What are the changes occur to a comet during an orbit?
The Changes are the comet is revolving in the solar system, so that the comet may keep orbiting
How could measuring the orbit of a comet help scientists understand when it will next be visible from earth?
Answer: Some comet may certainly hit a planet; a few years ago, one hit Jupiter. Halley's comet, however, doesn't seem to be in an orbit that will make it crash into any planet, and it will most likely disintegrate before its orbit changes enough for this to happen, since comets have a fairly short lifetime.

The comet orbits the sun, just like planets orbit the sun. The comet has enough momentum to avoid falling into the sun, but, not enough momentum to escape the sun's gravitational pull. It's called an orbit, and countless items in the solar system orbit the sun. The comet is just one of thousands of objects that orbit the sun.
You're fishing for "comet", but the setup of your riddle is defective. -- A comet need not necessarily be in orbit around the sun. Its appearance may be a once-in-eternity event. -- A comet only has a 'tail' during the small portion of its orbit when it's relatively near the sun. -- The whole notion of a "tail" is misleading. That particular whatchamacallit always points away from the sun, so when the comet has rounded…
He didn't discover it. He did some calculations that suggested that a certain comet, seen during his lifetime, and three comets seen many years before, had the same orbit, and therefore were all probably the same comet. He also predicted that this comet would return in a certain year in the future. It did and it was named as Halley's comet, in his honour.
