5 spherical orbs seen floating in the skyI was outside with my wife when I looked up at a clear blue sky I noticed 3 white spheres in a 170 degree angle a few miles apart. The altitude was above planes but it looked like they were in our atmosphere. They gradually floated around the sky for several hours. When I went outside later to see if they're were there I saw two more. The two were very spaced out and the other three were still together. I noticed throughout the time they would get smaller and bigger probably changing altitutdes. Only one remained the last 30 mins the rest vanished
