  The fourth microlensing planet, otherwise known as OGLE-2005-BLG-169Lb, was
discovered by a collaboration of US, NZ, Polish and UK astronomers in
2005-2006. Recently the results were confirmed by the Hubble Space Telescope
and by the Keck Observatory. OGLE-2005-BLG-169Lb is the first microlensing
planet to receive such confirmation. Its discovery and confirmation are
described here in an historical context.
