Because the moon is much closer to us. Jupiter is more than a thousand times farther away than the moon.
Larger
Because you are closer to it as it is a moon of Jupiter.

Ganymede would appear to be the brightest moon from the surface of Jupiter. This is because Ganymede is the largest moon in the solar system and it has a high albedo, meaning it reflects a lot of sunlight. Its larger size and reflective surface would make it appear brighter than the other moons when viewed from Jupiter.

The moon may appear big in the night sky due to an optical illusion called the "moon illusion." This occurs when the moon is near the horizon, where objects in the foreground, like buildings or trees, create a frame of reference that makes the moon appear larger in comparison.
The moon appears larger at times due to an optical illusion called the "moon illusion." This occurs when the moon is closer to the horizon, making it appear larger compared to when it is higher in the sky.
The two Jovian planet satellites that are larger in size than mercury are Ganymede and Titan. Ganymede is the moon of Jupiter and Titan is the moon of Saturn.
Jupiter's largest moon is Ganymede, with a radius of 2640 km.
The planet Mercury with a diameter of 3030 miles (4878 kilometers) is smaller than Jupiter's moon Ganymede (5276 km) as well as Saturn's moon Titan (5150 km). Jupiter's moon Callisto (4800 km) as also nearly the same size as Mercury.
The moon may have appeared bigger than usual due to the "supermoon" phenomenon, where the moon is at its closest point to Earth in its orbit, known as perigee. This can make the moon appear larger and brighter in the sky.
Yes, Jupiter is currently the brightest thing in the night sky, not counting the moon.
