## ››Definition: Light-day

A light day (also written light-day) is a unit of length. It is defined as the distance light travels in an absolute vacuum in one day (of 86,400 seconds) or 25,902,068,371,200 metres (~26 Tm).

Note that this value is exact, since the metre is actually defined in terms of the speed of light. The light day isn't very frequently used at all since there are few astronomical objects or distances of that magnitude; the Oort cloud, for example, is thought to extend between 290 and 580 light-days out from the Sun.

## ››Definition: Smoot

A smoot is a unit of distance (or "length", as physical scientists say) used for measuring the Harvard Bridge. It is named after an MIT fraternity pledge at Lambda Chi Alpha fraternity, Oliver R. Smoot (class of 1962). In October of 1958, fellow students helped Mr. Smoot measure the length of the bridge by placing him end to end and marking the increments. Oliver was a top student at MIT and went on to run NIST, the National Institute of Standards and Technology. The smoot is equal to his height (five feet and seven inches -- 1.70 m), and the bridge's length was measured to be "364.4 smoots plus one ear".
