its a planet. not a moon.
Jupiter's largest moon, Ganymede, is as big as the planet Mercury.
A small planet going round a big planet is called a moon. Like our moon, it is smaller than Earth - so all planets orbiting round a bigger planet is called a moon.
Yes. The moon is about as big as the united states of America. Minus Alaska and Hawaii.
The moon, our moon, is sometimes called the 'Big Cheese'. Its not made of cheese though.

Right from moon? It appears as if a moon but big in size.
There is no such planet known. In our solar system, the planet whose moon is closest in size to the planet which it orbits is none other than our own planet Earth. However, the Moon is still much smaller than the Earth. Pluto has a Moon that's big, but Pluto isn't a "planet" now, of course.

Moons do not have to be any size but if the moon is bigger than the planet that it orbits, then the moon becomes the planet because it has more gravitational force.
The moon is always a sphere. The shape of the moon that we see - is governed by its orbit around our planet.
Before life existed on Earth a Mars like object collided with our planet. A big chunk of the Earth floated away from our planet due to the pressure of the collision. And that big chunk is now what we call, the Moon.
