Compare Object Distances Practice Test

A scale model uses average center-to-center distances. The model sets Earth–Sun (149,600,000 km) to be 1.0 m. (This model is intended to be to scale.) About how far from the Sun should Jupiter be on the model if Jupiter–Sun is 778,500,000 km?

Choose the closest value.

Use the table of average center-to-center distances (km). (These are averages; real distances change. Diagrams may not be to scale unless stated.) Which distance is much larger than the others?

• Earth–Moon: 384,400 km
• Earth–Sun: 149,600,000 km
• Mars–Sun: 227,900,000 km
• Jupiter–Sun: 778,500,000 km
