ORBIT - the (circular) path described by one celestial body in its revolution about another 

ORBITAL - a mathematically described region around a nucleus in an atom or molecule that may contain zero, one, or two electrons 

so in simpler terms, an orbital is a region around a nucleus that may contain electrons and an orbit is the path around for example, the moon.
Orbit: is the path of electron around the nucleus.
2.these are represented by l,m, letters. is two-dimensional. does not satisfy Heisenbergs uncertainty principle.

orbital: is the probability of finding electron around nucleus.
2.these are represented by a,p,d,f,....'s information is given by orbital quantum number. is three-dimensional. satisfies the he Heisenbergs principal of uncertainty.
