Neptune 1 year old today

[iceman (Mike)]

Well, 1 Neptunian year since discovery, anyway.

It's been 165 years since our discovery of Neptune, even though it was born around 4.5 billion years ago

Some great images of Neptune, its rings and Moons, taken by Voyager here:

Yep, Happy Birthday Neptune

And who's to say it wasn't born (finally accreted) on this day all that long ago!!!

Shouldn't that say "1 Neptune year since discovery" though Mike?.....

I remember watching the live telecast on the ABC in 1989 on Quantum hosted by (blonde female presenter husky-voice - cannot for the life of me recall her name). From memory that broadcast is archived in the National Film and Sound Archives.

Happy Birthday Neptune.

Woops, have corrected. Thx

Thanks Mike,

Nice piece of trivia and gives some sense for how long the orbits of the outer
planets take.

It's discovery, predicted by observations of perturbations in the orbit of Uranus, was a triumph of the power
of mathematical models in describing physical laws of nature.

… the first 'Dark Matter' ever discovered eh ?
