Solar System Distances Quick Check

Question
Use this paragraph: In a scale model of the solar system, the sun is placed at the center and the planets are shown orbiting in circles around it. Mars is 1.5 AU away from the sun and in the model, it appears at 30 cm from it which means that 1 AU = 20 cm. Likewise, 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? Hint: Two planets are as far apart as possible when they are on directly opposite sides of the sun from each other. Draw a picture with the planets as far apart as possible.

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)

about 7.5 years

about 1 year

about 2.5 years

about 22.5 years

What is the main problem with this model if it were going to be used to study the dimensions of the solar system?

(1 point)

The planets are depicted in different colors.

The planets are placed at the same distance from each other.

The planets are represented in different sizes.

The planets are shown as having different shapes.

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

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

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

Large distances are easier to express in AU than in km.

There are no km in outer space, only AU.
pls help me I'll fail
