White orb over I-85 in Durham NC early 80’s

I was a kid, and witnessed an orb like light over I-85 while traveling with family.  It was white. This was the early 1980’s so I was about 9 years old.  They didn’t see it but I was a kid and looking straight up into the sky.  It moved faster than I can explain. Nothing I have seen since to compare it too. It zoomed over the highway. Then came to a dead stop, about several hundred feet above the hwy.  within seconds it zoomed back off into the sky going upwards.  There was no sound.  Have never forgotten this moment.  I knew it was something out of the ordinary.
