Jupiter: The gas giant. It is the largest planet, acts as a kind of "father figure" or authoritarian leader of the outer system, and holds a grudge for past events related to the formation of the solar system.

Saturn: Famous for its beautiful rings. It is relaxed, charismatic, and very protective of its system of moons, although its rings are sometimes a source of pride and vanity. It is forgetful about its moons and is Jupiter's best friend.

Venus: Characterized by being sarcastic, proud, and having a know-it-all attitude. It hides dark secrets beneath its thick atmosphere and extreme greenhouse effect. It always makes fun of Mercury.

A "react to" is where a group of people react to videos, which can be of musicals, soap operas, or of themselves. The videos can vary, covering topics like ships, angst, memes, tension, and more. These reactions usually take place in a room with couches and a TV in the middle of the room.
