Close encounter with UAS. I was heads down programming a newly assigned STAR into the FMS when I saw an object that I assumed to be a helium balloon whiz by the left side of the wing in my peripheral vision. The private pilot I was instructing immediately exclaimed 'that was close!' He stated that the object was some sort of multi rotor drone with a center unit around the size of a beer can and had nearly hit us. I immediately reported the incident to ATC.
Corporate jet instructor pilot reported a close UAS encounter at about 7;000 ft near the LOOSN waypoint on the LAS SITEE 1 RNAV Arrival.
