		#autoLOC_CustomAsteroids_OPM_BlurbKentaur = Kentaurs are icy bodies that have been pulled into the outer solar system by the gravity of Neidon and the other giant planets. Some of them show cometary activity and many may eventually become short- or intermediate-period comets, but for now they orbit beyond Jool.
		#autoLOC_CustomAsteroids_OPM_SciKentaurExperiment = Kentaur Sample
		#autoLOC_CustomAsteroids_OPM_SciKentaurSample = This Kentaur has remained relatively untouched since its ejection from trans-Neidonian space, and will help our scientists get a better look at conditions in the outermost regions of the protoplanetary disk. You're just glad you don't need to go all the way out to the Kuper Belt.
