It was around 4:25 when my friends and i were looking out of our window in knoxville. they continued on with their game on the playstation and i noticed a little star in the sky-i thought- at least over a mile or two away. it was over an hour until sunset but that did not feel like the reason i kept wanting to look. i blankly stared at this star like object and as i looked it appeared to get much brighter and much larger in appearance as it emitted this bright white light. as this is happening, there is a crop duster plane in the are was flying before, during, and after the sighting. i know this was not any type of aircraft because they mostly have red reflective lights on the tails/wings. anyways, soon after this light became much brighter, it died down to literally nothing. i told my friends after it disappeared and told them to keep watching the sky just because i had a feeling something would move. i look over at the time at it was about 4:30, so i decided to look a little more. around 4:36 was when i saw a small dark grey object move from ne to n as the image of it slowly slipped behind a building. what was weird is it never came all the way out from behind the building. after it was gone it just disappeared.
