Is a retrograde orbit satellite irregular inner belonging to the group of satellites and which are closest to earth. 4,276,000 kms orbits in 266.56 days, is inclined 145 to the ecliptic and has an orbital eccentricity of 0.1459. As for physical characteristics, it is a body of only 11 kms in diameter, an average density of 1.3 g/cm3 and an albedo of only 0.04. It is estimated that the surface temperature is 65K (-208 C).
"S/2001 U 3 - MPEC 2003-T29 has astrometry and orbital elements (a = 0.029AU, e = 0.14, i = 147 deg, P = 267 days, H = 12.8) by BG Marsden for a new Uranian satellite Observed on 2001 Aug. 13, 25, and September. 21 by M. Holman, B. Gladman, and Collaborators (see IAUC 7980). Gladman Identified Further observations zip auction in 8.2-m Very Large Telescope UT3 images taken by P. Rousselot and O.
