I was travelling west towards hudson wi from my house in troy. i noticed a rapidly descending point of light in the direction of the msp airport; i often see aircraft in the area, but this was moving very quickly and in an unusual path. the light stopped and suddenly split with 2 additional lights moving away from the central light, which remained stationary. i immediately called my wife and told her about what i was seeing. i watched them travel until i reached my destination. i came out 5 minutes later and could not see the lights anymore. the lights appeared to be very far away, likely beyond msp airport, but i was unable to tell. i originally thought it was a plane, but it travelled in a very strange way.
