The first moons beyond Earth were discovered in 1610 by Galileo Galilei, who identified four of Jupiter's moons: Io, Europa, Ganymede, and Callisto. This discovery marked a significant milestone in astronomy, revealing that other celestial bodies could have their own natural satellites. Prior to this, Earth’s moon was the only known moon.

How is Pluto's relationship with its moon Charon unlike the relationships between other planets and their moons?

Technically, no, because our system is named for our star or sun, "Sol". Hence, Sol-ar or Solar system. The question becomes, "Is there another star system entering ours?". In general, the parts of the universe are all moving away from each other; however, there are a number of small galaxies that appear to be slowly (millions of years) moving toward our Milky Way galaxy. But, still 'No', there are no other star systems entering ours.
Does earth has a larger or smaller moon than other planets?
Our Moon is generally rated at the large end of the scale.Most planetary moons (such as those around Mars) are smaller than ours. To find any moons bigger than ours, you generally have to go to Jupiter or Saturn, where you will find the biggest moons in the system like Ganymede, Callisto, and Titan.
How does Charon's orbit around Pluto different from the orbits of most moons around their planets?
Charon orbits once every time Pluto rotates once. Other moons(including ours)don't do that.

Charon orbits once every time Pluto rotates once. Other moons(including ours)don't do that.
