Code Number: 8A20.65
Demo Title: Earth/Moon/Sun Demo - Tellurium
Condition: Excellent
Principle: Planetary Motion, Small Angle
Area of Study: Solar
Equipment:
Earth/Moon/Sun demo Unit.
Procedure:
No advanced preparation is necessary. Unit should be clamped to table or bench when used to prevent breakage. Everything on this model is accurate as far as the rotation rates and angle of the planet is concerned. The only thing not right is that the moon is fixed in an equatorial path instead of having the proper 5 to 7 degree tilt.
