Scale of Solar System

Mr. Wilson tells the class that scientists are going to send a rover from the Earth to Mars. Describe how far the rover would travel based on the class model.

• 0.5 AU which would be 1.25 yards

• 1 AU which would be 1.25 yards

• 0.5 AU which would be 1 yard

• 20 AU which would be 1 yard

Describe how the distances between the orbits of the inner planets compare to the distances between the orbits of the outer planets.

• The distances between orbits of the outer planets are much smaller.

• The distances between orbits of the outer planets are much larger.

• The distances between orbits of the inner planets are much larger.

• There is no difference between the distances of the orbits of the inner planets and the outer planets.

Our solar system is made up of the Sun, 8 planets, and other bodies such as asteroids orbiting the Sun. The solar system is very large compared to anything we see on Earth. The distance between planets is measured in astronomical units (AU). One AU is equal to 149.6 million kilometers, the average distance between the Sun and Earth. Scale models are useful for helping us understand the size of the solar system. Mr. Wilson’s science class made a scale model of the solar system. They went out to the school’s football field, and they used the chart shown below to mark out the scale distance from the Sun to each planet. Choose the most correct answer about what the model of the solar system on the football field shows.

• the model shows the distances of the planets compared to each other

• the model shows the size of the planets compared to each other

• the model shows the composition of the planets compared to each other

• the model shows none of the above

According to the data, which planet has the greatest mass?

• Venus

• Saturn

• Jupiter

• Earth

The sun looks small in the sky because...

• It is small compared to Earth

• It is really far away

• It is not very bright

• The moon redirects the light

Why do scientists use scale models to study the Solar System?

• The solar system is too large to study without using models

• The solar system is too small to study without using models

• Scientists don't need to use models because we have satellites

• All of these options are true

What is the primary reason for using a logarithmic scale when representing the distances in the Solar System?

• To make the distances appear more uniform

• To accurately represent the vast differences in distances

• To simplify calculations

• To make the planets appear larger
