What does wanderer mean in space terms?

In space terms, a "wanderer" refers to an object that moves through space without a fixed orbit, often used to describe celestial bodies like asteroids, comets, or rogue planets. The term can also apply to planets in our solar system, particularly when referring to the five classical planets visible to the naked eye—Mercury, Venus, Mars, Jupiter, and Saturn—before the advent of telescopes. These wanderers contrast with fixed stars, which maintain their positions relative to one another in the night sky.
