Kerbal

Kerbals are a species of short, green-skinned aliens from the planet Kerbin, the third planet from its sun, Kerbol. They stand at around 2 foot 4 inches, and have an enormously tall head, taking up an estimated 1/3 of their total body mass. Kerbals, as their culture suggests, are obsessed with space, rockets, and travelling into the unknown. They will often partake in long, arduous space travels to other planets in the Kerbol System

History
Similar to the human's BC and AD dating system, the kerbals use BEA and AEA, which stands for before exiting atmosphere and after leaving atmosphere, respectively

The kerbal species developed in around 50,000 years, and their culture in only around 5000, this is an incredibly short amount of time for a race to evolve. their awkward walking style is attributed to their short legs and recent bipedal status, as it's suspected they only became a bipedal species in the last 100,000 years. In the year 627 BEA, a famous kerbal astronomer, kerbileio Kerman, discovered a named the 6 other planets in the local solar system and their moons. This is commonly agreed to be the start of Kerablkinds obsessive space-culture.
