Planetary System
In April 2001, two giant planets were announced orbiting the star. The first planet HD 74156 b orbits the star at a distance closer than Mercury is to our Sun, in an extremely eccentric orbit. The second planet HD 74156 c is a long-period, massive planet (at least 8 times the mass of Jupiter), which orbits the star in an elliptical orbit with a semimajor axis of 3.90 astronomical units.

Famous quotes containing the words planetary and/or system:
“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)
“A religion so cheerless, a philosophy so sorrowful, could never have succeeded with the masses of mankind if presented only as a system of metaphysics. Buddhism owed its success to its catholic spirit and its beautiful morality.”
—W. Winwood Reade (1838–1875)
