Detailed explanation-1: -Why not circular? Orbits are eliptical because of Newtons Law of Gravity (bodies attract each other in proportion to their mass and inversly proportional to the square of the distance between them). All worked out by Kepler some years ago.
Detailed explanation-2: -Oort cloud comets do not orbit the Sun in the same direction as the planets, and orbits can be pointed in any direction.
Detailed explanation-3: -If the planet is large enough it can happen easily. Shoemaker Levy-9 was a comet that was captured by Jupiter and orbited it at least once, perhaps more than once, but given the highly eccentric orbit, perhaps only once.
