Can humans survive if how many kilometers from the Sun?

The Sun is the central star of the Solar System, about 149.6 million kilometers from Earth and has a surface temperature of about 5,505 degrees Celsius. The light emitted from this giant fireball supports most of the live on Earth through photosynthesis and regulate gas for our planet. With the tremendous amount of heat that the Sun radiates, anything flying near it is burned down.

With modern science technology, today people have built spacecraft that takes us to explore new areas of space. But even though we tried very hard, we still could not 'touch' and keep a certain distance from the Sun because the main reason was that the temperature was too high.

According to Popular Science, the heat from the Sun is very large but when it spread out in the vacuum environment of the universe it quickly cooled down. In particular, when we are located 3 million miles away from the Sun (ie more than 4,828,000 km), we only have to suffer from the heat of about 120 degrees C. With the current astronaut suit, people can bear heat is equivalent to this temperature.

But when crossing the 3 million mile mark and getting closer to the Sun, the problem will be different, you will surely face death. Because then, the astronaut's suit will become a mini sauna, causing the person inside to experience symptoms such as dehydration, loss of consciousness and eventually death from heatstroke.

If we sit in a modern space shuttle with the ship's insulation, which can withstand the heat of more than 2,593 degrees Celsius, we can get closer to the Sun, at a distance of 1.3 million miles ( more than 2,092,000 km). If you get closer the ship will not be able to withstand the terrible high temperature and will quickly be destroyed, exploding in space.

In 2018, NASA plans to launch a spacecraft, Solar Probe Plus, to discover the mystery of the Sun at a distance of 6 million kilometers. Solar Probe Plus has a shield made of 11.4 cm thick carbon fiber composite material and is equipped with special heat-dissipation tubes that can release the heat absorbed into space to help it withstand the temperature. outside the spacecraft about 1,370 degrees C.
