Remember building a solar system in high school? Cups and papier-mache balls are in the past, because Solar Walk is an interactive orrery that shows all planets and satellites of the solar system in their correct positions in real time.

This 3D solar system model lets you navigate between planets, see their positions on a specific date, explore how they move and why. You will see the entire Milky Way galaxy from a far and zoom in to study all the planets and satellites in close-up, learn their trajectories, inner structures, history of their exploration, and geography.

Every planet has extensive information: size, mass, orbital velocity, exploratory missions, thickness of structural layers, and composition of atmosphere.

“Can’t-miss app.” - Mashable

“Solar Walk serves up a visually impressive 3D model of our solar system. Set against a haunting, atmospheric soundscape, the app shows planets and satellites in their correct positions, and offers mini movies, facts and other related tidbits.” - TNW

“This jaw-dropping app provides a wholly interactive 3D model of our solar system, one that’s had me hooked for days. It’s the kind of thing you can imagine a science teacher using in the classroom of the future — except that we don’t have to wait.”

“Zoom from Mercury to Pluto (which makes the cut in this app), passing each planet’s moons along the way. Because Solar Walk knows what time it is, the planets are in proper orientation to the Sun: Earth is dark where it is currently night and gradually lightens to daytime on the other side.” - NY Times

Solar walk

This I would have to say is the best astronomy app ever! This app is highly detailed and well worth the money! This is very rich in color and detail in 3-D graphics beyond this world! Works well on an iPad Air 2. This app app I bet it would look extraordinary on in iPad Pro! Great job on the app! A must have for astronomers and anyone else interested in our solar system! Great for kids as well!

Great stuff
