Your investigation

  1. Draw one circle-like orbit and one very stretched oval. Put a pretend Sun near the center of the circle and off-center inside the oval.
  2. Draw arrows to show a traveler’s direction and label each line as a guide, not a physical rail.
  3. Write two limitations of your model, including that most planetary orbits are only mildly oval.
  4. Add a sentence about gravity bending a moving object’s path.

Think, draw, explain

Are real orbit lines glowing tracks in space?

Does an orbiting planet need a road beneath it?
