Annus luce mensus^[1]^[2] (abbreviatio anglica ly)^[3] est illud spatium quod lux per unum annum in spatio vacuo pervolare potest. Unus annus luce mensus aequat fere 9 460 500 000 000 km. Longitudo exacta dependet a definitione anni (sive annus tropicalis sive annus Iulianus sive annus sideralis significatur). Unio Astronomica Internationalis annum Iulianum praefert. Itaque 1 ly aequat 9 460 730 472 580 800 m. Unum spatium lucis annuae aequat 63 240 ua (unitatum astronomicarum) vel 0,3066 pc (parsec).

Exstant etiam unitates

"hora luce mensa" (= 1 079 252 848 800 m),
"minutum luce mensum" ( = 17 987 547 480 m),
"secundum luce mensum" ( = 299 792 458 m).

Astronomi unitatibus spatii lucis ad distantias astronomicas metiendum utuntur. Terra, exempli causa, a Sole circiter octo spatia lucis minutalis abest. Proxima stella praeter Solem, id est Proxima Centauri, plus quattuor annos lucis abest.
