Planet Penny 1 (based off an RP)

Penny was one of the top astronauts of the 21st century, mainly because she is one of 100 people who arent affected by the power of space. One day, she was assigned a mission to find a new world where we could grow more food, but during the travel, her ship crashed into a comet. While she escaped via the escape pod, her oxygen tank was dented, and now more oxygen shot into her body than ever before. Desperate, she got out of her escape pod as she swelled up, but she kept expanding until she was the same size as pluto. Now she is a floating dwarf planet, and the next mission will be a rescue...
