Aircraft
While flying VFR in cruise flight; the Emergency Exit door in Row 2 opened as we were approaching the south shore of the island. I told Approach that I needed to divert to the [nearby] airport. They handed me over to Tower. Not knowing what; if any; damage was done to the aircraft; or if any passengers were injured; I declared an emergency with the Tower. Once established inbound I checked on the passengers; who were all fine. We landed with no further incident.
When an air taxi CE-402 lost the emergency exit door in flight the Captain declared an emergency and diverted to a nearby airport.
