13 gru 2023 · The temperature of the Sun varies, from 5500 C (10,000 F) on its surface up to 15 million C (27 million F) at its core. Have you ever wondered just how hot the Sun is? It’s not a single temperature because the Sun consists of layers where different processes occur.
The Sun is the star at the center of the Solar System. It is a massive, nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies.
Sun’s Central Core Temperature. m = ρAR. F = G(m/2)M/R2. p = F/A = GρM/2R. p/ρ = GM/2R. pV = NkT. p/ρ = kT/mH. GM/2R = kT/mH. T = GmHM/(2kR) T = 1·107 K. (Estimate)
A rough estimate of a body's temperature in the solar system is $$T=\frac{280K}{\sqrt{D_{AU}}}$$ if we calculate the AU fraction from the Sun's "edge" to its center, R over D = $4.65x10^-3$, and substitute this into the formula, the Sun's temperature would be about 4100K.
MEASURING THE TEMPERATURE OF THE SUN. SYNOPSIS: In this lab you will measure the solar flux, the amount of energy per unit area per unit time that reaches the Earth from the Sun.
The core is approximately 20% of the size of the solar interior and is thought to have a temperature of approximately 15 million K, making it the hottest part of the Sun. Above the core is a region known as the radiative zone —named for the primary mode of transporting energy across it.
