I was driving northbound in Lombard, IL when I noticed a white-yellow “foggy fireball” like object. It was traveling northbound as well but then just stopped and hovered. It disappeared into thin air after hovering for a few moments. I kept an eye out to make sure it wasn’t an airplane but there was no airplane in sight. After driving a few more minutes northbound I noticed a really bright close “star” like object hovering which also disappeared into thin air.
