- Using the “Scale of the Universe” applet, how much larger is the Sun than a human being? How much larger is the Solar System than the Sun and how much larger than a human being? Give the number in both Scientific form (exponent, or 10!”#$%!!”#) and words.
- Using the applet: in scale, what is to a human as a human is to the Sun? To an Astronomical Unit? To the entire Solar System?
3. Suppose you made a scale-model of the Solar System, with the Sun where I stand in the lecture hall, and every Giga- meter was represented by 1 foot. Where would Earth be (how many feet away)? Where would the last planet in our Solar System be? Where would the nearest star be?
