Although we are getting closer to other planets, we are still a long way from visiting these. But let’s move so far into the future, when humans have hypothetically evolved so much that we can breathe on other planets without help, and find a way to reach them in the foreseeable future.
Mercury
Mercury is one of the four terrestrial planets and the smallest and closest planet to the Sun in the Solar System. Unfortunately, it does not offer good living conditions, as temperatures range between -80 and 430 degrees Celsius. Due to the unique resonance of 3: 2 rotation of the planet around the axis, there is a great variety of surface temperatures. A man without protection on this planet, which orbits the Sun in 88 days, would not survive more than 90 seconds.
Venus
If man had the opportunity to step on the second brightest object in the night sky after the Earth's Moon, he would have exactly one second to look at it. Of all the terrestrial planets, it has the densest atmosphere, which is predominantly composed of carbon dioxide (98 percent), and the air pressure at the surface is 90 times greater than on Earth. It is covered with an opaque layer of glittering clouds, and above the layer of carbon dioxide are thick clouds composed of sulfur dioxide and sulfuric acid. It is a very hot planet, with an average temperature of 426 degrees Celsius and mercury rising as high as 500 degrees Celsius.
Mars
The red planet - the characteristic red color is due to the presence of iron oxide on the surface - where Donald Trump and Elon Musk measure, is the first candidate for colonization, although without protection a man would spend only 80 seconds on it. Mars' atmosphere is made up of 95 percent carbon dioxide, three percent nitrogen and 1.6 percent argon. In contrast to Venus, it is extremely cold on Mars, as the average temperature is -63 degrees Celsius, but it does not heat up more than 20 degrees Celsius in the spring.
Jupiter
The largest planet within our Solar System is also a hostile environment for humans, as we would only spend one second on it. As clouds rotate in opposite directions at different latitudes, this causes storms and turbulence, and winds often reach speeds of up to 600 km / h, against which Hurricane Dorian is just a breeze. The atmosphere is made up of 86 percent hydrogen and 14 percent helium, and there are also ammonium clouds, so it’s hard to imagine that man could ever survive in this toxic cocktail.
Saturn
The gas giant is the second largest planet in the Solar System after Jupiter and is even less hospitable than Jupiter, as a human would spend even less than a second on it. In addition to gaseous clouds, life is prevented by strong winds that reach unimaginable speeds - up to 1800 km / h - and local tornadoes would turn a person into cosmic dust in a split second. The atmosphere of the planet with characteristic rings is marked by hydrogen (75 percent) and helium (25 percent).
Uranium
The seventh planet from the Sun boasts the coldest atmosphere in the Solar System, and temperatures also drop 224 degrees below freezing. It is difficult to estimate how much time a man would spend on the surface, as it would be very difficult to land on it. It consists mainly of gases and ice and has virtually no solid surface. Uranium's atmosphere contains about 85 percent hydrogen, 15 percent helium, two percent methane and traces of acetylene.
Neptune
Like many other planets in our solar system, Neptune is not a good host, as strong winds destroy everything in their path in an instant. Its atmosphere has the fastest winds in the Solar System. Sometimes they travel even faster than sound, with speeds all the way up to 2000 km / h. Although it is the smallest gas giant, it has a larger mass than Uranus. Because it is quite far from the Sun, it receives very little heat. The temperature of the highest layers of the atmosphere therefore does not exceed -218 degrees Celsius.
Planet Earth is therefore the most hospitable planet in our Solar System.
