Narrative:

Arriving phl on VCN8 arrival. On a 360 degree heading vector descending from 8000 ft to 6000 ft; 5 miles north of vcn as we were leveling to 6000 ft ATC reported unidentified aircraft above us. We only saw a dash 8 a 1000 ft below us. Suddenly we had switched to 10 miles range on display and saw a red dot display coming toward us. We both got our eyes scanning outside and then saw the twin beech red/white with an north side number directly in front of us 200 ft above us he was on a heading of 230-250 degrees. No evasive action was necessary because he was steady on heading and altitude. My hand almost disconnected the autopilot and I was prepared for any violent maneuver it might take. I don't think that he ever saw us. Very close!
