The human main protagonist. Ever since he was a kid he dreamed of going to space. When he finally got to accomplish that dream, he learns that the planets can talk, and it freaks him out.—-
- Got Volunteered: He's often forced to do missions that he otherwise wouldn't do, such as survive on the surface of Venus, terraform Mars, or find life on Titan.
- Only Known by Their Nickname: His name was never revealed. He was nicknamed "Dude" during the tests, and later "Astrodude" by the Solar System.
- Token Human: He's explicitly stated to be human and while there are other people, he's the only major recurring human of a series centered around Genius Loci.
Houston

- Bad Boss: He cares very little about Astrodude's well-being and often puts him in danger on missions, some of which he is completely aware of.
- Everyone Calls Him "Barkeep": He is frequently called "Houston" but has said that's not his real name.
- Jerk with a Heart of Gold: At times he has shown to care for Astrodude after all, like he sent a robot named "SAR" to rescue him while he was suffocating on Mars' atmosphere without a suit (as part of a test).
Astrodude's wife
Astrodude's wife who often checks in to make sure Astrodude is ok. She also provides helpful information to him through research.

- Can't Take Criticism: He NEVER accepts any form of it, and if his thoughts and opinions are not agreed on, he becomes Ax-Crazy.
- Everyone Has Standards: He might be Ax-Crazy, but when the Earth heads towards him, he is very concerned and tries to talk him out of it.
- It's All About Me: He can be very self centered, such as in "The HEAVIEST Planet Is..." where he keeps the trophy for being the heaviest celestial body in the Solar System, when the contest was which planet it was.
Inner Planets

Yeah, yeah, right. Thanks, I mean, of course I'm bigger than Pluto! I mean why wouldn't I be? I'll always be bigger, oh I'm Mercury baby! I'm the best!t
The first planet from the Sun.- Butt-Monkey: Is constantly pushed around a lot by Venus or The Sun.

Earth
Everyone will be happier this way.
The Third Planet from the Sun.- Jerk with a Heart of Gold: Before his Character Development, he liked to gloat about having a moon unlike Mercury or Venus, and doesn't like to count Phobos and Deimos on Mars, but he is much more nicer compared to hot-headed Venus.

The eighth planet from the Sun.- Cloudcuckoolander: He's wacky to say the least.

Everyone knows the Earth's a pretentious jerk!
- Everyone Has Standards: Despite his hatred towards how the planets treat the moons, when he sees that Jupiter isn't in the right state of mind when Europa chews him out, he calls her off.
