Big green orb about 2o get wide and 20 feet tall hovered down from the sky and hovered it did not make a sound

I was outside working on a water line with my step son and son in law when the area became light up in a green glow, I looked up to my right and they did as well to see a 20ft by 20ft bright green orb descend down out of the sky and hover above a single wide mobile home, it hovered in 1 spot for 2 or 3 minutes with out making a sound as we walked closer to it then when we were with in 30 feet from it it started hovering slowly off to the right then with in a minute of that it took off and it was gone it didn’t make a single sound and was gone in out of sight within seconds, the middle of the orb was a lighter green and a darker green around the edges, I tried to take a picture of it but my phone would work and when it did it just took a picture of everything around looking green but no orb it was the same orb the spotted in Canada but with in 4-6 months after that my step daughter seen the same orb but at another property in Corbin with 4 miles or so from where I seen it
