What is the definition of a planet regarding its orbit?

The definition of a planet regarding its orbit states that it is a celestial body that has cleared the neighborhood around its orbit. This means that a planet has become gravitationally dominant in its orbital zone, effectively removing or accumulating other debris and smaller objects within that region. This characteristic is part of the current definitions established by the International Astronomical Union (IAU) and helps distinguish planets from other types of celestial bodies, such as asteroids and dwarf planets.

By having cleared its orbit, a planet demonstrates its significant mass and gravitational influence, which impacts nearby objects. This clearing process allows for a stable orbit and a typical planetary environment, contributing to the classification of a planet within our solar system and beyond. Other options either do not capture this essential defining feature or misrepresent the qualities that qualify a celestial body as a planet.
