how many planets are their in our solar system, ive heard we found a few new ones?

Answer 1

I also heard about the 10th one long back by some name starting with "K" but the news lost in the oblivion & most probably the planet.

Answer 2

The solar system consists of the Sun; the nine planets, more than 130 satellites of the planets, a large number of small bodies (the comets and asteroids), and the interplanetary medium. (There are probably also many more planetary satellites that have not yet been discovered.) The inner solar system contains the Sun, Mercury, Venus, Earth and Mars: The planets of the outer solar system are Jupiter, Saturn, Uranus, Neptune and Pluto: but....on May 22, 1998, a newly-discovered planetoid (minor planet) formerly known as Planet. 13241 is now named “Planet Biyo” after a Filipino teacher.

This minor planet Biyo, has a diameter of four to nine kilometers, a small red planet rotating around the sun and located between Mars and Jupiter, formerly called planet 13241, was named by the Massachusetts Institute of Technology (MIT) Lincoln Laboratory,United States in the honor of Dr. Josette Biyo, a teacher at the Philippine Science High School in Iloilo City, Philippines who won the International Excellence in Teaching Award during the Intel International Science and Engineering Fair (Intel ISEF) held in Louisville, Kentucky in 2002.

Other minor planets yet to be discovered is not been officially acknowledged and named by the world authorities, hence: these new information can be finely be considered the new one, making Biyo a new planet, therefore our solar system has now a total of 10 planets.

Answer 3

Currently, there are nine well-known planets in our Solar system. But no longer is Pluto a lonely outpost at the edge of an unknown frontier. Continued discoveries reveal that astronomers are only on the verge of discovering vast new worlds beyond - in the Kuiper Belt and possibly the Oort Cloud. At the same time, new moons are also being discovered, both around existing planets and within these mysterious new worlds. Once the existence of a moon is confirmed and its orbit determined, the moon is given a final name by the International Astronomical Union (IAU), the organization that assumed this task since 1919.

Answer 4

Currently there are nine planets in our solar system.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.

No, they have not found a new planet in our solar system. What was discovered was another object in the growing list of objects called "Kuiper Belt Objects" or KBOs.

The Kuiper Belt is a disk-shaped region out past the orbit of Neptune, roughly 30 to 100 AU from the Sun. It contains many small (and some large) icy and rocky bodies. From time to time, a KBO will have its orbit disturbed in some way so that its orbit changes to cross inside that of Neptune.

It is estimated that at least 35,000 KBOs are larger than 100 km in diameter. Several larger KBOs have also been discovered.

Pluto's existance as a planet is controversy. Considering that other recently discovered Kuiper Belt objects e.g. Quaoar and Sedna that are almost as large as Pluto. The existance of Pluto as a planet would probably means that there are 100s of planets out there including Xeno, Quaoar and Sedna. Which make planets no longer unique and rare.

By removing the existance of Pluto as a Planet, we will be scaled down to 8 planets in our solar system. But well so far, the International Astronomical Union still classifies Pluto as a planet.

And as long as there isn't any amendment from International Astronomical Union, we only recognise 9 planet in our solar system.

Additional information: To classify as a planet, the mass have to fulfill these conditions:
1) Orbit around our Sun, the stars or stellar remnants (like pulsars)
2) Rotate on itself at different rates
3) Should have a mass greater than the total mass of all other bodies in nearby orbits (Currently there isn't any fixed mass for us to refer to, thus causing alot of debates.)

Answer 5

it depends what you define a planet to be. Pluto is really just a big ice ball. Mercury, Venus, Earth and Mars are all rocky planets, then Jupiter, Saturn, Uranus and Neptune are all gas giants. This has to do with their distance from the sun. Then all of a sudden you've got a big ball of ice, Pluto. So its not really concidered a planet. If you do concider it a planet, then there could be lot's more planets in the oort cloud.

Answer 6

Hi,

They say 10 planets. But the latest discovered is not yet certainly known to be a planet.

It is shiny they say, but don't really know it is a planet yet.

Answer 7

i read that they found two new ones actually bigger than pluto. so depending on their definitions, then we should have 11. and these scientists argue that if they don't consider these two new ones, then pluto shouldn't be considered too. so there should be only 8.

also, a Filipino teacher recently discovered a planet that was named after her, Biyo.

Answer 8

I believe there to be 16 in all, so a few more to be discovered and I' sure I won't be around to see if I was right about it either, lol

Answer 9

Still only 9 planets.There not sure if their asteroids or planets

Answer 10

I think the count is up to 15 or so. Just click below to find out.
