orbit

Imagine the Earth circling the sun: that is an orbit. Most often, the word means the curved path one object follows around another, especially in space. A moon orbits a planet, and a satellite orbits Earth. The same idea can also be used as a verb, so you can say that a spacecraft orbits the planet.

But the word is not only about space. It is also used in a figurative way to talk about people, groups, or activities that stay close to someone important or are shaped by that person's influence. A journalist might write about the people in a president's orbit, or say that a young artist has entered the orbit of a famous musician.

The word "orbit" most commonly refers to the curved path that one object follows around another in space. Think of the moon orbiting Earth or Earth orbiting the sun. This movement is controlled mainly by gravity, which keeps the moving object from flying away in a straight line. For example, the International Space Station stays in low Earth orbit as it travels around the planet.

The word can be a noun or a verb. As a noun, it names the path itself: a planet has an orbit. As a verb, it describes the action: a planet orbits a star. This is the meaning people usually learn first, and it is the clearest and most common use.

Orbit is also used figuratively. In news, business, and everyday writing, it can mean a sphere of influence or the group of people connected to someone important. A politician's orbit may include advisors, donors, and supporters. If someone moves into a celebrity's orbit, they have become part of that person's social or professional world.

Sometimes the figurative use suggests staying near a person, idea, or activity without fully becoming part of it. A minor public figure might orbit a more famous one, always nearby and affected by that person's attention and power. In all of these uses, the central idea stays the same: movement around a center, either in a physical sense or in a social one.
