If it has to be Greek, how about

ACHLYS

the personification of Eternal Night, a daughter of NYX ?

>>>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.
