The Sun continuously loses mass through solar wind and coronal mass ejections, which can have significant impacts on the Earth and the entire Solar System.
Zusammenfassung
The article discusses the colorful phenomenon of the Sun's mass loss, which is manifested through auroras in the Earth's atmosphere. Coronal mass ejections from the Sun, triggered by solar flares, can release an enormous amount of energy and charged particles that interact with the Earth's magnetic field, causing geomagnetic storms and auroras.
The article explains that the solar wind, which carries about 2 million tons of matter per second, accounts for a significant portion of the Sun's mass loss, along with the energy it emits through radiation. While the Sun is losing mass, it is also being replenished by the influx of asteroids raining on its surface, though this is not enough to compensate for the overall mass loss.
The article also discusses the long-term implications of the Sun's mass loss, such as the gradual recession of the Earth and other planets from the center of the Solar System, and the eventual transformation of the Sun into a red giant, which will engulf the Earth's orbit and remove a significant portion of the Sun's mass.
The author concludes by drawing a parallel between the Sun's natural mass loss and the concept of losing mass for personal health reasons, suggesting that mass loss is not always beneficial for promoting a bright future.
Statistiken
The Sun loses about 2 million tons of matter per second through the solar wind.
The mass lost by the Sun through radiation is about half the amount lost through the solar wind.
The Sun loses about 6 million tons of mass every second through a combination of radiation and wind.
During the Sun's 12 billion-year lifespan on the Main sequence, it will lose 0.0004 of its mass.
At the end of its life, the Sun will become a red giant and lose two-fifths of its mass.
Zitate
"Coronal mass ejections are triggered by solar flares in which strong magnetic field lines on the surface of the Sun cross each other, tear apart and reconnect like giant ropes glued with hot gas."
"The plume expelled during a coronal mass ejection typically carries about a billion tons of hot gas at speeds between a few hundreds to a few thousands of kilometers per second that cross the Sun-Earth separation over a timescale between a week and 15 hours, respectively."
"As a result of the mass loss from the Sun, Earth and other planets slowly recede in their orbits from the center of mass of the Solar system."
