can any celestal body or anything rotate at speed of 90 degree per second with a radius of
of more than or equal to 3 X 10 ^ 8 metre ?
is it possible?

ok guys
suppose a body or something with radius of more than or equal to 3X10^8 meters is rotating at speed of 90 degree /sec : then a point at crust of top layer will travel at speed of 3√3 X10^8 m/s (using pythagoras theoram ) so have i done anything wrong please correct me ?
thank you

Arithmetic may be correct, but it would be physically impossible.
