    nounA noun covering the path an object travels, as in a planet's or satellite's orbit; also 'trajectory'. Use this when talking about the orbit itself rather than the motion.
    その衛星えいせいは地球ちきゅうの軌道きどうを10周しゅうした。↗
    The satellite made 10 orbits of the earth.
  • 回るまわるJLPT N4approx.Common
    godan verb, intransitive verbA verb meaning to go around or circle; 'to orbit' is one of its senses, used when describing something actually revolving around another thing. For the noun, 軌道 is what you want.
    その船ふねは岬みさきを回まわった。↗
    The ship sailed around the cape.

Use 軌道 for 'orbit' as a noun — the path itself — and use the verb 「回る」 when you want to say something actually goes around or orbits something.
