The beautiful ‘mandala paths’ traced by Mars, Mercury and Venus – using the Tychosium’s trace function

The Tychosium is the only existing interactive simulator that conforms to all empiric astronomical observations of our solar system’s bodies in relation to themselves – AND in relation to the stars. It is a joint effort by Simon Shack and Patrik Holmqvist, based on (their revised version of) Tycho Brahe’s geoheliocentric model.

The Tychosium 3D program is a work in continuous progress and presently includes:

  • adjustable system speed control
  • full spatial 3D toggling control
  • ability to set the date & time of day
  • orbital tracing function for each planetary orbit
  • most of our solar system’s main bodies (minus Uranus, Neptune and Pluto)
  • Earth cam viewing option (experimental)

It is important to realize that the Tychosium is the first ever animated planetarium to correctly simulate our planetary (and lunar) motions – by means of uniformly circular (or trochoidal) orbits and constant orbital speeds. This was, of course, the ideal (“preferred by nature”) pursued by our world’s astronomers throughout the centuries. That is, before Kepler came along and computed his own, peculiar “laws of nature”! Most significantly perhaps, the TYCHOS’ geometric configuration does away with (i.e. fully resolves*) the macroscopic aberrations of perspective that afflict the currently adopted Copernican – Keplerian geometry of our solar system (*as thoroughly expounded and illustrated in the TYCHOS book).
