That might not help without the size of the astronomy building, the size of the models, or how long the walk was to the nearest star. Here are some approximate dimensions. In Miami the sun would be 9in or 22cm[1], the inner solar system could be depicted on a line 120ft or 35m[2] long, and Pluto would be about 1000yds or 1km[3] away. Divide by two if the university is in San Francisco, which is about 2000 miles away from Anchorage rather than 4000. Or divide by ten if the university is in Alaska and the nearest star's model is only 400 miles away.
