Depends on what you consider the solar system. Long-period comets are thought to come from the Oort cloud, of thousands of AU out. But since these bodies are under the Sun's gravitational influence, they are already part of the solar system. But if you consider the solar system to extend only as far out as Pluto (or Neptune), then no doubt several comets entered that realm in 1951. I found two long-period comets discovered in 1951 referenced; there may have been more: C/1951 C1 Pajdusakova and C/1951 P1 Wilson-Harrington.
