Description

Animation of 1 day (Sept. 8 / Sept. 9. around 22:00 UTC) movement of Neptun

(incl. rotation of it's moon Triton) against the background stars.

Rotation period of Triton is 5 d, 21 h, 2 min, 53 s (retrograde)

P.S.

I am convinced this "blinking method" is the only way to really proof that Triton was captured and

not accidently a background star. Please also notice a tiny different distance of Triton to Neptun

between both images. This complies with Tritons small ellipsoid orbit around Neptun.
