In 2005, the existence of 55 Cancri e was questioned by astronomer Jack Wisdom after reanalyzing the data. Wisdom claimed that instead there was a [[Neptune]] sized world orbiting 0.78 AU away. A new analysis was done in 2007 discovering that both worlds existed, the latter now deemed as 55 Cancri f, which was announced on November 6, 2007.
