The Oort Cloud 4 In 1950 Jan Oort noticed that mno comet has been observed with an orbit that indicates that it came from interstellar space, mthere is a strong tendency for aphelia of long period comet orbits to lie at a distance of about 50, 000 AU, and mthere is no preferential direction from which comets come.
