In any given year,about a dozen known comets come close to the sun in their orbits.The average person can’t see them all,of course.Usually there is only one or two a year bright enough to be seen with the(35)eye.Comet Hale-Bopp,discovered in 1995,was an unusually bright comet.Its orbit brought it(36)close to the Earth,within 122 million miles of it.But Hale-Bopp came a long way on its earthly visit.It won’t be back for another four thousand years or so.
