Exoplanetary Scratchpad

[SysBP Img]

Near naked-eye star containing two planets, also known as HD 134987. The first is an eccentric giant at Venus-like distances and one of the first exoplanets discovered (1999). The second is a Jupiter analog (a = 5.8 AU, q = 5.3 AU, Q = 6.3 AU, e = 0.12, P = 14 EY, m = 0.8 MJ) discovered ten years later, indicating that enough time has passed to detect Jupiter-like planets.
