The innermost layer of the sun is the core. With a density of 160 g/cm^3, 10 times that of lead, the core might be expected to be solid. However, the core's temperature of 15 million kelvins (27 million degrees Fahrenheit) keeps it in a gaseous state.
In the core, fusion reactions produce energy in the form of gamma rays and neutrinos. Gamma rays are photons with high energy and high frequency. The gamma rays are absorbed and re-emitted by many atoms on their journey from the envelope to the outside of the sun. When the gamma rays leave atoms, their average energy is reduced. However, the first law of thermodynamics (which states that energy can neither be created nor be destroyed) plays a role and the number of photons increases. Each high-energy gamma ray that leaves the solar envelope will eventually become a thousand low-energy photons.
The neutrinos are extremely nonreactive. To stop a typical neutrino, one would have to send it through a light-year of lead! Several experiments are being performed to measure the neutrino output from the sun. Chemicals containing elements with which neutrinos react are put in large pools in mines, and the neutrinos' passage through the pools can be measured by the rare changes they cause in the nuclei in the pools. For example, perchloroethane contains some isotopes of chlorine with 37 particles in the nucleus (17 protons, 20 neutrons). These Cl-37 molecules can take in neutrinos and become radioactive Ar-37 (18 protons, 19 neutrons). From the amount of argon present, the number of neutrinos can be calculated.

How hot is the core of the sun in kelvin?
The core of the sun is about 15 million Kelvin.
what is hotter earth's core or the sun?
The sun.
Is the sun hotter then the core?
of the earth yes the core of the earth is around the temp. of the outside of the sun
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.
Is the sun hotter than the core of the earth?
The reason why the surface of the sun is colder than the sun's core is because the surface is father from the core of the sun.As you get deeper and closer to the sun's core,it gets hotter and hotter because your getting closer to the sun's core which is 15,000,000 F and 13,000,000 C
Where is the Sun's core?
The core just means the centre. Therefore, the core of the Sun is in the centre of the Sun.
Is the Sun's core its hottest point?
the sun's core is the hottest part of the sun
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.
How hot is the core of the sun in kelvin?
The core of the sun is about 15 million Kelvin.
Does the sun and the earth have a hydrogen core?
There's hydrogen at the core of the sun - that's the sun's main fuel - but earth's core is mostly iron and nickel.
Is the inner core hotter than the sun core?
No it is not, however it is similar to that of the sun's surface
What is the center of a sun called?
The Sun's core.
what is hotter earth's core or the sun?

Is the sun or the earths core hotter?
The sun's core is hotter, it is about 30 billion degrees Celsius.
Can you get closer to the sun or the earths core?
You are already closer to the earths core than you will ever be able to get to the sun
How hot can the core of the sun be?
The sun's core can range to a temperature of around 27 million degrees Fahrenheit.
