Stationary green light in the sky for about 3 minutes maybe longer, zipped all weird directions then descends down and disappears

I was taking out the trash at work to the outside dumpsters of the building facing south towards the coastlines and if followed in a straight path, would my guess be, past Delaware. Potentially out in the ocean in the sky. It was a green light that just sat in the sky for about 3-5 minutes and could have been there longer than when I first stepped outside and saw it. I questioned if it were a plane at first but realized it was impossible because there was a plane in the sky pretty further east and I actually was able to compare the two. Once I had finished with the trash, and keeping a close eye on the green light, it had started to zip left and right. It obviously had no indication of being a plane or even some sort of radio or cell tower given it had started to move and was really high in the sky. Higher than any tower man would probably build. I just stared in amazement and astonishment because I’d never seen anything like it before. It zipped left and right and I could just tell it was probably all these weird directions that any flying object know to the public wouldn’t be a plane. Then it almost just rapidly descended downwards and disappeared. My guess is it was probably in the ocean off the coastline of Delaware and potentially a little bit further east than that sprightly. Not east enough to be past Philadelphia.
