In Roman mythology, Pluto (Greek called Pluto) was the leader of the underworld. The planet got its name (but didn't take other suggestions) because it is too far away from the sun to be silent in endless darkness, or because the first two letters of Pluto are Percival Lowell, which is an abbreviation.

Hades is Zeus' brother. After defeating his father Klaus, he took charge of the underworld.

For hades. His Roman name is Pluto, the smallest and outermost of the nine planets. He is the ruler of hell and the dead, judging the dead and punishing them. His wife, Persephone, was robbed while he was traveling around the world. Hades is also the god in charge of wealth. He is in charge of gold and jewels buried in the ground.
