Round lighted object seen in Connecticut

Me and my mom were driving home when suddenly a rounded object with lights appeared in our view. we watched it thinking it was an airplane but the lights did not blink or strobe. As we were looking at it it got lower to the point where our car actually went ahead of the object ( this is how i could tell it was low because if it was high like an airplane we wouldn't have been able to pass it and to where the angle we had to look at it had to change ). We stopped, now questioning what we were seeing. The object continued to move past us ( to my view it was moving to my right and I was sitting in the passenger seat of the car, looking out the drivers side window ) until suddenly, and i mean INSTANTLY, stopped and shot away into the other direction ( away from our car, to the left of my view, and towards the rear of where our car was faced ).
