It appears that binary planets exist beyond the solar system. That's according to the research made by a graduate student.
Daniella Gagliuffi presented her research on binary planets at the American Astronomical Society's summer meeting in San Diego in June with a detailed research on newly-found binary alien planets.
Seeker reported that the newfound bodies fare the same with one another in terms of size and age. A dividing line exists to demarcate the gas giants from odd failed stars - known as brown dwarfs in terms of mass, as the twin planets dance around a central point of mass.
"They're probably brother and sister," Gagliuffi said of the binary planets. The research shows those planets being held within a cluster of stars, pushing the planets close to one another. Any further interactions with other stars may forcefully push the planets closer.
Gagliuffi also found that the first-ever discovered binary alien planets roughly weigh between 14 to 15 times the mass of Jupiter - the solar system's largest planet. The research describes the objects as locatable within cloud of stars about 65 light years away from Earth. Also, she said that the pair is betwee 200 million and 300 million years-old.
"Their mass is straddling the deuterium-burning limit," Gagliuffi said.
According to Space, Gagliuffi noted that the twin alien planets drift amid a so-called "a whole zoo of different stars," for about 926 million miles apart, which counts for around 10 times the distance between the Earth and sun.
"Given that they're so close, it's extremely likely that they're bound," Gagliuffi added.
