How should S/2011 (134340) 1
be called?

Any suggestions?

How about KALI ?

It's not Greek, but ...

>>NASA'S HUBBLE DISCOVERS ANOTHER MOON AROUND PLUTO
>>
>>WASHINGTON -- Astronomers using the Hubble Space Telescope discovered
>>a fourth moon orbiting the icy dwarf planet Pluto. The tiny, new
>>satellite, temporarily designated P4, was uncovered in a Hubble
>>survey searching for rings around the dwarf planet.
>>
>>The new moon is the smallest discovered around Pluto. It has an
>>estimated diameter of 8 to 21 miles (13 to 34 km). By comparison,
>>Charon, Pluto's largest moon, is 648 miles (1,043 km) across, and the
>>other moons, Nix and Hydra, are in the range of 20 to 70 miles in
>>diameter (32 to 113 km).
>>
>>"I find it remarkable that Hubble's cameras enabled us to see such a
>>tiny object so clearly from a distance of more than 3 billion miles
>>(5 billion km)," said Mark Showalter of the SETI Institute in
>>Mountain View, Calif., who led this observing program with Hubble.
>>
>>The finding is a result of ongoing work to support NASA's New Horizons
>>mission, scheduled to fly through the Pluto system in 2015. The
>>mission is designed to provide new insights about worlds at the edge
>>of our solar system. Hubble's mapping of Pluto's surface and
>>discovery of its satellites have been invaluable to planning for New
>>Horizons' close encounter.
>>
>>"This is a fantastic discovery," said New Horizons' principal
>>investigator Alan Stern of the Southwest Research Institute in
>>Boulder, Colo. "Now that we know there's another moon in the Pluto
>>system, we can plan close-up observations of it during our flyby."
>>
>>The new moon is located between the orbits of Nix and Hydra, which
>>Hubble discovered in 2005. Charon was discovered in 1978 at the U.S.
>>Naval Observatory and first resolved using Hubble in 1990 as a
>>separate body from Pluto.
>>
>>The dwarf planet's entire moon system is believed to have formed by a
>>collision between Pluto and another planet-sized body early in the
>>history of the solar system. The smashup flung material that
>>coalesced into the family of satellites observed around Pluto.
>>
>>Lunar rocks returned to Earth from the Apollo missions led to the
>>theory that our moon was the result of a similar collision between
>>Earth and a Mars-sized body 4.4 billion years ago. Scientists believe
>>material blasted off Pluto's moons by micrometeoroid impacts may form
>>rings around the dwarf planet, but the Hubble photographs have not
>>detected any so far.
>>
>>"This surprising observation is a powerful reminder of Hubble's
>>ability as a general purpose astronomical observatory to make
>>astounding, unintended discoveries," said Jon Morse, astrophysics
>>division director at NASA Headquarters in Washington.
>>
>>P4 was first seen in a photo taken with Hubble's Wide Field Camera 3
>>on June 28. It was confirmed in subsequent Hubble pictures taken on
>>July 3 and July 18. The moon was not seen in earlier Hubble images
>>because the exposure times were shorter. There is a chance it
>>appeared as a very faint smudge in 2006 images, but was overlooked
>>because it was obscured.
>>
>>Hubble is a project of international cooperation between NASA and the
>>European Space Agency. NASA's Goddard Space Flight Center in
>>Greenbelt, Md., manages the telescope. The Space Telescope Science
>>Institute (STScI) in Baltimore conducts Hubble science operations.
>>STScI is operated for NASA by the Association of Universities for
>>Research in Astronomy Inc. in Washington.
