How many planet's r there in da whole solar system????

Answer 1

Hi Cool,

With scientists changing the requirements
to be a planet, I do not know anymore.
I for one, disagree with their disqualification
of Pluto due to its unruly and elliptical orbit -
I mean really,..
These guys are so behind in what they should
be accomplishing that they are finding ways
to excuse their profession....
or something like that...

Answer 2

......and then there were 8.

PRAGUE, Czech Republic - Pluto, beloved by some as a cosmic underdog but scorned by astronomers who considered it too dinky and distant, was unceremoniously stripped of its status as a planet Thursday.

The International Astronomical Union, dramatically reversing course just a week after floating the idea of reaffirming Pluto's planethood and adding three new planets to Earth's neighborhood, downgraded the ninth rock from the sun in historic new galactic guidelines.

Pluto, a planet since 1930, got the boot because it didn't meet the new rules, which say a planet not only must orbit the sun and be large enough to assume a nearly round shape, but must "clear the neighborhood around its orbit." That disqualifies Pluto, whose oblong orbit overlaps Neptune's, downsizing the solar system to eight planets from the traditional nine.

The decision by the IAU, the official arbiter of heavenly objects, restricts membership in the elite cosmic club to the eight classical planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

Pluto and objects like it will be known as "dwarf planets".

Under the new rules, two of the three objects that came tantalizingly close to planethood will join Pluto as dwarfs: the asteroid Ceres, which was a planet in the 1800s before it got demoted, and 2003 UB313, an icy object slightly larger than Pluto whose discoverer, Michael Brown of the California Institute of Technology, has nicknamed "Xena." The third object, Pluto's largest moon, Charon, isn't in line for any special designation.

Answer 3

What you ask is about the whole solar system. The solar system is defined as our sun and nine, er... 8 planets and a dwarf planet named Pluto. That is the solar system, or at least our solar system.

Our solar system is in the Milky Way Galaxy, which contains many solar systems, each containing many planets. The center of each of these solar systems is most likely a sun similar (larger or smaller) to ours, which contributes to the stars you see in the sky. When you keep looking up, you are seeing someone else's sun.

Answer 4

There are now 8 major planets and 4 dwarf planets. The 8 major planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The new Dwarf Planets are Pluto/Charon (double dwarf planet), Ceres, and 2003 UB313. The International Astronomical Union voted on August 24, 2006 to accept this new definition. Cheers!

Answer 5

8

Answer 6

9

Answer 7

8.

Pluto isn't regarded as a planet because of its very small size that is smaller than our moon, a very irregular orbit, and chunks and evidence of ice and dust, made it believed to rather be a comet.

Saw it on the net, tv, and latest mags and books. I can't believe it though, because i hoped there was 10 planets in the solar system.

Answer 8

Apparently only 8, as opposed to the usual 9. This week, I believe it was, science wants to discredit Pluto as a planet because:
1) It is smaller than the moon
2) Has an irregular orbit
3) They think it is simply only a comet.

Answer 9

8....The definition of planet has been recently revised so that pluto can not be called a planet. Prior to the revision there were 12 known planets 2 of which were actually moons that are larger than Pluto.

Answer 10

Scientists now changed it to 8. Pluto is no longer a planet.
