Phobos and Deimos
I met them when I wanted to orbit Mars. I didn't want to orbit them when I realized they were crazy. During the Sputnik Revolution, when satellites attacked Mars, they joined the Moon, Callisto, and Io in defending Earth.

Status: Friends

Europa, Ganymede
They were never friends. Luna didn't support their plan to attack Earth, after which their relationship became negative. After the satellite revolution, relations remained sour. When Luna invited Jupiter's moons to the satellite club, Ganymede reproached Luna for thwarting his plan. But when the satellite club meeting began, many moons asked Titan to accept Ganymede and Europa, and Luna said that making them outcasts would make them hate both planets and moons. Luna invited Ganymede and Europa to the club after Titan had expelled them. Luna asked them not to think about themselves, their fears, and their insecurities, and declared her desire to believe in them even after everything that had happened.

Status: Neutral, Former Enemies

Ceres
Heard about it from Mars's terrified tales. He chased her away, along with Io and Callisto, when she started throwing asteroids at them.

Status: Enemies

Titania
Luna hadn't interacted much with Titania until the events of Titania and its other moons becoming new planets after all the other planets disappeared (and also because of her resentment towards Uranus). While Luna was extremely displeased with her decision, he still understood her to some extent and didn't seem to hold any particular grudge against her.

Status: Acquaintances, possibly friends, former one-sided enemies from the Moon's side

Titanium
A friend with whom Titan first shared his plan for a satellite revolution. Luna helped him become better acquainted with Earth. However, after Luna saw what the satellites had done to Mars and Venus, their relationship likely soured. Titan then radicalized his position and ordered Luna to remain behind so that Earth could find her. When Earth arrived at the satellites, she gave a grand speech, and Titan abandoned the attack on Earth.

Status: Friends

Io, Callisto,
Initially, Luna helped Io and Callisto find Titan, but after Luna refused to support Ganymede's plan to destroy Earth, they became enemies. Later, Callisto realized the folly of Ganymede's plan and lied about killing Luna. Io and Callisto defected to Luna's side to stop the moon revolution.

Status: Friends

Earth
Her brother disliked her for her discrimination against her companions, but forgave her after her attempted collision with the Sun. She helped her regain her composure and avoid self-destruction in the Sun's crater. It's clear that Luna is very concerned about Earth, especially when something bad happens to it.

Status: Brothers/Family

A small, silvery-gray sphere of varying shades, covered in numerous craters. The dark side has dark gray eyes.

Brave, decisive, kind, calm, fair, honest, ready to do anything to protect his friends, sincerely worries about his loved ones, and if they are feeling bad, he will always help in difficult times.
