Orange glowing, black center wing

Orange glow perimeter, center being black or translucent.  It was not a rectangle but was like a wing with no tail or nose.  Like a butterfly wing shape but without the 3rd & 4th wing   This appeared so fast.  It glided, but at an incredidble speed. It travelled straight across sky.  At the height i am guessing at would be towards upper atomosphere or satelite orbit height.  Size wise is hard.  From that distance it would have to be huge!  Satelites are dots, this had shape.  I would have to say that take mars in the night sky and place 8 to 10 side by side to roughly get its size for that distance.  But when you see satelite dots orbit the earth its self explainatory.  This shot straight across for 6 seconds which came from around the moon area flew over my head (area) and lost it in the clouds that were forming.  Having given guessed altitude, i could be wrong or right?  I did not pay enough attention to height.  It was silent so i figured it was higher than normal planes would fly.  Most amazing thing i have ever seen.
