It was a bright green round glowing object falling very slowly then disappeared behind a ridge line.

I was on the phone with my sister while standing outside and suddenly saw a bright green glowing object which fell slowly through the clear dark sky before disappearing behind a ridge line. I did not see it come back up, so I believe it landed. I could not tell exactly how far away it was but I would say less than a mile. I was shocked by the sighting and noted how oddly slow it fell and what a bright glowing green color it was. Nearby outdoor dogs began barking after I lost sight of the object.
