The object appeared to be just above the tree line, it had 2 very bright green balls of light on it, not LED green, but a weird milky/mint like green.
It was hovering/floating and was silent. No flashing/blinking lights.
No red lights, like known aircraft.
There also appeared to be smaller lower strength white light/lights on the opposite side of the object when we drove by it on the highway.
Object appeared large and stationary.
