The extrasolar planet, designated as HD 179949 b, was the first discovery by the Anglo-Australian Planet Search at the Anglo-Australian Observatory. The planet is a so-called "hot Jupiter", a Jupiter-mass planet orbiting very close to its parent star. In this case, orbital distance is almost tenth that of Mercury from the Sun. One orbital revolution lasts only about 3 days.

HD 179949 b's parent star is HD 179949.
