You can start with Eyes on the Earth to explore Earth’s life signs (carbon monoxide levels, temperature, etc) or to watch our many satellites traveling around us. Move on to Eyes on the Solar System to see any part of our solar system from any vantage point. Finally, move way out across the universe with Eyes on Exoplanets.
Everything is accurate for both scale and time. Satellites and planets move at their actual speed (you can speed them way up if you like, but then everything else is speeded up by the same amount). No matter where you look, you’ll see a real time visualization with everything in the correct position and of the right size relative to your vantage point. You can move forward or backward in time to see how things looked at precise moments in history.
