The (sometime Manchester) Guardian newspaper for 26th Aug 2006, on page 32 of its G2 section, reports that (sic) "A rock needs to have a mass of about 5,1020kg for gravity to give it a nice round planet-y sort of shape ..." Even for a newspaper with a noble tradition of embarrassing misprints, an error of 16 (presumed) orders of magnitude must surely be close to a record! WFL
