A Triple Play :)
That imaging paints a picture of a fairly unique world. HD 131399Ab is thought to be a gas giant, about four times the mass of Jupiter, with water and methane in its atmosphere. And its orbit is astonishing to the researchers. It travels around one of the stars in the system at a distance that’s about twice that of the Sun and Pluto, an incredibly wide orbit that lasts 550 Earth-years. For most of that time, the planet has a routine daytime and nighttime, as the three suns rise and set close together. But as the planet moves throughout the system, there comes a time when one sun rises just as another sets. This leads to a period where HD 131399Ab is bathed in constant sunlight — an interval that lasts 140 years.
As often said, you cannot make this up.
