  • That's the terminator.

  • The terminator, also called solar terminator or thetwilight zonemoves around our planet once a day.

  • That axial tilt causes one pole to be facing the Sun, and the other pole facing away, and that gives our planet its four seasons.

  • The terminator is a guide for solar-powered low earth orbit satellites.

  • They ride the line in total sunlight to take pictures of Earth.So while the terminator

  • doesn't really do anything, it is good for science!
