Though the figures are tough to keep up with - they are changing, almost daily - the Kepler Space Telescope (KST) has discovered, to date, over 4,500 exoplanet candidates, ~3,400+ of which have been confirmed.

QX Pup

Update (July 7, 2015):  I-band coverage of QX Pup by AAVSO observers since 2010 clearly shows that the period given in the 4th Edition of the GCVS of 648: days is incorrect. A phase plot by Sebastián Otero of these data shows that the period of QX Pup in Ic is 551 days.
