exoplanetary
Orbiting other stars
Exoplanetary means relating to or involving exoplanets—planets that orbit stars other than our sun.
The term appears in astronomical and scientific contexts: exoplanetary systems, exoplanetary research, exoplanetary atmospheres.
Most exoplanetary discoveries have come through indirect detection methods like observing how planets affect their host stars.
