CloudLabs Planetary system vs Terra

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.

Terra shows facts about our planet the way they really are: on an interactive 3D globe, at true proportions, with real data behind every number. Put any scene in your room with AR at a scale you choose. SIZE & SHAPE - True Size: drag Greenland onto Africa and see how far the Mercator map misleads - Bigger Than You Think: Africa outsizes the USA, China, India and Europe (without Russia) put together; your country next to others its size - How round is Earth, really — the spheroid and the relief, exaggerated or not - Shortest routes, the horizon from any height and how much the curve hides, moving tectonic plates and the Ring of Fire - Through the Earth: your antipode, and a straight tunnel from London to Sydney through the planet's layers WATER - All of Earth's water gathered into one sphere — and the fresh water, and the lakes and rivers - Ice sheets as slabs over the land - Sea level: raise the ocean and watch real coastlines flood — or lower it to the last ice age, when Britain was joined to Europe - How many days all the world's rivers would take to fill Lake Baikal - Fourteen lakes, each with a ball of its true volume — and the world's rivers and yearly rainfall on the globe PEOPLE - Population as columns on the globe - Half of humanity lives inside a surprisingly small circle - If everyone lived like Manhattan, Paris or Houston - Earth at night: city lights from space - Your share of the planet: your square of land and cube of water, at true size in AR TIME & SEASONS - Live Earth with the real day/night line and the Moon's phase - Why seasons happen: the orbit, the tilt, and the same sunlight spread over more ground - Day length at every latitude, and why noon isn't at 12:00 - Time zones and how far they are from the Sun Every figure is traceable: tap ⓘ in any scene for its sources (NASA, NOAA, USGS, UN, Natural Earth and others). Four scenes are free, one per chapter. A single one-time purchase opens the other eighteen and AR in every scene. No subscription, no ads, no account, no tracking — the only thing that goes online is the purchase. In 14 languages. Metric or imperial units. iPhone, iPhone Duo and iPad.
