Large redish-orange sphere that slowly desended outside our house.

This was something that took place years ago when I was a child,but I'll never forget it.I think of it almost daily. I lived in rual west Tennessee. It was summer and we had no air conditioning, so we slept with the windows up. We had just gone to bed around 9 p.m.. My brother and I shared a room and we had not gotten to sleep yet. We noticed in the upper right-hand corner of our bedroom window that there was a strange redish-orange glow. It was gradually getting larger and larger. As we looked out the window, we saw a large sphere shaped object slowly desending. It seemed to be going down into a pasture between our house and my uncle's house about a quarter mile away. This thing  glowed with redish-orange light so bright that it light up our room like it was daylight. It took around ten minutes for it to disappear...then every thing was dark again. My parents also saw this and my uncle's son,whose bedroom faced our house. We went out the next day to see if we could find any sign of the object,but found nothing. There may be a logical explanation for this,but I have not as yet found one. It still haunts me to this day.
