Title: The Terrestrial Search for ExoPlanets or Planetary Worlds orbiting other Stars.
Post by: Jonnie Goodboy on August 27, 2012, 12:07:39 pm
An extrasolar planet, or exoplanet, is a planet outside the Solar System.
By far most detections are made by 'Radial Velocity' variations to the sun which is centric to that planetary-system.

The latest NASA Exoplanet Archive image shows a total of 778 such planets (in 624 planetary systems, including 105 multiple planetary systems) have been identified as of August 24, 2012.
