HD 17092 b is an extrasolar planet located 355 light years away in the constellation Perseus, orbiting the giant star HD 17092.

Discovery

In 2007 discovery of an extrasolar planet orbiting HD 17092 was announced by a team led by Andrzej Niedzielski of Polish Nicolaus Copernicus University and including astronomers from Penn State, the Spitzer Science Center, the Jet Propulsion Laboratory, and the University of Texas.Cite journal | first = A. | last = Niedzielski | coauthors = Konacki, M.; Wolszczan, A.; Nowak, G.; Maciejewski, G.; Gelino, R.C.; Shao, M.; Shetrone, M.; Ramsey, L.W. | title = A Planetary Mass Companion to the K0 Giant HD 17092 | journal = arXiv.org | date = May 7, 2007 | url = http://www.arxiv.org/abs/0705.0935] The discovery was made using the Hobby-Eberly Telescope.

Characteristics

The planet, designated as HD 17092 b, has a minimum mass of 4.6 Jupiter masses. The mean distance of the planet from the star is more than distance between Earth and the Sun at 1.29 AU, and the eccentricity of the orbit is mild at 0.166.

Because of its high mass and gravity, the radius would probably be slightly smaller than Jupiter. Its speculated that it would have temperature of 402 K, which would make this planet a (Sudarsky type III), meaning that this planet would be blue and cloudless.
