It's amazing that we receive information from afar.
Wahuuuuuu 149.6 million kilometers!

And I just checked an online source...

Pluto's perihelion (minimum distance from the Sun) = 29.7 AU
Uranus' aphelion (maximum distance from the Sun) = 20.07 AU

(1 AU or Astronomical Unit is the average distance of the Earth from the Sun, about 149,600,000 km.)

Thank you, Rob. I was almost 100% sure that Pluto didn't go inside the orbit of Uranus - but this image made me doubt my understanding! Of course - the tilt of Pluto's orbit explains it.

Pluto's orbit is tilted quite a bit with respect to the other planets. So I think what we see in that picture, which is a perspective view, is that the portion of Pluto's orbit which is below the plane of the other orbits just happens to look as if it passes inside of the orbit of Uranus. But if you imagine yourself moving up to a position directly above the solar system, you'd see that Pluto's orbit does not cross Uranus' orbit.

This simulated view from voyager helps with perspective, and does include pluto.

Why settle for a single still picture when we can have video?

You write the book, you make the slippers silver. You make the first color movie, you don't use slippers that will look like the came out of a black and white film. You supply your STAR with footwear which give her a little more glamor. Notice the reference to a star so we stay on an astronomy topic. :wink:

Yes. Something that has been borne upon me, since working the the lectures about the planets of our solar system on the Astronomy course that Robert Nemiroff has put on YouTube, is how extra-ordinarily beautiful and rich our own planet is.
That is very obvious and possibly sounds trite - but The Earth is a very precious place. The more I see of Elsewhere the more I realise that there really is No Place Like Home...

It''s not that bad. Pluto was near perihelion in 1990, and passed Neptune's distance from the Sun outbound almost nine years that date (I see one reference to Feb. 11, 1999). The statement refers to that circumstance rather than planetary definitions.

I had an undergraduate professor who asked the identity of the most distant known planet twice during one term in 1979, with the answer changing between exams. I cite this as evidence that I am not remotely as devious as some students believe me to be. Of course, I'd want them to think so anyway.

It's a shame Pluto didn't make it to this family portrait.
He's kind of the awkward cousin nowadays...
