SATELLITES OF JUPITER AND SATURN
Further to IAUC 8502 and 8730, the IAU Working Group for
Planetary System Nomenclature (WGPSN) has approved the following
new designations and names of satellites of Jupiter and Saturn:
Jupiter XLIX Kore = S/2003 J 14
Saturn XXXVI Aegir = S/2004 S 10
Saturn XXXVII Bebhionn = S/2004 S 11
Saturn XXXVIII Bergelmir = S/2004 S 15
Saturn XXXIX Bestla = S/2004 S 18
Saturn XL Farbauti = S/2004 S 9
Saturn XLI Fenrir = S/2004 S 16
Saturn XLII Fornjot = S/2004 S 8
Saturn XLIII Hati = S/2004 S 14
Saturn XLIV Hyrokkin = S/2004 S 19
Saturn XLV Kari = S/2006 S 2
Saturn XLVI Loge = S/2006 S 5
Saturn XLVII Skoll = S/2006 S 8
Saturn XLVIII Surtur = S/2006 S 7
RING OF URANUS
The IAU WGPSN has recently designated the Uranian ring 1986 U
2R (cf. IAUC 8373; Stone and Miner 1986, Science 233, 39) the "zeta
ring".

JPL/CIT; M. C. Nolan and A. A. Hine, Arecibo Observatory; G. J.
Black, University of Virginia; and L. M. Carter, Smithsonian
Institution, report that Goldstone (8560 MHz, 3.5 cm) and Arecibo
(2380 MHz, 12.6 cm) radar observations during Mar. 27-Apr. 3 reveal
that the minor planet 2006 VV_2 (cf. MPEC 2006-V47, 2006-W87),
which passed only 0.0226 AU from the earth around Mar. 31.25 UT
(with computed V = 10.0) and has H = 16.7 (MPO 118180), is a binary
system. Preliminary estimates for the component diameters are 1.8
and > 0.3 km. The maximum orbital distance between the components
is at least 1.5 km.
