Scale Models of the Solar System

This video tutorial introduces the concept of scale models in astronomy, focusing on the solar system. It explains how to calculate scale factors and apply them to create models of planetary distances and sizes, specifically using the Earth-Moon system as an example. The tutorial also provides instructions for an assignment where students will calculate scale models of the solar system, emphasizing the importance of accurate calculations and conversions.

What is the main challenge in creating a scale model of the solar system?

• Deciding the order of planets

• Finding accurate data for planet sizes

• Choosing the right materials for the model

• Balancing the sizes and distances accurately

How is the scale factor calculated in the Earth-Moon system example?

• By dividing the scaled diameter by the actual diameter

• By subtracting the actual diameter from the scaled diameter

• By multiplying the scaled diameter by the actual diameter

• By adding the scaled and actual diameters

What is the scale factor used for in the Earth-Moon model?

• To determine the color of the moon

• To measure the temperature of the moon

• To find the mass of the moon

• To calculate the distance between Earth and the moon

In the assignment, what unit is the given diameter of the Sun provided in?

• Meters

• Inches

• Kilometers

• Centimeters

What should you do if your calculated scale factor results in a very large or very small number?

• Ignore it and proceed

• Recheck your calculations

• Use a different scale factor

• Convert it to another unit
