Narrative:

Upon our descent into ewr; we had just crossed over the new jersey shoreline and were approximately 10 miles north of mcguire AFB at 6;000 feet. At that time I noticed a metallic glint at about our 1 o'clock position. I asked the first officer if he saw it as well; and he said he did. At 250 KIAS; it closed on us fairly quickly but it kept glinting in the sun so we were able to track it. As we approached it; it seemed to look like a small balloon; but as it went down the first officer's side; he said it was a 2-3 foot in diameter drone. It passed about 300 feet or so to our right headed east and about 300-500 feet below us. We immediately reported the incident to ATC so that they could make the position. No other aircraft mentioned seeing this object anywhere in our area. The rest of the flight was completed without incident.
