CloudLabs Planetary system vs Scale of U

In this simulation, you are asked to calculate some measurements of celestial bodies, such as area, perimeter, and volume. To do so, a holographic projector is available for the observation and measurement of the necessary distances. The correct calculation of these properties will help the astronauts learn more about the new planetary system.

Scale of U draws everything at its true relative size, from a proton to the observable universe. Pinch to zoom and travel across 42 powers of ten: atoms and molecules, insects, people and animals, everyday objects, moons and planets, stars and galaxies. What you can do • Explore 161 objects in 3D, from the proton and the hydrogen atom to the Milky Way and the observable universe • Zoom smoothly from 10⁻¹⁵ to 10²⁷ meters with a pinch, the slider, the scale buttons or a keyboard • Tap any object to center it, turn it in 3D and read what its size measures • Compare two objects side by side at one shared scale, such as Earth and the Moon or a honeybee and a grain of sand • Walk through ten categories in size order: everyday objects, the solar system, worlds, moons, exoplanets, stars, galaxies, insects, molecules and elements • Take a guided tour from tiny to vast, at your own pace • See NASA surface maps and Hubble photographs, each with its credit Made for classrooms and curious people • Free, with no ads, no accounts and no data collection • Designed for iPad and iPhone, in landscape or portrait, and in Split View • 3D models download as you explore and in the background on Wi-Fi, so the app works offline once they are stored. Until then, every object shows a picture. Honest about sizes Every object says what its number measures: a diameter, a length, a wingspan or an orbit. Sources are listed for each one. Models are schematic where no photograph exists. Scale of U is also on the web at scaleofu.com. Made by Grossard Education.
