Gigglebutt (2021)

When an aging astronomer stumbles across a new inhabitable solar system, his hopes of going down in history are swiftly put on hold once he realizes a 6-year old girl has already named his astronomical discovery 'Gigglebutt.' The astronomer, Henry McConnell, travels cross country to rural Missouri to convince Aaron Pawson and his young daughter, Maisie, to sign over the naming rights, only to realize that his discovery is much bigger than himself and his legacy.
