moon
2003 by astronomers KS Noll and DC Stephens was the discovery of a moon announced the Borasisi km orbits at a distance of only 4660 ± 170th The discovery was made using the infrared - spectrometer of the Hubble Space Telescope . The diameter of the companion is estimated to be around 137 km, which is why Borasisi can be classified as a double asteroid with its almost equally large companion. The moon was given the name Pabu (full name: (66652) I Pabu ) to match the naming of the main body . Pabu as the name for moon also comes from the fictional religion of " Bokononismus ".
