Orbit Viewer


Orbit Viewer is an interactive display of spacecraft orbits and realtime locations. Data is used from the JPL Horizons system.

This is built as a WebGL experiment using Three.js and is expected to work in the latest versions of Google Chrome, Firefox, & Internet Explorer 11.

  • Click 'Start' to begin the animation, then control with 'Pause' and 'Resume'.
  • To move to a specific date, set the 'Start Date', then click 'Reset to Start Date'.
  • Adjust the animation speed using 'Animation Speed'.
  • Use 'Targeted Planet' to change which planet is being watched. Note that the asteroid list is optimized for Earth resulting in possibly incomplete lists for other planets.
View Controls: Orbit Viewer uses mouse and keyboard based navigation controls, similar to those in Google Earth.
  • Rotating: Rotate the scene by left-clicking and dragging with the mouse
  • Pitch/Roll: Control the pitch & roll of the scene by holding down shift while left-clicking and dragging with the mouse.
  • Panning: Pan the scene (offsetting the planet from the center, similar to turning your head away from the object of focus) by holding down Ctrl while left-clicking and dragging with the mouse.
  • Zooming: Zoom either with the scroll-wheel or by right-clicking and dragging the mouse up or down.
