What does orb mean?
An orb is a round or spherical body, with its strongest modern association being a celestial body such as the Earth, the Moon, or a planet. The word has a formal, sometimes poetic quality, so descriptions like “a fiery orb” or “the blue orb” convey grandeur or wonder more strongly than the ordinary terms “ball” or “globe.” In ceremonial and heraldic language, an orb can also represent royal authority or global sovereignty, as in the traditional symbol carried by a monarch. As a verb, “to orb” means to move around another body in a circular path, although “orbit” is more common in contemporary scientific and technical writing. Overall, “orb” is especially useful for describing objects that are both geometrically round and perceived as important, distant, or powerful.
A round or spherical object, especially a celestial body such as a planet or star.
"The planet was visible as a brilliant orb just above the horizon."
The word often has a literary, formal, or poetic tone. It is also used for a ceremonial symbol of royal authority.
To move in a circular path around a body or object.
"The spacecraft continued to orb the Earth while its systems were tested."
This use is uncommon in ordinary speech; “orbit” is the usual neutral verb.
The plural is formed by adding -s and is used for multiple spherical objects or celestial bodies.
"The telescope revealed several faint orbs beyond the planet."
From the Latin word for “circle” or “globe,” an orb has traveled from the heavens to the language of physics and even to royal symbolism.
