ask one idiot or should i say Mr grump
Long period comets (orbits of more than 200 years) are thought to have originated in the Oort cloud.
Through space. Comets have a period in which they orbit the Sun in an elongated ellipse, some have long periods, e.g. Halley's Comet, 75 years.
Long-period comets have periods of over 200 years.The longest would probably be somewhere around a million years (comparable to the orbital periods of objects in the Oort cloud); much longer than that, and it will go away far enough to be captured by the gravitational field of other stars.
Typically, several comets are spotted every year.
