The Solar Sistem few years ago

The solar sistem had nine planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn , Uranus, Neptune, Pluto.

One astronaut went to Pluto and he was investigating this planet when he found a new alien form. These aliens caught him and the aliens showed their problems and the astronaut helped to the aliens. He anlysed the planet and he found the problem. A carnivorous plant, every day ate aliens and the Solar light. The astronaut injected an antiplant virus and the plant died; in that moment a big sunshine iluminated Pluto and in this planet, the aliens lived in good conditions.

Finally, the aliens helped to the astronaut to build the spaceship. He returned to the Earth.
