Scaling Planetary Distances and Sizes

The video tutorial explains a project where students scale down the sizes and distances of planets to create a model. It begins with an introduction to the project, followed by a detailed explanation of how to scale down the size of Mercury using a specific scale. The tutorial then covers how to calculate the radius and emphasizes the importance of precision in measurements. The same scaling method is applied to Venus and other planets. Finally, the video demonstrates how to calculate the scale distances between planets and the Sun, using Mercury and Venus as examples.

• To measure the actual size of planets

• To scale down the size and distance of planets

• To increase the size of planets
