* Distance: Jupiter is about 5.2 astronomical units (AU) away from the Sun, while Earth is only 1 AU away. This means Jupiter is over 5 times farther from the Sun than Earth.
* Inverse Square Law: The intensity of light decreases with the square of the distance. Since Jupiter is over 5 times farther, the Sun's light reaching Jupiter is about 25 times dimmer.
How bright is the Sun on Jupiter?
* The apparent magnitude of the Sun from Jupiter is about -26.7. This is much dimmer than the Sun's apparent magnitude of -26.8 from Earth.
* While the Sun would still be the brightest object in the Jupiter sky, it would appear about 25 times dimmer than it does from Earth.
To put it into perspective:
* Imagine the Sun as a light bulb. From Earth, it's a powerful, bright bulb. From Jupiter, it's like a dimmer, less powerful bulb.
Important Note: Even though the Sun appears dimmer from Jupiter, it still provides enough light and heat to support Jupiter's massive atmosphere and its many moons.
