Scientists believe that the age of the Sun is 4.57 billion years. Schematically, a solar eclipse looks like this. The solar eclipse is a rare astronomical phenomenon, in which the Moon covers the Sun, completely or partially. Therefore, there is a periodic release of solar plasma into the surrounding space. The solar wind is formed due to the high temperature in the solar corona, the pressure of the overlying layers cannot be balanced with the pressure in the corona itself. The solar wind is a continuous stream of plasma coming from the solar atmosphere and filling the entire solar system. The sunspots themselves are formed under the influence of magnetic lines and their reconfiguration. Sunspots are darker areas on the solar surface, and they are darker because their temperature is lower than the temperature of the surrounding photosphere of the Sun. In fact, the core is a solar motor of its own kind thanks to it, our Sun emits heat and warms us all. In the solar core, nuclear energy is generated by nuclear fusion that transforms hydrogen into helium. The core of the Sun has the highest density and occupies approximately 25% of the total solar volume. Our Sun mainly consists of two elements: hydrogen (74.9%) and helium (23.8%). The solar magnetic field affects the Earth’s magnetic field. Intense solar emissions occur during these processes. What is the temperature of the Sun? The Sun surface temperature is 5778 degrees Kelvin (9940,73 ☏), but as it gets closer to the core, it increases even more – the Sun core temperature is 15.7 million degrees Kelvin (27 million degrees Fahrenheit).īesides this, the Sun has a strong magnetism there are north and south magnetic poles and magnetic lines on its surface, which are reconfigured at intervals of 11 years. The visibility of the yellow color is created by the atmosphere. The comparative size of the Sun and other planets.Īlthough the Sun seems yellow to us, its true color is white. If we compare the Sun with the Earth, then it is 109 times bigger than our planet and 333000 times more massive. The diameter of the Sun is 696342 km, weight – 1.988 x 1030 kg. The Sun is brighter than 85% of other stars in the galaxy, many of which are red dwarfs. Physical CharacteristicsĪccording to the astronomical classification of celestial objects, the Sun belongs to the G-class star. Here is the location of the Sun on the galactic map. In simple terms, we are not in the center of the Galaxy, but not in its border as well. Remoteness from the center of the galaxy is 7.5-8.5 thousand parsecs. The Sun located in the Milky Way galaxy, closer to the edge of Orion’s arm. Therefore, astronomers attribute the Sun to the class of yellow dwarfs. The Sun is a very small star because there are stars that are much bigger than the Sun. What kind of star is the Sun? What are characteristics of the Sun? How old is the Sun? We’ll answer these questions in our article.ĭespite its huge size relative to our planet (and other planets) on a galactic scale, the Sun is far from being the biggest star. If in ancient time, priests, shamans, druids worshiped the Sun as a god (there were solar gods in all pagan cults), now the Sun is actively studied by scientists: astronomers, physicists, astrophysicists.
Our Sun is truly a unique star, only because its luminosity has allowed to create conditions suitable for life on our planet Earth, which is at an ideal distance from the Sun Since ancient times, the Sun was under the attention of a man.
