Where do comets come from?

The solar system is surrounded by a giant cloud of comet nuclei, which is named after the Dutch scientist J. Booth, who proved its existence in 1950. Comets move in extremely elongated orbits, and comets spend most of their period in the vicinity of their aphelions. The boundaries of the cloud are assumed to be at a distance of 20 to 200 thousand AU. from the sun. In addition to this outer layer of comets, there is also an inner layer beyond Pluto’s orbit. Its inner border is at a distance of no more than 2 thousand AU.
