Solar Walk 2 has all-new graphics and concept. New “crispy” visuals bring to life atmospheres of all planets. We have added the Calendar that includes hundreds of past and future space events of history of space exploration, natural celestial events, anniversaries, discoveries, etc. Also you will be able to see simulated trajectories and positions of all events from the Calendar. All background stars can be selected and have brief info. Information for planets and natural celestial objects has been revised to include great comparative infographics. These are major differences but there are so many more to explore.
