This one is really driving home the scale of the solar system. Another amazing visualization of distances is the video "Powers of Ten" that goes to the largest and smallest distances. It was filmed in 1977 already but that only adds to its charme:

The scale is pretty accurate and all, but why is there giant text in space?

Relocated space trash from Earth‘s sattelites, neatly arranged.
Love the Female/Male symbols for Venus and Mars, nice touch
Um. Are those not the standard symbols?
They are indeed the standard symbols for those planets, and they do also coincide with the gender symbols, presumably because of the way the associations played out in classical mythology.

Fun extra fact: in Western alchemy, the symbols for major solar system objects ("planets", even though not all of them are planets by the modern astronomical definition) were also used to represent metals. Except HN seems to delete the symbols when I try to post them, so you'll have to look them up yourself, I guess!

I'd like to knock up a solar system in a right scale and I wondered how can I do that. Now that I see this article I think I just can't, not in a regular room at least. I guess I will not have my solar system in an accurate scale hung on my ceiling. Too bad
It's a fun thing for a walking/biking trail near you if you can get park permission though!
There is also the famous one starting in Stockholm: https://en.wikipedia.org/wiki/Sweden_Solar_System
There is another one in Hagen in Westfalen, Germany.

Allegedly the first. Sorry, didn't find any english link, but clicking on the 'Virtuelle Tour' there leads you to at least some maps where you can see how it is spread out through the city.

It helps that Pluto is no longer a planet but not much.

Uranus is 4.5 billion km from Sun and if, for the sake of simplicity, the model is 4.5m wide, that would mean that Earth with its diameter of ~13000km would be a speck just 0.013mm wide. That should be 1/10th of a single dot at a resolution of 200dpi if you are planning to print a map (one dot at 2000dpi but good luck printing that;). You might want to consider adding an arrow and a label.

You mean Neptune and Pluto's orbit is so eccentric that it is sometimes closer to the Sun than Neptune.
You can always look at the size dimension instead - you can relatively easily have the planets to scale next to each other (As long as you exclude the sun, of course).

Ever since I found out that the planets would fit neatly into the gap between the Earth and the Moon I've been toying with it as a tattoo idea

It's somewhat interesting that I was the happiest with Pluto being shown.
This website is a great example for me of useful, interesting, and original things that can be done on the Internet, instead of the abundant nonsense. Hope there was list of these websites.
I hope there was a search engine.
I don't know, the UI seems screwed up to me. They should have scrolled vertically, for one. It's more natural to people and mice design.
Glad to see this showing up every few years. After its initial launch, I think I helped the creator add the localization and lightspeed features: https://joshworth.com/updates-to-the-solar-system-map/

...and we eventually met up and had lunch.

I noticed the new light speed feature.. Shockingly slow compared to scrolling, really drives it home.
This is an amazing feature. It really shows how much we are stuck on our little blue pixels heap and how even getting to even Mars is an exploit.
I remember seeing this page back in the day and always thought it was really funny how it describes itself as being 'A tediously accurate scale model of the solar system' - you scroll over a bit and it points to "1 Pixel" for scale - but the "pixel" it points to is actually two pixels [0].

That could just be your client trying to handle a pixel-sized thing that isn't exactly aligned to your display's pixel grid.
This is one of the few tools that really gives a good sense of the relative scale of the solar system.
It's a good thing as we get more high res monitors the solar system is going to shrink. This would have been much much worse back on my Atari800xl

"Tedious" is right. Must have been designed for a phone, because on my desktop I gave up scrolling before I got to the first planet.
side scrolling is really fast with a trackpad
I clicked on the scroll bar to zoom through. Still pretty tedious, but I got the end.
You can hold down the right-arrow key to scroll, and you reach Mercury in 12 seconds.
Masterful copy, a feature many leave as an after thought but one of the slickest levers for user delight. Bravo 1 pixel moon man
I was just looking at this site earlier today independently of HN. I revisit it several times a year, mainly because I can’t get enough "scale of the universe" comparisons (if you know any good ones, please send them my way).

I especially love the light speed auto-scroll because it does a great job of visualizing just how slow the speed of light is (or how vast space is).

c is relatively slow

Only from our point of view. Photons have zero travel time from their perspective (thanks to Einstein). When you go with different speeds, approaching c, you see different distances (and things), and with just 1g acceleration, the same that pulls you down right now, you can go to the stars, galaxies and… well, just watch yourself:

My god, it's full of pithy remarks!
If you like to scroll vertically instead of horizontally, you might like this one that takes you to the bottom of the ocean:
