Triple sunrise
Science World, Oct 3, 2005 by Brandon Miller
On one newly discovered planet, if you were to miss the morning sunrise, you'd have two more chances to catch it.
That's because the gas giant--a Jupiterlike planet made mostly of gas--has three stars like our sun moving across its sky. "Such triple-star configurations are actually common," says Maciej Konacki, a planetary scientist at the California Institute of Technology. But this is the first time anyone has spied a planet among three stars.
This planet, located outside our solar system, orbits (circles) one of the stars at a distance that's about 23 times closer than Earth is to its sun. The trio's two smaller stars circle the planet and inner star pair. This setup heats the planet to a scalding 727[degrees]C (1,340[degrees]F). So life as we know it would be impossible, says Konacki.
