A planet with three suns

Researchers have spotted a super-Jupiter orbiting a star in a three-sun system at a distance twice as far as Pluto is from our own sun.

Preliminary data suggest that the gas giant—about four times the mass of Jupiter—orbits the largest and brightest of the three stars (which has about 1.8 times the mass of our sun) once every 550 years or so. The other two suns in the system, smaller stars that orbit each other relatively tightly and quickly, lie somewhere between 45 billion and 60 billion kilometers away. The intricate dance of the planet and these stars is taking place about 320 light-years from us. Measurements at near-infrared wavelengths suggest that HD 131399Ab’s atmosphere contains water vapor and methane, and that the planet’s cloud tops are about 850 K (577°C).
