Hale-Bopp's current orbit brings it into the inner solar system about every 2500 years.
It's theorized that all comets formed in the Oort cloud, which is a spherical cloud of comets roughly 50,000 AU from the sun. Out there are temperatures sufficiently cold enough to form the giant balls of ice we call comets
No. Hale-Bopp is a comet. Comets are much smaller than planets, and travel in very eccentric orbits. This means that they come fairly close to the Sun at perihelion, and then retreat to great distances.
The Oort Cloud
Comets are named for their discoverers. Astronomers who are comet-watchers (a large percentage of comets are discovered by amateur astronomers) live and work in the hopes of finding a comet and writing their names in the heavens. For example, the comet that struck the planet Jupiter was named for the two discoverers, Shoemaker and Levy.

Sadly, no. Dinosaurs are distinct so they will not come back to earth.
Ghosts come back to earth to visit their house or to do things that they didnt finish. Ghosts probably come back to visit someone that they loved.

The Oort Cloud
The moon always keeps the same "side" facing Earth, which also means that the other half of its surface is always facing away from Earth. The only ways to see that side are: -- Send a robotic spacecraft to orbit the moon. Have it photograph the back side when it's there, and then send those photos to Earth when it comes back around to our side. -- Send people in a spacecraft to orbit the moon. Have them photograph the back side when they're there, and then send those photos to Earth when they come back around to our side, or else save them up and bring the photos back to Earth with them.
the earth isn't really going to 'end.' Jesus is going to come back and take his believers to Heaven and make a new heaven and a new earth
Apollo 13 came back to earth on the 17th of April 1970.
