The Age of Miniaturization:Smaller is Better
OGLE-2005-BLG-390Lb is believed to be the smallest exoplanet. For now.
Extrasolar Planet = Exoplanet = Planet orbiting a star other than the Sun.
As of April 18th 2006: 188 planets are confirmed (and not retracted yet) according to the Paris Observatory Extrasolar Planets Encyclopedia
Of these 188, the spread of detection is as follows:
Radial Velocity – 176Microlensing – 4Imaging – 4Pulsars – 4
Main Detection Methods:
1. Radial Velocity (doppler shift)2. Astrometry (uses proper motion, extremely limited)3. Gravitational Microlensing (planet and parent star pass in front of background star)4.Transit Method (planet passes in front of parent star) 5. Circumstellar Disks (measure dust cloud distortions caused by orbiting planets)6. Direct Observation with Spitzer
