Scientists baffled by rogue planet growing at a record rate

A rogue planet 620 light-years from Earth has baffled scientists as it puts on a record-breaking 'growth spurt'. In a months-long feeding frenzy, the planet hoovered up six billion tonnes of gas and dust every second. The distant world, officially known as Cha 1107-7626, is located in the Chamaeleon constellation and is what scientists call a 'rogue planet'. This means it is a free-floating mass which drifts through space by itself , rather than orbiting a star like Earth orbits the sun.
