    Description:
    The user can either accelerate or slow the rates. This option is a strong exploratory tool. It is useful to explore “What if” questions, which helps understand how phenomena occur in the solar system.
    For example, the user can accelerate or slow the Earth rotation rate and deduce what would happen as a result.
    (Gazit, Yair & Chen, under review; Yair, Mintz & Litvak, 2001)
    The Rationale Behind the Feature (Specific Design Principle):
    The Virtual Solar System is a non-immersive 3D virtual environment. The user flies in the solar system by the computer mouse as a spaceship.

    The user can change the speed of the whole system by changing the rotation and revolution rates. The goal of this tool is to enable the user to view and explore phenomena deeply. The results of the change in rate can be seen immediately on the screen, and the user can deduce how the basic astronomical phenomena would change.
