1. Compare your estimated positions to the actual positions. Are there differences?
What surprises you most about the differences you see?
Yes, there are differences I
didn’t think they were that close together, but then they started spreading out further and
further apart
2. We often refer to the “inner planets” and “outer planets”. Describe the actual positions
of
the planets on your strip which illustrate this distinction. Where is the “split” between
inner and outer planets?
The "Inner planets" seem to be very clustered together near the sun,
and the asteroid belt splits the outer planets, which are very far away.
3. Some of the planets much further out than Earth are brighter in Earth’s night sky than
planets closer to Earth. What could that tell us about those brighter outer planets?
Those
planets reflect a lot more light toward us than the ones closer to us do
