AA - Solar System is Huge

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

• 1,000 times

• 6,000 times

• 10,000 times

• 100 times

What separates the Sun from Mercury?

• 1.4 million km of empty space

• 9 billion km of empty space

• 58 million km of empty space

• 100 million km of empty space

What do scientists use to address the difficulty of modeling the solar system?

• Only scale models

• Only non-scale models

• Both scale and non-scale models

• Computer simulations only

What is the purpose of scale models?

• To show the exact size of objects

• To compare size relationships

• To display colors of planets

• To measure temperature

What is a characteristic of non-scale models?

• They show exact distances

• They are not useful

• Sizes may not be changed by the same percentage

• They are always accurate

What is the main focus of the document?

• The history of the solar system

• The size and scale of the solar system

• The temperature of planets

• The color of stars

This image shows the size of the sun compared to the size of Earth.

• The sun is about 109 times the diameter of Earth.

• The sun is about 10 times the diameter of Earth.

• The sun is about 50 times the diameter of Earth.

• The sun is about 5 times the diameter of Earth.

Why can't the model show the orbits of the inner planets like Earth?

• They are too large.

• They are too small.

• They are too far from the sun.

• They are not part of the solar system.

What is the purpose of models that are not to scale?

• To show the exact size of planets.

• To show size and distance relationships.

• To show the color of planets.

• To show the temperature of planets.

What does the model to the lower right fail to show accurately?

• The color of the planets.

• The relative sizes of the planets and their distances.

• The temperature of the planets.

• The number of moons each planet has.
