A strange pair indeed, Neptune and it’s largest moon, Triton, were probably not formed together. Triton’s orbit about Neptune is retrograde, opposite Neptune’s rotation. Triton was probably a Kuiper belt minor planet captured by Neptune. Neptune’s axis of rotation is tilted 28 degrees to it’s orbit plane, and with a very long “year” to orbit the Sun, each of its four seasons is 40 Earth years long. Acrylic on stretched canvas, 20″ x 16″.
