This reminds me of an incident on Friday night: I noticed an unusually bright planet in the sky, and checked it out with Google Night Sky on my Android phone. When I zoomed in, the software showed the disc of Jupiter overlapping with Uranus. I sure was amazed!

I checked now, and the planet conjunction list at http://en.wikipedia.org/wiki/Conjunction_%28astronomy_and_as... indicates that this conjunction has happened several times recently, but won't be happening for a while now.
