Neptune, the eighth planet from the sun, cannot support life according to NASA. Being so far from the sun makes Neptune a very cold planet, with temperatures reaching as low as -361.

One day on Neptune is about 16 hours long. It takes approximately 165 Earth years for it to make a complete orbit around the sun. Neptune is a gas giant, meaning it doesn't have a solid surface. The atmosphere is made of methane, ammonia and water, which cannot be breathed by humans.

Scientists will continue to study Neptune; however, they do not expect to find a way for it to sustain human life.
