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.[1] 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.
