Föderation EN Do 27.02.2025 03:46:23 @wonderofscience this video even scales rotational velocity, that is nice! |

Föderation EN Do 27.02.2025 04:30:47 @wonderofscience I've seen things like this before, but showing the comparative rotation rates was a nice touch. In order to be able to see Venus, Mercury, and the Moon rotating, the others would have to be a blur. Also, Venus would be going in the opposite direction to most of the others. |

Föderation EN Do 27.02.2025 07:50:52 @StarkRG ah, that makes sense. I thought maybe parts of the image were tidally locked ;) @wonderofscience |

Föderation EN Do 27.02.2025 08:41:30 @xinit @wonderofscience I'm pretty sure I can see the Moon rotate a teensy bit, but the others are probably static images. The Moon should make a full rotation for every 28ish rotations of Earth, but Mercury would take over twice as long, almost 59 Earth days, while Venus would take 243 Earth days, which is slightly longer than its year. Also, as I said, it's backwards (or upside-down, since the definitions of North and South are usually based on the direction of rotation). Venus is an odd goat. |

Föderation EN Do 27.02.2025 07:24:51 Love this. Really great. Also, the solar system is really big, and planets are relatively really small. If the solar system where the size of a football stadium, the Sun would be the size of a pea, and the earth the size of a speck of dust. |

Föderation EN Do 27.02.2025 09:50:33 @wonderofscience Uranus and Neptune are so close in size. And Saturn isn't that much smaller than Jupiter. |

Föderation EN Do 27.02.2025 10:44:19 @wonderofscience I was fortunate enough to have lived in Boston, around year 2000, when there was a solar system scale model. We cannot really picture how tiny the planets are in the vastness of space. In that model, Sun at the center had a diameter of 3.5 meters. Earth would be about the size of a soccer ball, 400 meters from the sun. You'd have to drive 15km to see Pluto, which was about the size of a baseball. |

Föderation EN Do 27.02.2025 11:27:56 @Supertapani @wonderofscience The University of Oslo used to have an Astro Festival each year. The campus is fairly long with a walkway in the middle, and they always had a line-up of planets to scale and with the correct distance, starting with the Sun at the physics building. |

Föderation EN Do 27.02.2025 11:27:40 @wonderofscience this made me curious so I checked: turns out Marsβ surface area is only 3% less than the total land area of Earth not that any of that will ever make usable farmland but itβs interesting to put into relation |
