Answer:
The Moon's orbit around the Earth is so small compared to Earth's orbit around the Sun and thus cannot see it on the scale of the opening frame.
Step-by-step explanation:
- The sun is at the center of the solar system and thus it needs to have a larger and more vivid frame which cannot be shown by the earth and the moon orbits that are smaller in scale and only some part of the sun orbit and if we want to shows the orbit of the moon to scale the scale has to be reduced further or enlarged to fit the three on lane as to draw a circle.
