3 White lights looked like star moving 3-5 mins apart in sky over Pleasant Hill, LAMy wife and I were at a friend of ours house I was looking up at the stars and noticed what looked like a star moving. At first I thought it was an airplane but noticed it had no flashing lights like an airplane. I also noticed it was moving to fast to be an airplane. I pointed out to my friend and my wife we continued to watch it move across the sky hen after a few seconds it disappeared. We saw 2 more pas by on the same path each on was about 3-5 mins apart. Was very strange. The lights appeared to be traveling south.
