Major Planet - English Definition & Meaning

Definition

A major planet is a planet that dominates its region of space by either gravitationally clearing away, or capturing, all other objects in its vicinity. In our solar system, there are eight major planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. These planets have enough mass that gravity makes them roughly spherical. They've swept their orbits clean of similarly sized objects. They're the big players in our solar system 🏆. They are the stars of the cosmic show.

Etymology

The term 'major planet' arose from the need to differentiate between larger, dominant planets and smaller celestial bodies. Historically, as more objects were discovered in our solar system, astronomers sought to classify them. 'Major' simply signifies their greater size and gravitational influence. It's a way of organizing the cosmic neighborhood 🏘️.
