Giant planet around tiny star 'should not exist'

[Notebook]

Astronomers have discovered a giant planet that, they say, should not exist, according to current theories.
The Jupiter-like world is unusually large compared with its host star, contradicting a widely held idea about the way planets form.
The star, which lies 284 trillion km away, is an M-type red dwarf - the most common type in our galaxy.
An international team of astronomers has reported its findings in the journal Science.
