Triton, Varungrah ke sab se barraa chandarma hae. Ii Varungrah ke khaali ekke chaand hae jon apne se golaa bhais hae aur isme atmosphere hae. Triton Varubgrah ke parikramaa grah ke rotation ke ultaa direction me kare hae, aur ii Saur Mandal me khaali ekke chandarma hae jon aise ghume hae. [8][9] Ii socha jaae hae ki Triton ek dafe ek bauna grah, Kuiper belt se hae, jiske Varungrah ke gravity pakarr liis rahaa. [10]
