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.

gollark: Simple decision trees *are* responding to/analyzing the outside world (well, game world), and I think some of the not-really-AI algorithms do an imagination-like thing of simulating various possible futures and picking the action which produces a lot of the better ones.
gollark: <@199529131224989696> I was thinking about stuff recently, and you know when you said `allow for introspection, imagination and probably also analysis of the outside world` when I asked `What does consciousness actually do, though?`Maybe you would need some form of consciousness, whatever that is, for introspection, but you don't for "imagination" and "analysis of the outside world". You can do those with simple "AI" like we use for games.
