OK, first, the planet: called PH-1, it’s bigger than Earth,
about six times our radius, or about half the diameter of
Jupiter. The mass isn’t well known, but may be as high as 170
times our own mass, though far more likely it’s closer to 20 –
50 times our mass. That makes it closer physically to Uranus and
Saturn than Earth, so it’s likely a gas giant. It’s also hot,
with a probable cloud-top temperature of 400+ Celsius (800+° F).
Even if it has Earth-sized moons they’re likely to be too hot to
be hospitable. And since it’s 5000 light years away, we’re not
headed there any time soon, anyway. But the more interesting
thing about this planet is its host stars: PJK-1 orbits a binary
star, two stars that orbit each other (like Tatooine, if you
like). Six other planets are known to orbit binary stars, but
PH-1 is even cooler: the binary star is itself orbited by
another binary pair much farther out, making it the first planet
found in a four-star system. So we have two stars orbiting each
other, orbited by a plane
