[11] According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Claudiomaccone measures 3.203 kilometers in diameter and its surface has a high albedo of 0.432,[6][7] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony S-type asteroids of 0.20 and calculates a diameter of 4.30 kilometers with an absolute magnitude of 14.2.
[9] After the binary nature of Claudiomaccone was announced (see below), follow-up observations by a group of French, Swiss and Italian astronomers (including Claudio Maccone) in 2008 and 2012, gave a period 3.1873 and 3.18701 hours with an amplitude of 0.16 and 0.12 magnitude, respectively (U=2/2+).
[9] The discovery was announced in December 2005[4] Based on a secondary to primary mean-diameter ratio of larger than 0.31, the moon's diameter is estimated to be at least 1.24 kilometers.
Outside the Solar System, at a distance of 550 AU, FOCAL could have a significantly better sensitivity detecting radio signals due to the Sun's magnifying gravitational lensing effect, as predicted by general relativity.
