Something akin to obelisk from 2001 Space Odyssey has passed through solar system. The object has approached too fast to be from our solar system and has accelerated without ejecting gas like a comet on approach to sun. It passed within Mercury's orbit. It's ~800m long and shaped like flattened oval and is now on the way out from solar system.
