Because you are closer to it as it is a moon of Jupiter.
In this painting commissioned by Federico Gonzaga of Mantua, Jupiter appears to Io in the disguise of a cloud. This allows Jupiter to conceal his true identity and approach Io without her realizing who he truly is.
IO is the fifth moon of Jupiter in terms of distance from Jupitert and the primary of the Galilean moons.
Io is a moon of Jupiter. It can have a period of revolution around Jupiter of 1.769 days or you can have Jupiters revolution around the Sun of 11.85920 days.
Ganymede and Io are both moons of Jupiter.
Io is a satellite of Jupiter.
Io is the brightest moon of Jupiter because it is the most geologically active, with frequent volcanic activity that produces sulfur compounds on its surface. These compounds reflect more sunlight, making Io appear brighter than other moons.
Io is 400,000 km from Jupiter, while it is 600 million km from Earth. Therefore it is 1500 times closer to Jupiter, and because of that would appear 16 magnitudes brighter. It appears as a 5th magnutide star from the Earth, so its magnitude from Jupiter would be -11, which is about half as bright as we see our moon.
The moon Io would look the brightest from the surface of Jupiter because It is the nearest.
Europa would appear the brightest from the surface of Jupiter due to its icy surface reflecting a significant amount of sunlight. Io may also appear bright due to its high volcanic activity, but Europa's icy surface would likely reflect more light overall.

IO
Jupiter and Io are connected because Io is one of Jupiter's moons. Io is the innermost of the four Galilean moons and is known for its active volcanism and unique surface features created by its interactions with Jupiter's intense magnetic field.
Jupiter has the Moon called Io - the most volcanically active object in our solar system.
That would be Io.
IO is the fifth moon of Jupiter in terms of distance from Jupitert and the primary of the Galilean moons.
Io's energy source is external---Jupiter's gravity. Io orbits very close to Jupiter, the planet's huge gravitational field produces strong tidal forces on the moon, resulting in a large tidal bulge. If Io were Jupiter's only satellite, it would have long ago have come into a state of synchronous rotation with the planet. In that case, Io would move in a perfectly circular orbit with one face permanently turned toward Jupiter. The tidal bulge would be stationary, and there would be no internal stresses and no volcanism. However, Io experiences tidal pull from Jupiter's other moons also.
IO is a moon of Jupiter. Jupiter is the 5th planet from the Sun.
