It was a silver round disk with a dome centered ontop alot like the ones in the 1950s space movies

I was driving home from work with my young son around 5:00pm.
It was a clear day except for a few fluffy white clouds. On a heavy traveled road I pulled off because I had noticed a silver disk sticking only a little way out of the clouds above me..
I got out of the car and stared at the round silver disk..
there were no lights on the disk. The thing that surprised me was how much it looked like the saucers from those old 1950 space movies. There was a dome that was centered atop the disk that had a shield the closed after I was watching for several minutes The most scariest was the fact it was very close to me I could see it prefectly clear..Then it pulled into the cloudes and I drove home
Date is approximate.  PD
