New Planet-Shaped Body Found in Our Solar System

Astronomers announced today the discovery of the largest object in the solar system since Pluto was named the ninth planet in 1930. The object is half the size of Pluto, composed primarily of rock and ice, and circles the sun once every 288 years.
Named Quaoar (pronounced KWAH-o-ar), the object resides in the Kuiper belt, a region of the sky beyond the orbit of Pluto and about 4 billion miles (6.5 billion kilometers) from Earth. The Kuiper belt is chock full of remnants from the planet-formation era of the solar system.

Although there are no NEW discoveries in the Solar System lately but there is a proposed change which can occur in the way planets are classified in it.The new Solar System will have 8 planets i.e Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.Plus there will be four Plutons (Yeah you heard it right!!!).Plutons in simple terms mean a B-League of planets.Pluto will now be a pluton.The other three plutons being The asteroid Ceres and Pluto's moon Charon and an object known as 2003 UB313 or Xena.By the way i am not behind all this, the people who want to distroy our good old Solar System are International Astronomical Union (IAU)....

Jupiter has been referred to as a mini Solar System because of the thousands of small bodies it directly controls through its gravity. Choose a link below to find out more about these minor bodies near and around Jupiter.

Irregular satellites

Regular satellites

Trojans

Jupiter family comets

Since Jupiter is the largest planet in our Solar System it has influenced our neighborhood second only to the Sun.
The other giant planets Saturn, Uranus, and Neptune also have regular and irregular satellites. Neptune also has Trojan asteroids. Click on the planet link under its current satellite count to learn more about each of the satellite systems.

with the revised definition of a planet, our solar system apparently now has 12 planets.

mercury venus earth mars ceres jupiter saturn uranus neptune pluto charon xena.

this is a very controversial 'upgrade' and many are still on different sides of the fence regarding this issue. if this definition sticks though, we may have more planets coming our way.

If you are talking about those supposed planets they are not new discoveries. Astronomers knew about them. They are trying to classify them as planets. If approved we will have 12 planets. Ceres (in the asteroid belt), Charon (Pluto's moon), Xena .

REALIGNMENT OF THE PLANETS
Arts and science: Notion of new planets proves a shock to our (solar) system

By Julia Keller
Tribune cultural critic
Published August 23, 2006

In a WBEZ-FM interview earlier this year, the luminous Laurie Anderson confirmed that during her childhood in Glen Ellyn, she'd often lie on her back and gaze at the sky.

She still does that, no matter where she is. Why?

Simple, the artist said: "Continuity."

The sky can seem like that. Like your oldest and most reliable friend. Like the stable point amid life's tumult. Like the only real grown-up in the room. Earnest. Settled.

Yet here we are, a day away from having many of our calm certitudes about the sky and its most dependable contents -- planets -- rudely upended. On Thursday, the International Astronomical Union will decide whether to change the definition of a planet, a referendum of some 2,500 scientists meeting in Prague that has captured the world's attention because it could add a bunch of new planets to our solar system or oust Pluto. And, frankly, because it seems to reveal just how arbitrary and up-for-grabs are the scientific "truths" by which we fix our personal compasses.

What's next? A vote of no-confidence for gravity? The repeal of the Second Law of thermodynamics?

Things won't be the same for compulsive sky-gazers -- and that means everybody -- ever again. It's disconcerting to find out that with the change of a definitional word here and there, with the shift of a semicolon or some computational sleight of hand, the entire universe suddenly is reconfigured. Nine planets in the solar system? Nah. Let's say -- oh, heck, what sounds good this week? OK, let's say 14!

So much for continuity.

Kim Stanley Robinson, though, the author of the widely admired science fiction trilogy "Red Mars," "Green Mars," "Blue Mars," pooh-poohed the anxieties. He said we've got this universe-plunged-into-chaos thing all wrong.

Reached by e-mail at his California home, and asked to share his ruminations on the upcoming vote, Robinson advised us, in effect, to take the lens caps off our telescopes.

The proposed change in planetary designation "reveals in a small way how science works -- that it continually re-examines its categories in light of the new data it receives and doesn't get caught proclaiming an old situation is `true' when new information changes things, as opposed to, say, religions or political ideologies," he wrote.

"Despite a certain fondness for what one learned in one's youth," Robinson continued, "for facts and systems of all kinds, among which objects like `planets' might have seemed among the most permanent, when new information forces a change in how we think of our categories, people who believe in using science to interpret the world are more interested in having accurate descriptions than in having their nostalgias upheld.

"It's pretty cool, all in all, to see this as an example of science in action . . . and also to think there are more things out there to imagine," he added.

Robinson's novels, it may not surprise you to discover, put the "science" back into "science fiction," grounded as they are in the known biological, physical and geological realities of Mars. No tentacle-waving, mind-reading, minty-green Martians populate his trilogy. Instead, a bracing air of plausibility blows through the books, which is doubtless why many scientists name Robinson's trilogy as the only science fiction they deign to read.

Thus when it comes to a contemplation of efforts to rejigger our notion of naming objects in the sky, Robinson is an ideal resource. He's a one-man amalgam of the arts and sciences.

"One is reminded again how huge and precise the vision of the universe is that science has given us, always getting widened and sharpened both," he wrote. "It's always something agreed upon by way of a shared explication of evidence that everyone has -- so that no one has to take it on faith, but can examine the arguments and evidence point by point, and presumably will come to an agreement because nothing otherworldly has been asserted at any point." Nary a brain-eating, bazillion-eyed alien in sight, in other words.

We crave continuity and certainty but in the end, the only constant on earth or sky is change. And the only truth-in-advertising banner that the universe can offer is this one, unfurled across its unfathomable length and breadth with an "Eat at Joe's!" earnestness: "Watch This Space."
