UFOs disguised as stars, dart past window.

My partner woke me up at 3am telling me he saw stars move. While looking out the window, we saw one star slowly move toward the centre of town. It has the same luminosity as a star, and it looked quite far away. Laying back in bed we talked for around 30 minutes, he had his back turned to the window. When suddenly a ball of light shot across the window, it's distance would only have been a few metres.
The shape was ball like, and it shone brightly but it appeared to be some sort of artificial light similar to led asnothing around it was affected by the light. Shaken we did not look out the window until 20 minutes later, when we noticed three other bright stars had disappeared.
