Want to take a relaxing interstellar vacation? Consider visiting Kepler-16b, a world in a binary star system. In fact Kepler-16b is the first discovered circumbinary planet. It was detected in a wide 229 day orbit around a close pair of cool, low-mass stars some 200 light-years away. The parent stars eclipse one another in their orbits, observed as a periodic dimming of starlight. But Kepler-16b itself was discovered by following the additional very slight dimming produced during its transits. Like sci-fi planet Tatooine of Star Wars fame, two suns would set over its horizon. Still, Kepler-16b is probably not a Tatooine-like terrestrial desert world. Instead, Kepler-16b is thought to be a cold, uninhabitable planet with about the mass of Saturn and a gaseous surface … so plan to dress accordingly. Or, choose another Visions of the Future vacation destination.

想享受一個放鬆嘅星際假期？考慮訪問 Kepler-16b，呢個位於雙星系統嘅星球。事實上，Kepler-16b 係第一個被發現嘅環繞雙星行星。佢係透過環繞一對距離約200光年的冷卻低質量恆星，以229天嘅寬軌道被探測到。母星在其軌道中會互相遮蔽，觀察到定期的星光暗淡。Kepler-16b 本身係透過追蹤其過境期間產生的輕微額外暗淡來發現的。就如《星際大戰》中虛構的Tatooine星球，兩顆太陽都會在其地平線上落下。然而，Kepler-16b 可能並唔係一個像Tatooine咁嘅沙漠星球。相反，Kepler-16b 被認為是一個寒冷、無法居住的行星，質量大約與土星相似，並擁有氣體表面……所以計劃著衣要相應配合。又或者，選擇其他未來願景假期目的地吧！
