Which of the following show periodic movement?
A
Comets and planets
B
Planets and Asteroids
C
Meteors and Comets
D
Meteorites and Comets
Explanation: 

Detailed explanation-1: -Some exist in a wide disk beyond the orbit of Neptune called the Kuiper Belt. We call these short-period comets. They take less than 200 years to orbit the Sun. Other comets live in the Oort Cloud, the sphere-shaped, outer edge of the solar system that is about 50 times farther away from the Sun than the Kuiper Belt.

Detailed explanation-2: -They are both celestial bodies orbiting our Sun, and they both can have unusual orbits, sometimes straying close to Earth or the other planets. They are both “leftovers”-made from materials from the formation of our Solar System 4.5 billion years ago.

Detailed explanation-3: -Comets are cosmic snowballs of frozen gases, rock, and dust that orbit the Sun.

Detailed explanation-4: -The short-period comets are found near the ecliptic, which means they are orbiting the Sun in same plane as the planets. The short-period comets are thought to originate in the Kuiper Belt, an area outside Neptune’s orbit (from about 30 to 50 AU) that has many icy comet-like objects.
