The sun will not change for the next 5 billion years. Much is still a mystery today. The second requirement is that the sun should exhibit nuclear fusion. The Sun has a layered structure that helps it create light and heat and diffuse them out to the solar system. Today the sun is considered a yellow dwarf, but once it has consumed the planets and collapsed it will be called a white dwarf (except the earth will be gone so there won't be anyone around to call it anything).

The sun has not changed so far as it has been in its main sequence stage for most of the time. It is about 4.5 billion years old and will live anothe 5 billion years. Imagine a bubbling pot of syrup to get an idea of what this convection zone is like. During this process, the temperature drops from 7,000,000 K to about 2,000,000 K. The convective zone helps transfer solar heat and light in a process called "convection." The Sun is at the center of our solar system. By Sharon Omondi on July 12 2017 in Environment. It efficiently provides the warmth and light that life needs to survive on Earth. From the core of the sun, energy moves to the radiative zone where it stays for approximately 1 million years then moves to the convective zone. By using ThoughtCo, you accept our, Journey Through the Solar System: Our Sun, What Is the Sun Made Of? The sun is responsible for the weather and the climate on earth. If it were possible, you could fit 1 million planet earths inside the sun. The reason for this is that the earth scatters the colors with higher wavelengths such as red, orange and yellow and not those with shorter wavelengths.

The sun weighs 1,989,100,000,000,000,000,000 kg. Short term exposure to the UV-radiation causes photokeratitis that is commonly called “sunburn of the eye.” However, the long term effect is that the eye develops cataracts later in life. In its composition, the sun needs to satisfy two critical conditions.

Consequently, the earth’s orbit will decay and spiral inward. The Sun may look yellow and smooth in our sky, but it actually has quite a mottled "surface." The sun is the closest star to the earth, and also the brightest object in the earth's sky. It has converted about half of its hydrogen into helium and will need about 5 billion more years to burn the rest. The sun is approximately 1,989,100,000,000,000,000,000 billion kg. The corona is the name given to the collective layers of the atmosphere, but it is also specifically the outermost layer. 5 billion years to come the sun will increase in size, encompassing the orbits of Mercury, Venus, and Earth. Eventually, the corona fades out into the vacuum of space. The dynamics of the hot gas that surround the Sun remain somewhat a mystery, although solar physicists suspect a phenomenon known as "nanoflares" are helping to heat the corona. Having occupied 99% of the Solar System, the other 1% is largely made up of the giant planets such as Jupiter and Saturn. It also influences a collection of planets, asteroids, comets, Kuiper Belt Objects, and cometary nuclei in the distant Oört Cloud. That's because it's not very massive when compared to such behemoth stars as Betelgeuse. Here, the 15.7 million-degree (K) temperature and extremely high pressure are enough to cause hydrogen to fuse into helium. Fast Facts about the Sun . Accordingly, the sun is estimated to be 4,600,000,000 years old. The Sun is 4.6 billion years old. It’s a main-sequence star or yellow dwarf star. The sun takes up to 250 million years to orbit the Milky Way's center. The UV radiation is classified into three namely UV-A, UV-C, and UV-B. Not only that, but it's a middle-aged star and astronomers refer to it informally as a yellow dwarf. Sun dogs are members of the halo family. The sun is plasma and not solid, it rotates slower at its poles than it does at its equator. The photosphere (the visible surface): normally when viewing the Sun (using only proper equipment of course) we see only the photosphere, the visible surface. This is equal to 109.2 times the earth's radius. It is so massive that it accounts for 99.86% of all the mass in our solar system. Hydrogen makes up approximately three-quarters of the mass of the sun while helium gas takes up the rest. The Sun is the star at the center of the Solar System.It is a nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy mainly as light and infrared radiation. It is believed that magnetic instabilities on the sun may be responsible for ice ages on earth. Don't worry - it still has approximately 5 billion years of hydrogen left to burn. Technically, it's classified as a G-type, main sequence star. At this point, the sun’s radiation becomes visible light. The Sun blows a steady stream of particles out from its outer layers, called the solar wind. That sunlight we all enjoy basking in on a lazy afternoon? Actually, the Sun doesn't have a hard surface as we know it on Earth but instead has an outer layer of an electrified gas called "plasma" that appears to be a surface. Even as recently as the 1800s, scientists did not know what the sun was made of or what its source of energy was. It is made up of hot plasma and magnetic fields and is almost a perfect sphere. Once photons get to the surface of the Sun, they travel away and out through space. However, if the earth’s spherical shape is maintained then there will be 960,000 earths fitting into the sun. It will continue to consume hydrogen in its core while emitting light and heat for another 5 billion years or so. It's one of the great features of the Sun, which is the most massive object in the solar system. Almost all life on earth is supported by the sun through photosynthesis. The sun is primarily made up of two gases - hydrogen and helium. As important as it is to us, in the grand scheme of the galaxy, the Sun is really sort of average. 70% of the its mass is Hydrogen gas while 28% is Helim. It is doing so by converting its mass into energy and light, as well as through its solar wind. It has a diameter of around 865,000 miles (1.4 million km), which is 109 times larger than Earth. The 2% of the sun’s mass represents the other gases. It’s the closest star to Earth, and it sustains life on Earth. It produces heat, energy, and photons. It's where the Sun's power plant resides. Amazing Facts About the Sun. If the earth is engulfed by the sun in its red giant stage, it will collide with gas particles. After this long duration of time, hydrogen and helium supply will be depleted and the sun will enter the Red Giant stage.

The sun is the most massive and largest object in the solar system. The diameter of the earth is 12,756 km while that of sun’s diameter is 1,392,000 km. 10. When all colors are put together the resultant color is white. Hydrogen makes up approximately three-quarters of the mass of the sun while helium gas takes up the rest. At the center of our solar system lies the sun. When the Sun is most active, it is in "solar maximum" and we see lots of sunspots and outbursts. Some cultures recognize the sun as a deity because of its significance to life on earth. The sun’s temperature is mainly influenced by its gravitational attraction. It is believed that the sun was formed approximately 4.6 billion years ago when there was a gravitational collapse in a molecular cloud. The sun is mostly made of hydrogen and helium. The hottest stars are type O and the dimmest are type M on the O, B, A, F, G, K, M scale. ThoughtCo uses cookies to provide you with a great user experience.

However, studies show the sun is slowly losing its mass over time. If the sun does not consume the earth then, the new earth’s proximity to the sun will make it impossible for it to support any life in it. All maps, graphics, flags, photos and original descriptions © 2020 worldatlas.com, Amazing Facts About The Victoria Amazonica, Countries Doing The Most To Combat Climate Change. Formation & evolution. Here are some interesting and fun facts about our Sun: It comes from a star, the closest one to Earth. What's left over will shrink to become a slowly cooling white dwarf, an ancient object that will take billions of years to cool down to a cinder. The sun’s rays have a component known as the Ultra Violent (UV) radiation. Therefore if the earth is squashed inside the sun, 1.3 million earths will fit into it. The sun’s energy then moves to the photosphere where the temperatures reduce further to about 10,000 degrees Fahrenheit. However, when observed from the earth, the sun’s color ranges from whitish-yellow to red. The sun has a surface area that is 11,990 times that of the earth. The sun is made up of colors as plentiful as those that form the rainbow. The hot gas plasma cools as it carries energy to the surface. The radiative zone lies outside of the core, stretching to a distance of about 70% of the Sun's radius, the hot plasma of the Sun helps radiate energy away from the core through a region called the radiative zone. The sun is primarily made up of two gases - hydrogen and helium. The mass of the sun can be measured using the Newton’s laws of motion and the law of gravity. The sun is a star at the center of our solar system and is thought to be around 4.5 billion years old. Countries Where Illegal Wildlife Trade Is A Major Threat To Wildlife. The lower cool layer (about 4,100 K) receives its photons directly from the photosphere, on which are stacked the progressively hotter layers of the chromosphere and corona. The Sun's structure is layered, with a very hot core, a radiative zone, a convective zone, a surface photosphere, and a corona.

It is made up of hot plasma and magnetic fields and is almost a perfect sphere. How often do these spots and flares happen? The Sun is mostly composed of hydrogen (70%) and Helium (28%). This article lists 30 Interesting and Fun Facts about The Sun that even kids will enjoy. The corona (outer atmosphere): during a solar eclipse a glowing aura can be seen around the Sun. Interesting, isn’t it? The first one is that it has to occupy the generally accepted range of its mass which is 1.4 x 1029 kg and 3.0 x 1032 kg. Some you might already know, and others will be totally new to you. 1.

Also known as parhelia, sun dogs are “mock-suns” that usually appear as bright spots on both sides of the sun. Sun Facts. As such it is these wavelengths that make us describe the sun as red, orange or yellow. The Sun blows a steady stream of particles out from its outer layers, called the solar wind.

The Sun's structure is layered, with a very hot core, a radiative zone, a convective zone, a surface photosphere, and a corona. Ultraviolet image taken of the sun by a NASA solar imaging satellite. It depends on where the Sun is in its solar cycle. How Much Of The Amazon Rainforest Is Left? The Sun is a middle-aged, yellow dwarf star.

The Sun is a star that is in the center of the Solar System; The Sun accounts for about 99.86% of the total mass of the Solar System. Here the core of the sun will heat up and get denser leading to an increase in the size of the sun so much that it will explode.
