Which planet do have 27 moons?

Answer 1

The larger planets have much greater gravity than the inner planets, and large and complex moon systems have developed. Uranus has 5 large moons in regular orbits and 13 smaller ones closer to the planet, some involved with the tenuous rings around the planet. The 9 known outer moons are thought to be captured asteroids. They circle at from 5 to 20 million kilometers from the planet and all but one have retrograde orbits (the reverse direction from the larger moons and from the planet's rotation).
