The sun does not belong in the group of planet, galaxy, and moon. While planets and moons are celestial bodies that orbit around stars, a galaxy is a vast system containing stars, planets, and other celestial objects. The sun is a star and is fundamentally different from the others listed, which are not stars.
"Galaxy", because all the others are in our Solar System. What about "exoplanets" outside our Solar System? Well, I don't think the question is meant to be that complicated.
The third planet from the sun is the earth. Our entire solar system, including the earth, is in the Milky Way Galaxy.
The sun does not orbit around the moon. The earth orbits the sun and the earths moon (every planet has 1 or more moons) orbits earth.
They have to orbit the sun or orbit a planet. This means they are if they are in the Galaxy.
Starting from least to greatest magnitude in size: Earth Sun Solar System Milky Way Galaxy Universe
Item: galaxy. The other items are celestial bodies within a galaxy, while a galaxy is a collection of stars, dust, and gas held together by gravity.

The Sun belongs to the Milky Way galaxy.
Laser, all the others are bodies/things in space.
A planet orbits a star such as the sun. A moon orbits a planet.
A moon, by definition, is not a planet. The closest planet to our sun is Mercury, followed by Venus and the Earth, then Mars.
No. Mercury is the closest planet to the sun. The moon is not a planet and is the closest object in space to Earth.
No. The sun is a star, not a planet. The moon is a moon. If it had its own orbit around the sun it would be considered a terrestrial planet.
No. A moon orbits around a planet. A planet orbits around the sun.
