1. Can humans live on the planet? If no, why not?

- Living on Neptune? People could not survive on Neptune because it does not have oxygen.

2. What types of accommodations are on the planet so that humans can live?

-To find life on Neptune, the planet would need to have a source of energy that bacterial life can exploit, as well as a standing source of liquid water.

3. What types of clothing would humans have to wear to survive?

-Everything can keep you warm

4. What is the quality of the atmosphere of the planet?

-It mostly consists of hydrogen and helium, with trace amounts of methane, water, ammonia and other ices. But unlike the other gas planets in the Solar System, Neptune’s atmosphere has a larger proportion of the ices. It’s the methane in the planet’s upper atmosphere that give it its bright blue color.

5. How would humans adapt to these conditions?

-They need special food, special clothing, oxygen.

6. How would humans protect themselves on the planet?

-Use guns, nuclear weapons, armor

7. How would humans navigate to get around the planet?

-GPS, tour guide

8. What activities could humans be involved in while visiting the planet?

-You could inhabit it by building a bio-dome and an ice-retrieving robot. You could use a C02 Converter or a machine that converts helium and hydrogen to oxygen. Or you could hydroponically plant a flower to grow.

9. Could they take side trips to any moons?
