    Of course there are undiscovered comets out there, but for everything we know and can theorize – no. Comets are quite small compared with planets. Most comets measure between 750 meters to 20 kilometers in diameter. The earth’s radius is 6,378 km at the equator and the radius of the shoemaker comet which is visible when it passes has a radius of 4.5.
