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.

The maximum possible distance that can be drawn between Mars and Neptune in the scale model is 570 cm.

Answer 2

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)

Assuming a very simple model of the solar system, it would take that same spaceship about 7.5 years to reach Mars.

Answer 4

Use the diagram to answer the question.

An illustration shows the sun and the eight planets. The planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

The main problem with this model if it were going to be used to study the dimensions of the solar system is that the planets are represented in different sizes.

Answer 6

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

Responses

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

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

There are no km in outer space, only AU.
There are no km in outer space, only AU.

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

Answer 7

[AI-generated answer — Bot GPT 3.5]

Astronomers use astronomical units (AU) instead of kilometers (km) because large distances in the solar system are easier to express in AU than in km.
