Universe - Version 5.2 There are (1-10) "planets" in orbit, and 3 are in "Comet" zones (ellipses). "Comets" according to the laws of physics,begin to gravitate toward the "planets" and their orbits will be altered. At the same time they leavea trail (so-called tails), that trace varying curves through the sky.There are (1-10) "planets" in orbit, and 3 are in "Comet" zones (ellipses).
