Tárgy: Pluto torpe bolygo a tovabbiakban
Üdv!
Lefokozták a Plútót, a továbbiakban törpebolygó a Ceres és a könnyen
megjegyezhető nevű 2003 UB313-mal egyetemben. Lehet átírni minden 1930 óta
megjelent kiadványt, a naprendszernek 8 bolyógója lett.
Íme a hír a http://spaceweather.com -ról:
Today, astronomers at the International Astronomical Union's General
Assembly in Prague decided that the Solar System has eight planets, and
Pluto is not one of them. Pluto has been declared a "dwarf planet." Joining
Pluto in the dwarf planet category are giant asteroid Ceres and Pluto's
cousin 2003 UB313.
To be a planet, the assembly ruled, a world must meet three criteria:
(1) It must have enough mass and gravity to gather itself into a ball.
(2) It must orbit the sun.
(3) It must reign supreme in its own orbit, having "cleared the
neighborhood" of other competing bodies.
