Both series are about tough futuristic jobs that sound awesome by today's standards but that your average person in the series wouldn't want to do because they are dangerous. They're both relaxing paced reads that showcase humanity's desire to be somewhere else they can see but cannot easily reach (the furthest stars in Planetes, the Earth in Saturn Apartments) and various characters reactions to said desires. They are also both "realistic" sci-fi series where things like gravity and basic science rules apply but things like giant robots and aliens are science fiction, giving their worlds a very similar vibe.
