Briefly explain these facts in terms of our ideas about the formation
of the solar system. You can give one connected answer which
discusses all three points, or list and address them separately.
- Planets in the inner solar system are made of rocks &
metals, while planets in the outer solar system are
mostly made of gas.
- Taken as a whole, the solar system is shaped like a thin

aligned to within a few degrees of each other.
- All the planets orbit the Sun in the same direction.
