HD 74156 System

Exoplanetary Scratchpad [SysBP Img]

Sunlike star with two planets more massive than Jupiter, one in about Mercury's position, and one at an Asteroid Belt-like position. A planet was predicted in between these two at Earth-like distances and later found, the first vindicated prediction since Neptune. This supports the "Packed Planetary Systems" theory. Some have suggested that it's one Earth year orbit period may mean its detection is due to Earth based observation errors.
