To label the model of Earth in its orbit around the Sun with respect to the different seasons in the Northern and Southern Hemispheres, you can use the following labels for the drop targets:
- Drop target 1: Northern Hemisphere (showing winter)
- Drop target 2: Southern Hemisphere (showing summer)
- Drop target 3: Sun
- Drop target 4: Equator
- Drop target 5: Axis of rotation
Make sure to adjust the labels according to the specific model you are looking at, as the positions might vary slightly based on the representation of Earth's orbit and tilt.
