Narrative:

On climb out from runway 1R at sfo for the TRUKN2 near tydye (over the bay) at approximately 4700 ft MSL; I witnessed an object to the right of the windscreen that appeared to be hovering. When we got closer to it; the object looked like a mid-size drone similar to a dji inspire 2 quadcopter (I googled drones after the flight and this one looked the closest). I reported it to ATC when I saw it and they reported it to the trail aircraft. I flew F-16s up until a year ago where we routinely flew formation at 50-500 feet away from each other; so I consider myself to have a good gauge of aircraft distances. I estimate we passed within 500 ft from the drone since I was able to spot it and note details on the shape and size.
