| Ultimi commenti - Pluto and Charon: The "Double Planet" |
PLUTO.jpgPluto in "true color"225 visiteOvviamente non sappiamo molto di Plutone, ma le più recenti scoperte parlano di vasti depositi di acqua ghiacciata sulla sua superficie. Sappiamo pure che Plutone possiede un'atmosfera (composta da azoto, metano ed altri gas in misura minore) oltremodo sottile la quale, inevitabilmente, "ghiaccia" all'afelio del Pianeta (afelio--->il punto più lontano dal Sole).
Il lancio della Sonda New Horizons è stato concepito secondo tempistiche le quali dovrebbero portarla a ridosso di Plutone prima che la sua atmosfera ghiacci totalmente e quindi permetterci di studiarla (un minimo) ed analizzarne le componenti.
Facts-bites about Pluto&Charon:
Pluto orbits the Sun once every 248 years.
A person on Pluto would weigh 1/15 what they weigh on Earth - for comparison, the astronauts on the Moon had 1/6 of their Earth weight.
Pluto is named after the Greek god of the underworld.
The symbol for Pluto ("PL") is tribute to Percival Lowell, who started the search for the ninth planet in the early 1900s.
Charon is 20 times closer to Pluto than our moon is to Earth.
Pluto was discovered in 1930 by American astronomer Clyde Tombaugh.
American astronomers James Christy and Robert Harrington discovered Charon in 1978.
Charon is named after the mythological boatman who ferried souls across the river Styx to Pluto for judgment.
At 1,470 miles (about 2,370 kilometers) across, Pluto could fit between Washington, D.C. and Denver, Colorado.
Charon is half of Pluto's diameter - making it the largest satellite relative to the planet it orbits.
Pluto is an ice dwarf - a "new" type of planet common to the deep outer solar system.
Pluto-Charon is the solar system's only known binary planet.
Pluto's surface is among the most contrasty in the solar system.
Pluto has weather, winds, hazes, chemistry and an ionosphere.
Pluto's estimated surface temperature falls between --378 to --396 degrees F (-228 to -238 C).
Pluto is one of only two planets that rotates on its side - Uranus is the other.
Pluto's surface has nitrogen, methane and carbon monoxide ices on it.
A radio signal moving at the speed of light takes about 4 hours to reach Pluto from Earth.
The Kuiper Belt is a collection of icy, rocky objects residing beyond Neptune's orbit.
The first Kuiper Belt Object was discovered in 1992.
Some Kuiper Belt Objects (like Pluto) have an average reddish color, while others are gray.

A - Pluto and Charon - HST.jpgPluto and Charon from the Hubble Space Telescope135 visiteAggiornamento del 19 Agosto 2006: il Sistema "Plutone-Caronte", sino a ieri considerato un sistema equiparabile a quello Terra-Luna (in cui Plutone, al pari della Terra, è il Corpo Maggiore e Caronte, invece ed al pari della Luna, quello minore e dunque SOLO Satellite del primo), in accordo ad una decisione dell'International Astronomical Union (IAO) è stato ora rubricato come "Doppio Pianeta".
Caption IAU originale:"Both Pluto and Charon each are large enough (massive enough) to be spherical. Both bodies independently satisfy the definition of “planet”. The reason they are called a “double planet” is that their common centre of gravity is a point that is located in free space outside the surface of Pluto. Because both conditions are met: each body is “planet-like” and each body orbits around a point in free space that is not inside one of them, the system qualifies to be called a “Double Planet”.
