As such there are no officially recognised planets other than those i mentioned above.
Planet 'x' is arguable as to whether it is a planet, which is why it has not been listed as one.
Astronomers have detected what could be the Solar System's 10th planet.
It was first seen by astronomers using California's Palomar Observatory, and has been given the name "Sedna" after the Inuit goddess of the ocean.
Observations show it measures about 1,180-2,360km (730-1,470 miles) across, making it similar in size to Pluto.
There are now officially ten:
Mercury, Venus, Earth, Mars, Saturn, Jupiter, Neptune, Uranus, Pluto and Sedna
There are nine OFFICIALLY nine designated planets in our solar system. The recently discovered planet-like object beyond Pluto may become the tenth.
God should be spelled B-I-G B-A-N-G

The last time I heard an official report it was 10, but its been a while...
The International Astronomical Union recognizes 9 celestial objects as planets in our solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. However, others disagree on the planet count - there are those who say Pluto is not a planet, there are those who argue if Pluto is a planet then Xena (Ub313, discovered recently; bigger than Pluto and has a moon.) logically must also be a planet.Since there is no elucidated definition for a planet, anyone can be right.
