PLANETARY BODY Meaning and
Definition
-
A "planetary body" refers to any celestial object that is naturally occurring and gravitationally bound to a star or stellar remnant. It typically refers to the objects that exist within a planetary system, such as planets, dwarf planets, moons, asteroids, or comets.
Planets are the most well-known type of planetary bodies, characterized by their larger size and spherical shape. They orbit a star, like the Earth orbits the Sun, and do not produce their own light but instead reflect the light of their host star. Dwarf planets, on the other hand, are similar to planets in terms of their characteristics but may not have "cleared their orbit" of other debris, according to the criteria set by the International Astronomical Union (IAU).
Moons are smaller celestial bodies that orbit planets or dwarf planets. They may have formed alongside their parent planet or been captured by its gravitational pull. Moons have diverse characteristics, ranging from solid rocky surfaces to icy surfaces or even a mix of both.
Asteroids are rock and metal objects that orbit the Sun. They are generally smaller than planets and dwarf planets but larger than meteoroids. They are remnants from the early Solar System when planets and other objects were forming.
Comets are composed of ice, dust, and rocky materials. They often have a highly eccentric orbit and typically originate from the frigid outer regions of a planetary system. When a comet approaches the Sun, the heat causes the ice to vaporize, creating a glowing coma (a cloud of gas and dust) around the nucleus and sometimes a tail that points away from the Sun.
In conclusion, "planetary bodies" encompass a wide range of celestial objects within a planetary system, including planets, dwarf planets, moons, asteroids, and comets. They play a

Etymology of PLANETARY BODY
The word "planetary" is derived from the Latin word "planētārius", which means "pertaining to a planet". This Latin term, in turn, originates from the earlier Greek word "planētēs". The Greek word "planētēs" refers to a wanderer or a celestial body that moves across the sky.
The term "body" has Old English roots and comes from the Old English word "bodig", meaning "trunk" or "physical form". Over time, its meaning expanded to refer to the physical structure of living organisms or inanimate objects.
Therefore, combining "planetary" and "body" forms "planetary body", which refers to any celestial object or entity that is part of the solar system, such as planets, dwarf planets, moons, asteroids, or comets.
