A scientist visits the planetarium. The scientist views an exhibit on stars, which was made using lights and a computer program. How would this star exhibit be classified?

The star exhibit viewed by the scientist in the planetarium, which was made using lights and a computer program, would be classified as **a computer model**. This is because the exhibit utilizes computer-generated visuals to simulate the appearance of stars, rather than being a physical representation or a real-world instance of stars themselves.
