Creator Mike Kelt from Artem has previously said finding a new site for the giant structure "probably means a very large headache".

And that, Mr Kelt said, was "obviously the reaction we wanted".

Mr Kelt admitted to some "head-scratching" after being commissioned to build the bull.

Early targets for investigation include the so-called "Styrofoam world" Kelt 11b; the "lava planet" 55 Cancri e; and the "evaporating planet" GJ 436b.

Kelt 11b is a seemingly "puffed up" world with a very low density - hence the comparison with expanded foam.
