Strange 'Twin' New Worlds Found
The planemo twins: Two peculiar planet-like worlds
A pair of strange new worlds that blur the boundaries between planets and stars have been discovered beyond our Solar System. A few dozen such objects have been identified in recent years but this is the first set of "twins".
Dubbed "planemos", they circle each other rather than orbiting a star.
Their existence challenges current theories about the formation of planets and stars, astronomers report in the journal Science.
"This is a truly remarkable pair of twins - each having only about 1% the mass of our Sun," said Ray Jayawardhana of the University of Toronto, co-author of the Science paper.
"Its mere existence is a surprise, and its origin and fate a bit of a mystery."
