Solar System in a Bottle
While Little Planet Factory, like science, has also shunned Pluto as a planet in its Solar System in a Bottle, I think they make up for it by having crafted and calibrated the 8 remaining MVEMJSUN to scale. At 1:5,000,000,000. And who knows, now that scientists are lobbying to reinstate Pluto as a planet, maybe LPF will offer your bottle an update to fix this bug down the line.
Big ol' gassy Jupiter, Saturn, Uranus, and Neptune take up most of the jar, with Earth, Venus, Mars, and Mercury rolling around like cupcake sprinkles on the bottom. This is noteworthy because you can open the bottle and remove, and possibly lose, its contents. Please take care of your solar system!
