Adjective

orbital (not comparable)

1. Of or relating to, or forming an orbit (such as the orbit of a moon, planet, or spacecraft).
2. (anatomy) Of or relating to the eye socket (eyehole).
3. (chiefly UK) (of roads, railways) Passing around the outside of an urban area.

   The M25 is an orbital motorway around London.

   • 2019 October 23, Rail, pages 22, 23:

     The rail orbital routes outside of the M25 and South Coast are challenging. The corridors aren't particularly reliable, and in some places they don't exist. [...] But the reliability and journey times, particularly on the orbital routes: one train an hour from Gatwick Airport to Reading? Surely we can do better than that?
