Libration


Definition:

  • (n.) The act or state of librating.
  • (n.) A real or apparent libratory motion, like that of a balance before coming to rest.

Example Sentences:

  • (5) In the 1970s, Princeton physicist Gerald K O’Neill envisioned 100,000-person colonies, stationed at what is known as the fifth Lagrangian libration point (L5) in the moon’s orbit – like a gravitational eddy where things stay put by themselves.
