"Wandering stars" is an expression that is often used to refer to planets. However, there are several synonyms that can be used to describe these celestial bodies. One commonly used term is "planetary wanderers", which emphasizes the fact that they move independently of the fixed stars. Another synonym is "erratic stars", highlighting their unpredictable movements across the night sky. Similarly, "roaming stars" or "vagabond stars" convey a sense of movement and instability. "Orbital bodies" or "celestial bodies" are more technical terms that can be used to refer to both planets and other non-stellar objects in space. Ultimately, the choice of synonym depends on the intended tone and context of the text.
