HOW COULD MEASURING THE ORBIT OF A COMET HELP SCIENTISTS UNDERSTAND WHEN IT WILL NEXT BE VISIBLE FROM EARTH?

Because comets, as planets, follow periodical orbits around the Sun. These orbitas are controled by KEPPLER'S LAWS. Use our Interactive Comet Animation to some things about how comets work.
Because comets follow periodical orbits around the Sun. As a comet’s orbit brings it close to the sun, we can see the tail. If we measure the orbit of the comet we will know the next time the comet is close to the sun.Also see Interactive Comet Animation about how comets work.
i think the same cause orbits are comets
