interesting facts about SUN

Over the direction of human history, the Sun has been feared and worshiped. Rightfully so. What our ancestors knew on a fundamental level was once that the Sun provides a vital ingredient for most of the lifestyles on Earth. Without the energy supplied through sunlight, vegetation can't grow, and without vegetation, animals do not have a supply of nourishment. However, what we know these days that our ancestors did now not is simply how ways reaching the scope of the Sun's influence is.

As our scientific knowledge has extended so too has our understanding that the Earth is simply a piece in the large the structure we know as the Solar System. What we have additionally discovered is that even though different planets and bodies in the Solar The system may also not possess life, the Sun is simply as influential to them.

What is the Sun?

The Sun is what is acknowledged as a primary sequence star; that is, a sphere composed primarily of the two gases hydrogen and helium such that positive conditions are met. The first condition is that it needs to have a mass falling inside a certain range. Though debated, this vary is commonly accepted to be between approximately 1.4 x 1029 kg and 3.0 x 1032 kg. (This range is often described as at least 75 times the mass of Jupiter and no extra than 150 times the mass of the Sun itself.) The 2d and most necessary condition is that nuclear fusion should be present. Nuclear fusion is the system whereby two lighter atomic nuclei join or “fuse” together to produce a heavier atomic nucleus. In the context of stars, hydrogen is the lighter and helium the heavier.

what's the size of the sun?

The size of the Sun in contrast to the greatest acknowledged stars (red giants) is no longer very big. However, if compared to the most frequent kind of star in the universe, the purple dwarf, the Sun is quite a bit larger. Thus, the Sun is no longer the largest type of superstar in the universe, but it is definitely large than most.

As ways as the Sun’s mass compared to different bodies discovered in our solar system, the Sun is without problems the most massive. The Sun alone carries 99.8% of the total mass in the Solar System.

In terms of size, the Sun has a diameter of roughly 1.4 million kilometers (870,000 miles). To put this in perspective, this is nearly 110 times the diameter of the Earth. What this capability is that about one million Earth’s may want to fit inside the Sun.

Facts about the SUN :

✤✤ The Sun accounts for 99.86% of the mass in the solar system. It has a mass of around 330,000 times that of Earth. It is three-quarters hydrogen and most of its last mass is helium.

✤✤ Over one million Earth’s could in shape inside the Sun. If you have been to fill a hollow Sun with spherical Earths, somewhere around 960,000 would suit inside. However, if you squashed these Earths to ensure they're used to be no wasted space then you may want to fit 1,300,000 piles of earth inside the Sun. The surface region of the Sun is 11,990 times that of Earth.

✤✤ One day the Sun will consume the Earth. The Sun will proceed to burn for about 130 million years after it burns thru all of its hydrogens, alternatively burning helium. During this time it will expand to such a size that it will engulf Mercury, Venus, and Earth. When it reaches this point, it will have become a red massive star.

✤✤ The energy created by using the Sun’s core is nuclear fusion. This huge quantity of energy is produced when 4 hydrogen nuclei are combined into one helium nucleus.

✤✤ The Sun is nearly the best sphere. Considering the sheer size of the Sun, there is only a 10 km distinction in its polar and equatorial diameters – this makes it the closest thing to a best sphere located in nature.

✤✤ The Sun is traveling at 220 km per second. It is round 24,000-26,000 light-years from the galactic center and it takes the Sun about 225-250 million years to complete one orbit of the center of the Milky Way.

✤✤ The Sun will eventually be about the dimension of Earth. Once the Sun has completed its red large phase, it will collapse. Its large mass will be retained, however, it will have a quantity similar to that of Earth. When that happens, it will be known as a white dwarf.

✤✤ It takes eight minutes for light reach Earth from the Sun. The average distance from the Sun to the Earth is about 150 million km. Light travels at 300,000 km per second so dividing one by way of the other offers you 500 seconds – eight minutes and twenty seconds. This energy can reach Earth in mere minutes, however, it takes millions of years to tour from the Sun’s core to its surface.

✤✤ The Sun is halfway thru its life. At 4.5 billion years old, the Sun has burned off around half of its hydrogen stores and has ample left to continue burning hydrogen for every other 5 billion years. Currently, the Sun is a yellow dwarf star.

✤✤ The distance between Earth and Sun changes. This is because the Earth travels on an elliptical orbit direction around the Sun. The distance between the two ranges from 147 to 152 million km. This distance between them is one Astronomical Unit (AU).

✤✤ The Sun rotates in the opposite route to Earth with the Sun rotating from west to east instead of east to west like Earth.

✤✤ The Sun rotates extra rapidly at its equator than it does shut to its poles. This is recognized as differential rotation.

✤✤ The Sun has a powerful magnetic field. When magnetic power is released by way of the Sun during magnetic storms, solar flares appear which we see on Earth as sunspots. Sunspots are dark areas on the Sun’s surface prompted by using magnetic variations. The reason they show up dark is due to their temperature being much lower than the surrounding areas.

✤✤ Temperatures inside the Sun can reach 15 million degrees Celsius. Energy is generated thru nuclear fusion in the Sun’s core – this is when hydrogen converts to helium – and because objects commonly expand, the Sun would explode like a substantial bomb if it wasn’t for it’s tremendous gravitational pull.

✤✤ The Sun generates solar winds. These are ejections of plasma (extremely hot charged particles) that originate in the layer of the Sun understands as the corona and they can travel thru the solar system at up to 450 km per second.

✤✤ The atmosphere of the Sun is composed of three layers: the photosphere, the chromosphere, and the corona.

✤✤ The Sun is classified as a yellow dwarf star. It is a primary sequence star with surface temperatures between 5,000 and 5,700 degrees celsius (9,000 and 10,300 degrees Fahrenheit).

✤✤ The Aurora Borealis and Aurora Australis are caused by the interaction of solar winds with Earth’s atmosphere.

What type of star is the Sun?

Although we think of our Sun as a unique celestial body, it is, in fact, one of the trillions of stars in the universe. On top of this, the Sun is rather ordinary as far as stars go. The official classification for our Sun is G V star, which means that it is a main-sequence star whose surface temperature is between 5027°C and 5727°C.

Some estimates for stars similar to the Sun in the Milky Way galaxy alone are as high as 7 billion. If this number is correct, there could be over one-trillion stars that are roughly the same as our Sun in the universe.

Does the Sun have another name?

While our Sun does not have a proper scientific name, it does have another common name:~ Sol. This name originates from the ancient Roman god of the Sun, Sol. This alternate name is where we get the term “solar system” which means the system of the Sun.
