It is a well-known scientific fact that without the sun, whose light we are illuminated and warmed by its warmth, there would be no human life on earth. It’s amazing that the 4.6 billion year old sun has more features than we see.
For this reason, in the content we have prepared, we have brought together both the information you need to know about the sun and the facts you have never heard of. Here is the information about the sun…
What is the Sun?
The sun, one of an estimated 200 billion stars, is located at the center of the solar system. The sun, which contains hot gases, emits radiation in the form of heat and light. These gases, which make up 99% of its mass, enable the sun to have heat energy. For this reason, the surface is believed to be 5,500 degrees Celsius and the core 15.5 million degrees Celsius. The sun, which brings the solar system together, is important for global warming and lighting. The sun is 109 times the diameter of the Earth, 333 thousand times its mass and 1.3 million times its volume. The sun, which revolves around the Milky Way galaxy, moves here at a speed of 828,000 km/s.
What are the structure and properties of the sun?
The sun contains 71% hydrogen, 26.5% helium and 2.5% other gases. Therefore, the sun, which we can describe as a fireball, has the property of emitting a lot of light. The sun, like the earth, is made up of layers. Because each layer consists of different chemicals, explosions always take place in the sun. There are three layers in the sun, the inner and outer regions. This; It is divided into radiant zone (radiation zone), convection zone (convection zone) and core (core). The core forms the center of the sun, while the radiant zone surrounds the core. The convection zone is the outer layer of the inner layers and covers 30% of the radius. Also, the sun has 3 different atmospheres, the photosphere, the chromosphere and the corona or crown.
Located 150 million kilometers from Earth, the sun completes its orbit around the Milky Way in exactly 230 million years. The sun revolves around itself as well as around the center of the Milky Way. Because the sun is not a solid object, every part of it rotates at different speeds. The sun, which revolves around itself every 25 days in the equatorial part and every 36 days in the polar part, has an axis of rotation that is tilted 7.25 degrees from the plane of the orbits.
What are the effects of the sun on the earth?
The sun, the world’s source of heat, light and energy, directly influences many events such as weather, climate, season, ocean currents and radiation belts. The sun, which influences the existence of life on Earth, is a resource that people need to live. Due to the special shapes of both the Earth and the Sun, not every region in the sphere we live in has the same temperatures. Since the sun revolves around itself in 25 days at the equator and 36 days at the poles, the temperatures of these areas of the earth differ.
Interesting facts about the sun
– Many ancient cultures worshiped the sun as a deity. (Egypt, Indian, European and Mesoamerican)
– Anaxagoras, a scientist and philosopher, BC. He first suggested that about 450 suns were stars.
– Our modern day calendar is based on the movement of the sun around the earth.
– The sun is currently 4.5 billion years old.
– The sun is the largest object in the solar system and is 333,000 times the size of the Earth.
– The sun occupies about 99.86 percent of the total mass of the solar system.
– The gravity of the sun unites the earth and all the other planets in a small space called the solar system.
– The gravity of the sun is 28 times stronger than that of the earth.
– The sun produces the energy that sustains all life on Earth through a process known as photosynthesis.
– The temperature of the sun ranges from about 5500 to 6000 degrees Celsius.
– It takes a million years for the heat and energy from the sun’s core to reach the surface.
– When magnetic energy accumulated in the sun’s atmosphere is suddenly released, it causes a rapid change in brightness known as a solar flare.
– The amount of energy released by a flare is equivalent to the simultaneous detonation of millions of 100 megaton hydrogen bombs.
– The sun is actually a mixture of all colors that appear white to the eye. It appears to have different colors during the day due to a movement known as atmospheric scattering.
– The sun is the closest star to the earth, which is called the most perfect sphere in the universe and is observed.
– Some parts of the sun are less hot than others. That’s why those parts look dark. These are called sunspots.
– Green light is a momentary optical illusion that occurs at sunrise or sunset when light is deflected from the sun to Earth.
– Sunspots have a very strong magnetic field that inhibits energy convection and therefore explains their lower temperature.
– Sunspot cycles repeat every 11 years and coincide with solar flares.
– The sun is shrinking at 1.5 meters per hour, which worries astronomers.
– The sun rotates at different speeds, with the fastest at the equator.
– The rotation period of the sun at the equator is about 26 Earth days and at the poles about 36 Earth days.
– The sun completes one revolution around the galaxy every 250 million years.
– The composition of the sun consists of 91% hydrogen, 7.8% helium and 1% other gases.
– Helium is the most abundant element in both the sun and the universe. But it is very difficult to find on earth.
– The photosphere makes the sun appear solid and is an opaque layer of gas. It is also cooler than the outer layer, the corona, which emits light.
– The sun is currently in the yellow dwarf phase. This huge fissile material will remain intact for another 5 billion years.
– When the sun’s energy explodes, it will spread to the red giant and reach the power to destroy all the planets.
– The sun is a sphere of gas and has no solid surface.
– The ultraviolet rays of the sun have antiseptic properties. The process by which energy moves from the sun to the earth is known as radiation.
What are the 5 characteristics of the sun?
It rotates both around itself and around the Milky Way galaxy, actually emitting white light, completes its orbit around its axis in 25 days, and rotates its features from the sun from west to east.
What are the characteristics of the sun?
Under the characteristics of the sun; It is not solid but plasma, consists of gases, is 109 times wider than the Earth, is at the center of the solar system and has a strong magnetic field.
What color is the sun?
The true color of the sun is white, due to the combination of different colors.
How many suns are there?
Of the estimated 200 billion stars, the sun is the only star that has heat and light energy.
What’s in the Sun?
In the sun; It contains neon, magnesium, phosphorus, sulfur, potassium, iron, sodium, 78.5% hydrogen, 19.7% helium, 0.86% oxygen and other elements.
What does the sun give us?
While the sun illuminates and warms the earth, it also protects humans from many diseases by providing vitamin D.
Why is the sun so hot?
When the hydrogen in the sun combines with helium, heat energy is produced. The reason why the sun is so hot is that it is a star.
How old is the sun?
The sun is 4.6 billion years old.
