Xena.jpgXena: another "Tenth Planet"? (2003 UB313)57 visiteNASA's Hubble Space Telescope has resolved the Tenth Planet, now nicknamed Xena, for the first time and has found that it is only just a little larger than Pluto.
Though previous ground-based observations suggested that Xena was about 30% greater in diameter than Pluto, Hubble observations taken on Dec. 9 and 10, 2005, yield a diameter of 1.490 miles (with an uncertainty of 60 miles) for Xena. Pluto's diameter, as measured by Hubble, is 1.422 miles. Xena is the large object at the bottom of this artist's concept. A portion of its surface is lit by the Sun, located in the upper left corner of the image. Xena's companion, Gabrielle, is located just above and to the left of Xena.06/14/21 at 15:55MareKromium: Bene Max. Ti ringrazio. Io non sono un tecnico di ...

Comet_Borisov_-_GIF_3.gifFrom far away: the Comet Borisov through the Solar System (GIF-Movie)286 visiteGuardate bene! EccoVi la differenza (REALE ed IN FATTO) tra un Fly-By and uno Swing-By...E senza dimenticare "Oumuamua"!
As the first known object of its type, Oumuamua presented a unique case for the International Astronomical Union (IAU, for short), which assigns designations for astronomical objects. Originally classified as comet C/2017 U1, it was later reclassified as Asteroid A/2017 U1, due to the absence of a coma (--> "Chioma", in Italian).
Once it was unambiguously identified as coming from outside the Solar System, a new designation was created.
The name comes from the Hawaiian word "oumuamua", meaning 'scout' (from ou, meaning 'reach out for', and mua, reduplicated for emphasis, meaning 'first, in advance of', and reflects the way this object is like a scout or messenger sent from the distant past to reach out to Humanity.
It roughly translates to 'first distant messenger' (or "The First Messenger from the distance").
Before the official name was decided upon, the name "Rama" was suggested by the name given to an Alien Spacecraft discovered under similar circumstances in the 1973 science fiction novel "Rendezvous with Rama", by Sir Arthur C. Clarke.MareKromium01/29/21 at 09:27Anakin: In effetti ? molto acuto. Ha fatto quasi un'in...
