PLANETARY SYSTEM Meaning and
Definition
-
A planetary system refers to a collection of celestial bodies, primarily composed of planets and other smaller objects that orbit around a specific star, known as the central or parent star. This system is bound together by gravitational forces acting between the objects within it. The central star is typically much larger and more massive than any of the other bodies in the system, providing the dominant gravitational force that governs the motion of the system as a whole.
The planetary system generally consists of planets, which are large celestial bodies that revolve around the central star in elliptical or nearly circular orbits. These planets are often composed of solid matter, gas, or a combination of both, and possess various characteristics such as mass, size, and composition that distinguish them from one another.
Additionally, many planetary systems contain smaller celestial objects such as moons, asteroids, comets, and meteoroids. These lesser objects also orbit the central star and often have direct or indirect influences on the planets within the system.
Planetary systems are an integral part of the universe and are known to exist in abundance within galaxies. They offer scientists valuable insights into the formation and evolution of celestial bodies, as well as the potential for extraterrestrial life. The study of planetary systems and their dynamics is a significant area of research in astronomy and astrophysics.

Etymology of PLANETARY SYSTEM
The word "planetary" comes from the Latin word "planeta", which means "wandering star". In ancient times, planets were observed to move across the night sky differently from the fixed stars, hence they were called "wandering stars". The term "system" is derived from the Latin word "systēma", meaning "an organized whole". When these two words are combined, "planetary system" refers to an organized collection or arrangement of planets orbiting a central star.
