In a drawing that represents a scale model of the solar system, the sun is placed at the center and the planets are shown orbiting in circles around it. While in reality Mars is 1.5 AU away from the sun, in the model Mars appears at 30 cm from it. Neptune is 30 AU away from the sun.

What is the maximum possible distance that can be drawn between Mars and Neptune in the scale model?



A. 28.5 cm

B. 570 cm

C. 630 cm

D. 1.5 cm



A human-operated spaceship reaches the moon in 3 days. The moon is about 386,400 km from Earth. Mars, our closest planetary neighbor, is, at its closest, about 140 times farther away from us than the moon if Mars stays in place. Assuming a very simple model of the solar system, about how long would it take that same spaceship to reach Mars?(1 point)

A. about 1 year

B. about 7.5 years

C. about 22.5 years

D. about 2.5 years

(1 point)

A. The planets are shown as having different shapes.

B. The planets are represented in different sizes.

Why do astronomers use astronomical units (AU) instead of kilometers (km)?(1 point)

A. Distances are more manageable in AU than in km.

B. AU is used in astronomy, while km is used in physics.

C. AU is used for spacing, while km is used for length.
