Gamma Cephei A

Parent Star: gamma Cephei A (HD 222404) (K1 IV) in the constellation of Cepheus is located at a distance of 38.48 Light Years from our Solar system. Co-ordinates are Right Ascension: 23 39 20.8490 & Declination: +77 37 56.193. The apparent Magnitude of the star is 3.225. The Inner Edge of Habitability Zone is 1.69 AU & the Outer Edge of Habitability Zone: 5.27AU. Orbiting around gamma Cephei A is planet gamma Cephei A b is believed to be a Sulfurous Cloud Jovian and its exitence has been confirmed. The Planets Appearance is a Sulfur stained clouds of water or H2SO4. The planet is positioned at the inner edge of habitability zone at mean orbital distance of 2.029 AU and the planet Orbits around the star every 902.26 ± 6 Days and was discovered by COCHRAN W., HATZES A., ENDL M., PAULSON D., WALKER G., CAMPBELL B. & YANG S in Sep 2002.

Gamma Cephei A B Statistics

gamma Cephei b is the first planet discovered in a close binary star system. At their closest, the two stars are only 12 AU from each other, proving that such close systems can support planets. This discovery also ups the likely number of planets in the galaxy as most stars are in double or triple star systems.
