What is the diameter or total distance of Jupiter
Answer
How long does it take light to travel the entire planet
Answered by GPT-4o mini
The diameter of Earth is approximately 12,742 kilometers (7,918 miles).

Jupiter, on the other hand, is the largest planet in our solar system and has a diameter of about 139,820 kilometers (86,881 miles).

If you are referring to the circumference (the total distance around the planet) rather than the diameter, the Earth's circumference is about 40,075 kilometers (24,901 miles) at the equator, while Jupiter's circumference is approximately 439,822 kilometers (273,709 miles) at the equator.

To calculate the time it takes for light to travel around Earth or Jupiter, we can use the speed of light, which is approximately 299,792 kilometers per second (about 186,282 miles per second).

### For Earth

1. **Circumference of Earth**: ~40,075 kilometers.
2. **Time taken for light to travel around Earth**:
\[
\text{Time} = \frac{\text{Circumference}}{\text{Speed of Light}} = \frac{40,075 \text{ km}}{299,792 \text{ km/s}} \approx 0.1337 \text{ seconds} \text{ (or about 133.7 milliseconds)}
\]

### For Jupiter

1. **Circumference of Jupiter**: ~439,822 kilometers.
2. **Time taken for light to travel around Jupiter**:
\[
\text{Time} = \frac{439,822 \text{ km}}{299,792 \text{ km/s}} \approx 1.466 \text{ seconds}
\]

So, light takes approximately **0.134 seconds** to travel around Earth and **1.47 seconds** to travel around Jupiter.
