The correct statement describing the way the planet sizes are shown compared to their orbits in the video is: The planets are all much too large compared to their orbits. This is because, while the planetary orbits are shown to scale, the actual sizes of the planets are so small relative to the vast distances of their orbits that if they were shown to scale, the planets would be almost invisible. For example, Jupiter, the largest planet, has a diameter of about 86,881 miles, but its orbit radius is about 484 million miles. Thus, to show both orbits and planet sizes to scale in the same model is impractical, and the planets are depicted much larger than they would be if truly to scale with their orbits
