Exoplanets such as this one - situated in their stars’ habitable zone and massive enough to lasso in many rocky moons - could be an interesting place to go looking for signs of alien life.
The newly confirmed behemoth has been dubbed Kepler-1647 b, and it sits 3,700 light-years away in the constellation Cygnus. A light-year is nearly 6 trillion miles. At an estimated 4.4 billion years old, it’s roughly the same age as Earth. But it’s nothing like our home planet.
