"Dwarf Planets:

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."

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:

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

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

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

14 planete noi sau 14 planete cu totul?

Te pomenesti ca a aparut o noua planeta: Terra!
