Environment - Non Weather Related
[BNA] ILS 20L. Flight and majority of approach uneventful. We broke out of the clouds at about 700 feet on the approach. At the 500 feet call out; I observed a rather large party balloon along our flight path. I disconnected the auto pilot and maneuvered to the right to avoid hitting it. This maneuver was followed by a go-around due to the approach not being stabilized. I called for the go-around then we followed the missed approach. Individuals on the ground should find a better way to secure their party balloons.
CRJ-900 Captain reported executing a go-around from their approach to BNA after spotting a party balloon on their flight path at about 500 feet AGL.
