What is the diameter of the sun in the solar system?

• 1,400,000 kilometers

• 58,000,000 kilometers

• 9,000,000,000 kilometers

• 6,000,000 kilometers

How much wider is the solar system compared to the sun?

• 6,000 times

• 1,400 times

• 58 times

• 9 times

Why is it difficult to create a model of the solar system that shows both sizes and distances accurately?

• The solar system is too small.

• The objects are too close together.

• The sizes and distances are too vast to fit on a page or screen.

• The planets are all the same size.

What is the main advantage of using scale models of the solar system?

• They show the actual size of the sun.

• They allow comparison of size relationships.

• They are easier to draw.

• They show the color of planets.

Why are models that are not to scale still useful in understanding the solar system?

• They show the exact size of each planet.

• They help visualize size and distance relationships.

• They include only the inner planets.

• They are easier to build.

What is a limitation of the solar system model described in the text?

• It shows the exact size of the sun.

• It includes all the planets' orbits.

• It cannot show smaller objects in scale.

• It shows the inner planets clearly.

What is the main reason the orbits of Earth, Mercury, Venus, and Mars are not shown in the diagram?

• They are too far from the sun.

• They are too small to see compared to the whole solar system.

• They are not part of the solar system.

• They are not important for the model.
