Features of the Sun

Known as the Astro King, being the center of the planetary system to which our planet belongs, the Sun is the main source of energy, heat and light for all beings on Earth, which would take barely a week to begin to die and disappear if someday his light will run out.


Studied with great passion for physicists, astronomers and chemists, the Sun is also a field of research, as it is suspected that in its operation there is much that can be understood about the formation of our universe, the creation of chemical elements and the appearance of life on Earth.

On this occasion, we will then present a series of characteristics of the Sun, so that we know a little more about this star, which with its light and strength makes it possible to all cycles function perfectly in nature. Here are some of the sun’s qualities:

Physical characteristics of the Sun

Although most believe that the sun is a planet, it is actually a star, classified by astronomers as a yellow dwarf star, which is characterized by constantly turning hydrogen into its nucleus, through a fusi process nuclear weapon. Likewise, this condition warns us that one day the Sun will be extinguished, because it is what happens when a yellow dwarf finishes consuming its reserves of Hydrogen, in doing so, it is extinguished.

However, it takes about ten million years to do so. As for our sun, its age has been estimated at about four thousand six hundred or four thousand seven hundred million years, so it still has about six million years to live.

Likewise, astronomers believe that its structure is almost spherical, presenting a slight flattening at the poles. Similarly, his radii on esbut in some six hundred and ninety and six thousand two hundred and fifty-six kilometers in length (696,256 km) has been estimated.

For its part its total dimension has been fixed at one million three hundred and ninety and two thousand three hundred and fifty kilometers (1,392,350 km) that is one hundred times our planet.

Distances between the planets and the Sun

The Sun is the center of the Solar System, around which eight planets rotate, including planet Earth, which hold different distances relative to this star.

According to measurements made by astronomers and physicists, the planets are within the following distances of the Sun: Mercury (fifty-seven million kilometer; 57,910,000 km); Venus (one hundred and eight million two hundred thousand kilometers; 108,200,000 Km); Earth (one hundred and forty-six million six hundred thousand kilometers; 146,600,000 Km); Mars (two hundred and twenty-seven million nine hundred and forty thousand kilometers; 227,940,000 Km); Jupiter (seven hundred and seventy-eight million three hundred and thirty thousand kilometers; 778,330,000 Km); Saturn (one billion four hundred and twenty-nine billion four hundred kilometers; 1,429,400,000 km); Uranus (two billion eight hundred and seventy million nine hundred and ninety thousand kilometers; 2,870,990,000 km); Neptune (four five hundred four billion three hundred thousand kilometers; 4,504,300,000 km).

Scientists have also estimated that a ray of sunlight takes about eight minutes to reach from the Sun’s surface to Earth. Similarly, the Earth takes a total of three hundred and sixty-five days to turn the sun completely, which determines the duration of a year, which can sometimes (every four years) take three hundred and sixty-six years.

Gravity of the Sun

In terms of its gravitational force, the Sun has a gravity equivalent to 274 m/s2 (about twenty-seven eatnine nine Earth gravitys) which represents an immense gravitational force that causes the rest of the planets to orbit around them. Likewise, astronomers have been able to determine that the Sun suffers from polarity changes every eleven or twelve years, without this seeming to significantly affect planetary orbits.

Storms and sunspots

Like any space body, the Sun also has phenomena on its surface, among which are so-called solar storms, which almost always happen after the solar cycle has reached its maximum activity.

They are closely linked to the sun’s polarity changes, and the last is estimated to have taken place in 2011, lasting for two years. During a solar storm there are hundreds of violent plasma explosions, fulgurations, as well as coronal mass ejections.

Similarly, the Sun counts on its surface with dark spots, which are called sunspots. Basically it is a solar region that has a lower temperature than the region through which it is surrounded. Astronomers have come to calculate that a single sunspot can measure up to twelve thousand kilometers (12,000 km) so it is said that in a single sunspot can fit the Earth.

Implications of the Sun on Earth

Considered the maximum source of energy, the Sun provides planet Earth with the necessary conditions for life to be in it. In this sense one of the fundamental contributions is to have a direct impact on photosynthesis, which makes possible the existence of plants, sustenance of the food chain.

It also produces the heat and light needed for vital processes, such as water condensation, rain cycle, or other weather events such as storms, which it produces by heating air masses.
