    A LITTLE PERSPECTIVE

    A universe you can explore.

    Drag to pan. Right-drag, Shift-drag, or switch on Rotate to change your angle. Scroll or pinch to zoom toward your pointer; time pauses automatically. Double-click or double-tap a world to glide closer. Home smoothly restores the overview. Press Space to pause or resume, or use + / − and arrow keys when the scene is focused.

    Orbits use Kepler’s equation, approximate eccentricities, inclinations, and real relative orbital periods. Initial positions are illustrative, not a live ephemeris. Distances and planet sizes are compressed independently.

    Axial tilts and rotation directions are represented. Spin and orbit share one clock. Focused views slow both by 240× (1 Earth day per 24 seconds at the default speed). Overview uses the faster rate shown in the controls.
