At least I could use that arrow on my scroll bar. I got as far as Mars, got the idea, and decided that was good enough.
That was fun........for about a minute....okay 30 seconds.
I remember a Utube video, where some astronomer said something like, "OK, suppose the Sun is this pea. I'll put it on the ground, and ride my bike to Earth." So he gets on his bike and pedals down the road a couple hundred yards, and says, "OK, now I'm at the Earth." Well, it was something like that. I can't remember if it was pea or two hundred yards, or a half mile, or a mile, but I got the idea.
I cheated, and just dragged the bottom scroll thingy 'til I got to Pluto...didn't take so long that way.
I stumbled upon this site years ago. There are shortcut tabbed links at the top of the page, the 10 icons within the 2 arrows.

I found this, but not a video yet:
If Earth were the size of a pea (https://h2g2.com/entry/A3005984)
"true to scale", wouldn't it take me years to scrolls to reach certain points?
I too cheated, and got to pluto.
Did read everything along the way.

In just the solar system? No. Hours at the most, at the speed of light. Even the Voyager probes, which are now just entering interstellar space, are only about one light-*day* distant.
Edit: I wasn't planning to go look it up, but I just stumbled across it. After 40 years in space as of September 5, Voyager 1 is now whopping 19.285 light
hours from Earth. That's all, not even a whole light day. After traveling for forty years, currently at about 38,000 miles an hour. Ten and a half miles a
second.
Space, as Douglas Adams wrote, is big.

Space may be really, really big, but it still pales in comparison to Chump's ego.

If I recall correctly, you put a baseball at 2nd base for a nucleus and the electrons are grain of sand buzzing around the outer bleachers for and atom. Simplified, of course. I think lately, the electrons are considered more of a fog out there.

Pretty much. They don't even talk about electron orbits anymore -- it occupies an orbital, which is a probability cloud of where the electron could be at any instant. But the old planetary model makes the idea of electron shells a bit easier to get a handle on.

Yeah, I remember little punch pins in the earliest science classes where electrons had orbits and quantum changes between orbits had the effects thought to be seen then.
