Scale Model of the Solar System
... Solar System Scale Model The scale model will show the distance from the Sun to each planet. It will show the planets lined up in order. Please note that the planets are not actually lined up this way, but it is a convenient model to illustrate the planets’ comparative distances. 1. Turn this paper ...

... (c) Much higher. First, there’s a greater surface area from which particles can come off. Most importantly, however, is the fact that the gravity at the surface of the star is much less (see (b) above). This means that the particles aren’t bound as tightly. They are also moving slower (because the ...
