What Defines a Planet?

 

What constitutes a planet? The International Astronomical Union (IAU) developed some definitions in 2001, modified them again in 2003, and as of August 24, 2006, the IAU has come up with another definition. The IAU said in a statement that the definition for a planet is now officially known as "a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape and © has cleared the neighborhood around its orbit."

 

A "dwarf planet" is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, © has not cleared the neighborhood around its orbit, and (d) is not a satellite.

 

All other objects except satellites orbiting the Sun shall be referred to collectively as "Small Solar-System Bodies". According to the IAU, more dwarf planets are expected to be announced in the coming months and years. Currently, a dozen candidate dwarf planets are listed on IAU's dwarf planet watchlist, which keeps changing as new objects are found and the physics of the existing candidates becomes better-known."

de fapt,mai exista un cerc de planete(Kuiper) in care se afla Eris,Xena,Makemake si alte planete apoi cometa Halley,apoi norul lui Oort...si centura de asteroizi ar fi considerata planeta,deoarece in acel loc,planeta phaeton a explodat uitati:

Copilul Alexandru Pargaru spune ca el vine de pe planeta Wertex situata intre Luna si Soare. :P: A cata planeta este planeta Wertex???!!!!???? :stars: (w00t)

Mai trage-ti cateva palme, ... NU EXISTA "intre Luna si Soare" caci Luna isi schimba mereu pozitia in jurul Pamantului, asa ca reperul poate fi Pamantul, dar nu Luna.

 

Corect: planeta X situata intre Pamant si Soare, restul sunt prostioare de-ale pruncilor. :bye:

dar parca Sedna ii ramasese nu Xena... :cry:

Am vazut la TV o stire despre un telescop nou construit in Spania care este mai puternic ca Hubble. :cry:

Pana in prezent sunt 14 planete noi descoperite in sistemul solar, de clasa plutino: Xena, Sedna, Quaoar, Varuna, ...

[K0ntr0VerSy 630]

14 planete noi sau 14 planete cu totul?

 

Te pomenesti ca a aparut o noua planeta: Terra!

nu e cumva Eris? http://en.wikipedia.org/wiki/Eris_(dwarf_planet)
