What you're seeing is a lens flare of swamp gas from a weather balloon trapped in a thermal pocket that is reflecting the light from Venus.
I don't see how you can argue against it being a star while pushing for the idea that it is a planet *not already known about* that is close enough to
be seen with the naked eye, to be honest. Tonight I could see Jupiter very clearly in the sky and it was right next to the moon.
