A young “homeless planet”, up to seven times the size of Jupiter and with no gravitational ties, has been spotted by scientists for the very first time.
That must be up around the limit for planet size isn’t it? For at some point you don’t get a planet, gravity leads to a star?
Or, given that we’re talking about something very young here (120 million years old apparently) and thus something made out of old stars with much more of the heavier elements therefore, does that planet/star size change dependent upon said composition?
Who is the astronomer around here?
