UB-313.jpgUB 313: is this the "10th Planet"?85 visiteWhat do you call an outer Solar System object that is larger than Pluto? Nobody is yet sure, but the question arose recently when 2003 UB313, an object currently twice as far out as Pluto and not in the plane with the rest of the Planets, was verified recently to be 30% wider than Pluto. UB313's size was estimated (of course in a VERY approximate way!) by measuring how much infrared light this celestial body emits. Previous size estimates were based only on visible light and greatly affected by how reflective the object is.
Whether 2003 UB313 is officially declared a planet will be answered shortly by the International Astronomical Union (IAU).
In the above picture, a scientific artist has imagined UB313 in its distant orbit around the Sun, coupled with a hypothetical moon.

The_Rings-PIA10081.jpgIcy Rings78 visiteCaption NASA:"This is an artist concept of a close-up view of Saturn's Ring particles. The planet Saturn is seen in the background (yellow and brown).
The particles (blue) are composed mostly of ice, but are not uniform. They clump together to form elongated, curved aggregates, continually forming and dispersing. The space between the clumps is mostly empty. The largest individual particles shown are a few meters (yards) across". MareKromium

The_Rings-PIA10082.jpgMittens78 visiteCaption NASA:"This is an artist concept of the view from Cassini during the star occultation that detected "Mittens," the small object to the right of the star. As Cassini watched the star pass behind Saturn's F-Ring (foreground), the star blinked out when Mittens blocked it, indicating it may be a solid moonlet".MareKromium
