Can somebody help me find this APOD?

[Ann]

A young colleague of mine has three little boys who love astronomy. I have sent them links to pictures of galaxies, which they loved. Now I would like to show them some interesting pictures of the Solar system (our solar system).

I think I can remember an APOD that showed all the known spherical objects in the solar system, to scale. I remember that I had to scroll right, and right, and right, as the solar system objects became smaller and smaller. I found this "visual list" fascinating, and I think that the little boys would like it.

So I've tried to find it. But although I kept googling, I couldn't find it.

Can anybody help me?

There have been a number over the years. The only fully interactive one I recall is https://apod.nasa.gov/apod/ap120312.html . There was also one where you could just scroll left and right to compare everything from planets up to the largest stars.

You don't need to limit yourself to APOD. Just Google "scale of the universe" or "scale of the solar system" and you'll get loads of links to videos and interactive apps.

Thanks, Geck, but no! I had actually already found that one. (And I have scrolled through it too, once, and I'm not going to do it again.)

No, the way I remember the picture I'm looking for, the planets, moons, asteroids and Kuiper Belt objects were crowded together and shown according to size, the biggest ones first. It looked something like this (warning! Large picture!), but there was only "one line of objects", stretching to the right almost into infinity (but not, obviously, as far to the right as joshworth's map of the Solar system). And there were many more objects there, too. And the space between the objects was literally zero.

I found it. It is this 7.27 MB picture.

Thanks to you, too, Chris, for your suggestions.
