Activity 2 Post-Quiz

This activity covered the steps that should be taken to create an accurate scale model of the Solar System, a model that required walkers to be able to tour it in a few hours. Rank the following steps in the logical order.

1) decide what you what to create and make a plan for the model 2)calculate the scale factor for the relative sizes or distances to be used 3)apply the scale factor to the model 4)create the model

For our scale model of the Solar System, we used a diameter of 2,200 mm for the Sun to scale the sizes of all of the planets. Betelgeuse, the second brightest star in the constellation of Orion, is about 375 times as large as the Sun. Keep the distances of the planets the same and consider "what if." What if Betelgeuse replaced the Sun in our model? Its surface would extend out to just beyond which planet? (Planet distances from the model Sun are listed.)

Mars (361.9 m)

The star HD 10180 (star number 10180 in the Henry Draper catalog) has seven confirmed planets orbiting it. This table gives the mass of five of them (two have been omitted). In the interactive figure below, locate the first four planets listed in the table, given the four possibilities shown by the slanted lines.
