saw a green segmented object slowly traveling thru the sky

my daughter and i saw what appeared to be what i can only describe as a sparkler in the sky. the object changed direction and headed east and as it came in to view the craft appeared to be three section that where linked like semi trailers would be. the sections glowed green that my wife described as "like a glow stick" the three sections had what appeared to be dark black struts holding the frame of the craft together. the craft also had a metallic, and for lack of a better term, "cab" that seemed to be pulling the object. the object seemed to be in no hurry and we watched the object until it disappeared from view behind a stand of trees.
