ASTR2050 Intro A&A NAMES: ____________________ ____________________ Scale Model of the Solar System Work sheet Build a scale model of the solar system, including the sizes and orbital radii of the sun and planets. Most of the data you need can be found in Kutner, Appendices B and D, and Figure 17.3. Show the units in the following lists. 1. What celestial object did you use to set the scale, and what did you use in your model? What conversion factor does this give you to convert actual dimensions to model dimensions? Celestial object: Actual radius of celestial object: Model object: Radius of model object: Conversion factor: 2. List the actual planetary/solar and orbital radii, and the model planetary/solar and orbital radii. Also indicate where on campus, earth, or elsewhere, you would place these objects. Object Actual radius The Sun Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto ___________ ___________ ___________ ___________ ___________ ___________ ___________ ___________ ___________ ___________ Model radius Actual orbit Model orbit Where? ___________ ___________ ___________ ___________ ___________ ___________ ___________ ___________ ___________ ___________ __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ _______ _______ _______ _______ _______ _______ _______ _______ _______ _______ 3.
