I was leaving for work this morning at 6:25. My wife walked with me to our back door to help catch any of our six kittens that try to get in the house every morning. I had my face towards the back door talking to my wife. I was on the third step and she leaned down to pick up one of our kittens. I asked her did she see Hercules, as I turned around to look towards my car to hunt the cat, I noticed a bright green glow. I saw a solid, perfectly round orb shooting across the sky. The orbs light lite up the shy and highlighted the cloud around it. I know it was under the clouds because it outlined the clouds with it's light. There was no sound and I had a clear view of the object. From my viewpoint it was about the size of a baseball. It moved for about 6 seconds and completely disappeared. I was stunned and when I turned to my wife, she said that she only saw a flash kind of like a falling star. She was petting our cat and I was in front of her, so she did not see the object like I did. I was excited and freaking out a little because I believe in UFO's but have never seen anything remotely close to a UFO. I do not know what this was, but it was not flickering like a burning object falling to the earth. It was a solid green orb. It's shape remained the same size and it's glow was consistent. It just disappeared and was gone.
