Wonder Project I wonder What planets are suitable for life and humans? By Wendy Ho
Conditions suitable living creatures Image result for Conditions suitable for living creatures Some conditions that we need to survive are oxygen, temperature, atmospheric pressure, light, weather, and water. Please watch the following video to see the conditions in other planets https://www.youtube.com/watchv=Sk5FUDaP 5XU&list=PLw2cuKNQvZ2c5UQcwMS4Fg05 UdiT3-gs4
Image result for earth Earth There is many condition of earth to make it livable for human. These conditions are good for human on Earth. On earth we have water, oxygen, plants, food, shelter, sunlight and vitamins to survive. There is no free atmospheric oxygen, in any other planet in our solar system except for on Earth.
Image result for temperature Temperature The surface temperatures of the outer gas planets Jupiter, Saturn, Neptune and Uranus tend to be very cold because they are so far away from the sun. The average temperature of Jupiter is -244 degrees, and the surface temperature of Saturn is -300 degrees. Uranus's maximum temperature is -300 degrees, while Neptune's average surface temperature can be as low as -370 degrees.
Air Pressure Image result for air pressure Venus, Jupiter, Saturn, Uranus, and Neptune all have a substantially larger air pressure than Earth. If the human body was left unprotected on either of these planets, it would implode from a large amount of pressure. The human body on Mercury would have the same reaction as the moon or Mars.
Lights Because planets do not have nuclear fusion, they do not produce their own light. Instead, they shine with light reflected from a star. When we see planets in the night sky, such as Venus, the so-called "Evening Star," we're seeing reflected sunlight.
Image result for weather Weather On Mercury temperatures vary from -183C to 427C between the scorching subsolar point and freezing poles. On Venus with an atmosphere that s choked with carbon dioxide and nitrogen and suffused with sulphuric acid, glimpses of sunshine are unlikely. Mugginess doesn t come close to describing the experience of sweating it out on the rocks with 92x the atmospheric pressure of Earth bearing down on you, trying to cool off in 480C heat. These condition are bad because of the coldest and hottest temperature
Image result for weather Weather continued Mars is the fourth planet from the Sun, Mars may have seen some heavy rain and snow in the past but visitors these days would have to content themselves with strapping on their ice skates to explore the chilly polar regions. Expect to see blue sunsets and sunrises. Passing sandstorms are dangerous to humans. Jupiter is a gas planet, made up of hydrogen and helium. At 318 times the size of Earth, Jupiter gives off more heat than it gets from the Sun. Storms are highly likely as high pressure forces helium to become liquid, causing heavy rain, and winds of up to 360kph may be expected. Watch out for ammonia clouds, likely to be a common feature. I think it could be hazardous to live on Jupiter because of the gas and ammonia.
Image result for weather Weather continued On Uranus the Stormy weather is forecast for this gas-and-ice planet. Blue clouds of methane gas are expected, and visitors are advised to wear thermals to ward off the -197C chill. Neptune is the blue planet furthest from the Sun is the coldest, with temperatures plummeting to - 224C. Another gas giant but with an icy core, expect similar weather to Uranus but at the more extreme end. Winds can reach 2,100kph We can t live there because the wind and cold temperatures.
Image result for water Water Evidence points to water on other planets in our solar system. In 2015, NASA confirmed that liquid water flows intermittently on present-day Mars. Also in 2015, scientists used data from NASA's Cassini mission to discover that a global ocean lies beneath the icy crust of Saturn's moon Enceladus. Scientists believe that Jupiter's moon Europa has a subsurface ocean as well.
Conclusion There are no planets suitable for life other then earth! On some planets we can go if we wear a spacesuit.
