How many planets are there in our solar system and please name all them?

This is all hot off the press and there are conflicting reports.

As of earlier today, we are down to eight: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Pluto got stripped of planetary status or so Yahoo News said.

The report went on to say that 1 Ceres, Xena (same things as UB-313) Charon and Pluto are to be known as dwarf planets (not minor planets and not Plutons)

JIbba Jabba's comments are interesting news. 2 Pallas 4 Vesta and 10 Hygiean, like 1 Ceres, are all in the asteroid belt (between Mars and Jupiter) not the Kuiper Belt (beyond Neptune) so the new category they are to be fitted into covers both belts it would seem and they are not all Trans-Neptunian Objects as Jibba-Jabba asserts.

A definition that specified that onjects had to be spherical would exclude Hygiea which is oblong Hygiea (discovered 1849) is the fourth largest asteroid, with diameters of 350–500 km and a mass estimated to be 3% of the total mass of the asteroid belt.

1 Ceres (discovered 1801), 2 Pallas (discovered 1802), 3 Juno (discovered 1804) and 4 Vesta (discovered 1807) were all regarded as planets when discovered, Partly because the concept of asteroid was only introduced by Sir William Herschel in 1802 after Pallas was discovered (he was disappointed how small Ceres and Pallas were) and there was no alternative category to give them.

Once more asteroids began to be discovered (starting with 5 Astraea in 1845 and rapidly reaching over 100 by 1868) then they were demoted from planetary status, This was the outcome the last time the IAU had a classification tussle on their hands.

Our solar system officially 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 discovery of an object larger than Pluto in 2005 rekindled the debate over whether such objects, belonging to the "Kuiper Belt" -- a collection of icy bodies located beyond Neptune-- should be called planets. Pluto itself belongs to the Kuiper Belt.

Mercury, Venus, Earth, Mars, Saturn Jupiter, Uranus and Neptune,and 3 dwarf planets called Ceres, Pluto, and UB313 and nine trans-Neptunian objects: Hygiea, Vesta, Pallas, Orcus, Ixion, Varuna, 2002 TX300, 2003 EL61, Quaoar, 2005 FY9, 2002 AW197 & Sedna.

As of today, there are eight: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Pluto, Xena and a few others are now dwarf planets, not full-status planets.

I learned in school 9, but I'm sure that's not correct. According to my learning it goes Mars, Venus, Earth, Mercury, Jupiter, Saturn, Uranus, Neptune, Pillows "My Very Eccentric Mother Just Sold Us Nine Pizzas".

Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Charon and 2003 UB313 (provisional name). And by the way, VERY GOOD question. It gets one's mind to thinking....Bravo

Pluto was stripped of its 'planet' status today.

It is now classified a 'dwarf planet' as is Charon, Ceres, and UB313 (Xena)

There are now eight official 'planets'.

Eight planets....Pluto was decategorized today by astronomers.

mercury, venus, earth, mars, jupiter, neptuen, saturn, and uranus.

Every planet that we have learned excluding Pluto, of course. ;)

You're annoying. I know I won't get a best answer for this, but yeah who cares? I just wanted to get that off my chest...
