Funny, I saw something similar a couple of weeks ago.
Was going out late evening, quick run to the shops. Noticed when getting into my car that there was a quite bright orange "star" on the upper right hand of one of the brightest stars we have on the night sky. (might be a planet, not too informed on that)
Anyways, I drove up to the main road, looked again, and noticed the orange "star" was now slightly to the left of the bright star. I hadn't seen it move, it just suddenly appeared there instead. When I finally got to the store, the orange light was gone, nowhere to be seen. All happened within 5 minutes or so.
I found it strange, but very very interesting of course!
