Naturally occurring fusion reactions (for example, the reactions that fuel the Sun) occur due to extreme gravitational forces. The minimal mass required to create such a large gravity in the core thus igniting hydrogen fusion, is 0.08 solar masses. This is roughly 75 times the mass of Jupiter.
What else can I help you with?
Why does the core of the sun need to be well over a million degrees?
The high temperature of the Sun's core is necessary for nuclear fusion to occur. Fusion reactions at this temperature produce the tremendous amount of energy that allows the Sun to shine and sustain life on Earth.
Temprerature of the core of the sun?
The temperature of the core of the sun is around 15 million degrees Celsius. This extreme heat and pressure are what enable nuclear fusion to occur, creating the sun's energy.
Which layer of the sun has the densest material?
The core of the Sun is the layer that contains the densest material. It is where nuclear fusion reactions occur, resulting in high temperatures and pressures, which contribute to the density of the core.
What does the word core mean to do with sun?
In the context of the sun, the core refers to the central region where nuclear fusion reactions occur. These reactions generate energy by converting hydrogen into helium, powering the sun's heat and light. The core is the hottest and densest part of the sun.
What is the temperature on the inner core of the sun in degrees Celsius?
The temperature at the inner core of the sun reaches around 15 million degrees Celsius (27 million degrees Fahrenheit). This extreme heat is generated by nuclear fusion reactions that occur at the core.
Where does the fusion reacion occur on the sun?
Fusion occurs in the core of the Sun
Where does the fusion reaction occur in the sun?
Fusion occurs in the core of the sun and other stars.
Why is the Sun a star while Jupiter is not?
Although Jupiter is comprised of similar materials to the Sun - mainly hydrogen and helium, it does not have enough mass to heat the core of the planet to 10,000oK. This is a requirement for nuclear fusion to occur and without that, Jupiter is not a star, but a planet. For Jupiter to become a star, it would have to accumulate 75% more mass to achieve this.
Does the layer of fire on the sun occur in the suns core?
There is no fire in the sun, that is a chemical process. The process in the core is thermonuclear fusion.
Does hydrogen fusion occur in the corona?
Hydrogen fusion does not occur in the corona of the sun. Fusion reactions occur in the sun's core where conditions are hot and dense enough for hydrogen nuclei to combine to form helium, releasing energy in the process. The corona is cooler and less dense than the core, so fusion cannot take place there.
How does nuclear fusion occur in the sun's interior core?
High temp and pressure
What layer of the sun does fusion occur?
Nuclear fusion occurs in the solar core.
Why only in the sun's core does nuclear fusion occur?
The rest of the sun is too cold and too low pressure.
What is the site of nuclear fusion on the sun?
If you are asking where does solar nuclear fusion take place, then that would be at the core of stars.
What is the order in which elements undergo fusion on the sun?
In the core of the Sun, hydrogen atoms fuse to form helium in a process known as hydrogen fusion. This is the primary fusion process occurring in the Sun. As the core hydrogen is depleted, helium fusion into heavier elements like carbon and oxygen will occur in later stages of the Sun's evolution.
What is one place with temperatures high enough for nuclear fusion to occur?
Interior of the sun.
What is the innermost layer of the sun called?
The innermost layer of the sun is called the core. It is where nuclear fusion reactions occur, generating the energy that powers the sun's immense heat and light.
