A little perspective
Thebe vs One-hour drive at 100 km/h: length comparison
The distance of a one-hour drive at 100 km/h is about 1.01 times the mean-equivalent diameter of Thebe.
Thebe is a small, irregular inner moon of Jupiter that orbits close to the planet within its ring system.
A one-hour drive at a set speed is the distance a vehicle travels in one hour of uninterrupted motion.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions. A ruler represents the selected distance or a measurement not visible in this view.

Thebe
Mean-equivalent diameter: 98.6 km; approximate; range 90 km–110 km.
Jupiter moon Thebe is highly irregular, approximately 116 x 98 x 84 km. A 98.6 km mean-equivalent diameter is used for scale comparison; its mass is a model-dependent approximate value.
