What is the term for the nearly circular path a smaller object travels around a larger object?

• A. Pattern
• B. Moon Phase
• C. Moon
• D. Orbit

Answer: (D)

An orbit is the path a smaller object follows around a larger one under gravity. When the object moves at the right speed at a suitable distance, gravity acts as the centripetal force that bends the trajectory into a circle-like path, keeping the smaller body bound to the larger one instead of falling in or escaping. This is exactly what we see with the Moon orbiting Earth or satellites circling planets. The path can be circular or nearly circular (a circular or near-circular orbit), though real orbits are often elliptical with low eccentricity. The other terms don’t describe the motion itself: a pattern is just a design or arrangement, Moon phase describes how the Moon’s appearance changes from Earth, and Moon refers to the object being orbited rather than its path.
