An interesting discovery:
‘Planemos’ is a great word…
The pair belongs to what some astronomers believe is a new class of planet-like objects floating through space; so-called planetary mass objects, or “planemos”, which are not bound to stars.
They appear to have been forged from a contracting gas cloud, in a similar way to stars, but are much too cool to be true stars.
And while they have similar masses to many of the giant planets discovered beyond our Solar System (the largest weighs in at 14 times the mass of Jupiter and the other is about seven times more massive), they are not thought to be true planets either.
