it all happened within 3 - 5 seconds and did not change speed, it just glided along.

i was out on my driveway smoking a cigarette with 2 of my friends, however i was the only one facing down the driveway. i noticed something in the air that i  initially thought was a torchbug, but when i focused on it i noticed it was an eclipse looking sphere that was about 150 to 200 feet in the air just hovering steadily from south to north at a steady "Glide". i sidestepped on the driveway to get a split second more just to confirm with my eyes what i was seeing. it then vanished behind a tree that obstructed my view. the object looked like a small eclpse with a faint orange glow with a slightly stronger glow in what seemed like the bottom left corner (from my point of view) it was totally silent.
