Yellowish/Orange sphere traveling across the sky.I was sitting in my boyfriend’s car staring up at the sky listening to him talk about something and then all of a sudden I saw this circular, orange/yellow, object moving across the sky. It lasted about five seconds and it was not a shooting star and it left sort of a trail of light behind it. I live it the city so it’s not dark enough to see stars or shooting stars, so it had to be something else. My first thought was that it was an airplane or helicopter but it was moving across the sky way too quickly.
