Northern winter/southern summer is 154 sols, and northern summer/southern winter is 178 sols. Youll need enough space for each group to spread out and create their model, using the following scale, with each step equaling approximately 1 meter (about 3.28 feet): Emphasize that at this scale, the sun would be less than 1.3 centimeters (0.5 inches) in diameter. No planet in our Solar System orbits the sun in a perfect circle which means that the distance between planets is never the same. From deep below the soil at Earths polar regions to Plutos frozen heart, ice exists all over the solar systemand beyond. Then have students recreate the model. This would bring the two planets within 33.9 million miles (54.6 million kilometers) of each other but this has not yet happened in recorded history according to NASA (opens in new tab). The first person to ever calculate the distance to Mars was the astronomer Giovanni Cassini, famous for his observations of Saturn. Use the provided answer key to check groups work.
