* Distance: Jupiter is much farther from the Sun than Earth is. At its closest point, Jupiter is about 484 million miles from the Sun, while Earth is only 93 million miles away.
* Perspective: From this great distance, the Sun would appear much smaller in the sky. While it would still be the brightest object, it would lose its apparent size and disc shape.
* Brightness: Even though it appears smaller, the Sun would still be incredibly bright. It would be the most prominent object in the Jupiterian sky.
So, while the Sun would be a bright star from Jupiter, it wouldn't be the giant, blazing disk we see from Earth. It would be a point of intense light, much like any other star in our night sky.
