Planetary System
In 1998 the California and Carnegie Planet Search team, after following a suggestion by Kevin Apps, a Briton who at the time was an undergraduate student found a possible planet orbiting the star. There were also indications of another, more distant body orbiting the star and this claim was published in 2006. This planet was confirmed in 2009.

“What is a television apparatus to man, who has only to shut his eyes to see the most inaccessible regions of the seen and the never seen, who has only to imagine in order to pierce through walls and cause all the planetary Baghdads of his dreams to rise from the dust.”
—Salvador Dali (1904–1989)
“Delight at having understood a very abstract and obscure system leads most people to believe in the truth of what it demonstrates.”
—G.C. (Georg Christoph)
