Cruithne

Cruith·ne

C5806850 (krĭth′nə, krĭn′yə)n.1. An asteroid that orbits the sun in just over 365 days in a highly eccentric and inclined elliptical orbit that periodically brings it close to Earth. Earth has a strong gravitational influence on Cruithne, but the inclined orbit of the asteroid precludes a collision between the two bodies and also the possibility of Cruithne ever orbiting Earth as a second moon.2. (used with a pl. verb) The Picts.

[Old Irish Cruithne, the Picts (the asteroid being named by Duncan Waldron, the Scottish amateur astronomer who discovered it in 1986), from Cruithen, a Pict; see k^wer- in Indo-European roots.]
