The Sun traveled in human consciousness from being a god to become a yellow dwarf. And not from lack of respect. Knowledge made that possible. Man has overcome the myth of Icarus, who flew too close to the Sun with only a pair of wings made of wax.
About the Solar Orbiter missions
On February 9, 2020, NASA and ESA’s Solar Orbiter is set to launch on a mission to the Sun. It will get as close as 26 million miles from it. Don’t let yourselves be fooled: that is close. The temperature there is expected to be that of 970 degrees Fahrenheit. And it will do so after enduring minus 300 degrees Fahrenheit on the way.
A United Launch Alliance Atlas V rocket will launch from Cape Canaveral Air Force Station. Its mission is to complete the missing data about the Sun. The poles, as well as the solar winds, are to be explored. How does the magnetic environment of the poles help drive the Sun’s 11-year solar cycle and its periodic outpouring of solar storms? Those are questions, and the Solar Orbiter will help to be answered.
The craft will set a new speed record for a human-made object: at its closest approach in 2024, the Parker Solar Probe will be traveling at approximately 430,000 mph. A one-of-a-kind picture of how the Sun can affect the space environment throughout our solar system is expected from the mission.
The Sun’s past and future
The Sun is a 4.6 billion years old G-type main-sequence star. A G-type is often referred to as a yellow dwarf. The Sun formed approximately 4.6 billion years ago from the gravitational collapse of matter within a region of a large molecular cloud. 99.86% of the total mass became the Sun, and the rest flattened into an orbiting disk that became the Solar System.
The Sun currently fuses about 600 million tons of hydrogen into helium every second, converting 4 million tons of matter into energy every second as a result. This energy is the source of the Sun’s light and heat.
When hydrogen fusion diminishes to the point at which the Sun is no longer in hydrostatic equilibrium, the Sun will eventually turn into a red giant. Earth will become uninhabitable. But we’re safe for another five billion years. After this, it will become a dense type of cooling star known as a white dwarf. It will still glow and give off heat from its previous fusion.
