![]() ![]() Does the Sun Have Different Layers Like a Planet? We perceive this energy release as light and heat coming from the Sun. This process turns hydrogen into helium and releases a tremendous amount of energy in the process. In terms of star formation, ignition means that nuclear fusion was triggered nuclear. Eventually, the right combination of extreme temperature and pressure, which can only be brought about through having enough mass (which is why Jupiter isn’t a failed star), caused the Sun to ignite. Nearly all of the matter creating the Sun is just two elements: 70.6% is hydrogen, while 27.4% is helium.Īs the density of material increased at the heart of the spinning disc, so did its temperature and pressure. The remaining 0.2% formed the planets and asteroids. Gravity was at its highest here, and it eventually accumulated 99.8% of the available matter in the solar system to create the Sun. At the center of the disc, the Sun began forming. This nebula began spinning, causing the material to flatten out into a disk. When a shockwave from a nearby supernova struck this dust cloud, it collapsed to form a solar nebula. How Was the Sun Formed?Ĥ.5 billion years ago, the Sun and its system of planets that we see today only existed as a cloud of dust. Let’s peel its complex structure one layer at a time. ![]() However, as it evolved, nuclear fusion resulted in hydrogen, helium, and other elements inside the Sun. When the Sun began forming 4.5 billion years ago, it consisted of only gas and dust. Keep reading to get more details on the temperature in each of the Sun’s layers. At the Sun’s visible surface, the temperature can be as ‘cool’ as 1,100☏ (600☌).įinally, as we make it to the outer reaches of the corona, the temperature rises once again to as much as 44,000☏ (24,400☌). This is not an easy question to answer because it depends very much on where you stick your thermometer!Īt the heart of the Sun, the temperature reaches 17 million ☏ (9.4 million ☌), hot enough for nuclear fusion to be sustained. Does the Sun Have Different Layers Like a Planet?. ![]()
