HD 100777 b is an extrasolar planet located approximately 172 light-years away in the constellation of Leo, orbiting the star HD 100777. This is a >1.17 MJ planet taking 33.15 Ms to orbit at 154.1 Gm or 4.99 μpc from the star at 36% eccentricity. The velocity of the orbit is 29.3 km/s. Dominique Naef discovered this planet in March 2007 by using HARPS spectrograph located in Chile.

  • HD 100777 b is an extrasolar planet located approximately 172 light-years away in the constellation of Leo, orbiting the star HD 100777. This is a >1.17 MJ planet taking 33.15 Ms to orbit at 154.1 Gm or 4.99 μpc from the star at 36% eccentricity. The velocity of the orbit is 29.3 km/s.

  • HD 100777b ist ein Exoplanet, der den orangen Zwerg HD 100777 alle 383,7 Tage umkreist. Auf Grund seiner hohen Masse wird angenommen, dass es sich um einen Gasplaneten handelt.
  • HD 100777b是一颗位于狮子座、距离地球约172光年的系外行星，其母星为HD 100777。该行星的质量下限为1.17MJ，其轨道周期为3.315×10秒，其轨道距离中央恒星约1亿5410万公里，轨道离心率为0.36。该行星的轨道速度为29.3公里/秒。2007年3月，多米尼克·纳伊夫在智利通过高精度径向速度行星搜索器发现了该行星。
