Planetary System
In 2007 a massive extrasolar planet was reported orbiting the star. The planet orbits Epsilon Tauri every 1.6 years in a somewhat eccentric orbit. At the time of the discovery it was the only known planet in an open cluster. No other planets have yet been detected in the Hyades cluster, but another planetary system—Iota Horologii— belongs to the Hyades stream and may be an escaped member of the cluster.

“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)
“It would be enough for me to have the system of a jury of twelve versus the system of one judge as a basis for preferring the U.S. to the Soviet Union.... I would prefer the country you can leave to the country you cannot.”
—Joseph Brodsky (b. 1940)
