Which of these stars has the largest mass?
The largest known star is UY Scuti, a hypergiant with a radius somewhere around 1,700 times larger than the sun. Its mass, however, is only 30 times that of our nearest star. If R136a1 swapped places with the sun, it would outshine our closest star as much as the sun currently outshines the moon.

What was the core temperature of the Sun?
– Astronomy Stack Exchange It was estimated that the heat inside the core of the Sun inside around 15 000 000 °C – this value is extremely enormous. How did scientists estimate this value?
What’s the best way to estimate the central temperature?
Use the equation of state (the ideal gas law) to estimate the central temperature: Make assumptions: constant density 100% hydrogen gas and we get which, actually isn’t too bad. The actual “best” value is more like 15 million K.
How are the internal properties of the sun determined?
Making several assumptions, e.g., that the Sun behaves as a fluid and that local thermodynamic equilibrium applies, the stellar equations of state can be used. Numerical methods are applied to these equations to determine the internal properties of the Sun, such as its central temperature.
What happens at the center of the Sun?
They are cooler than their surroundings. At the center of the Sun, fusion converts hydrogen into? Helium, energy and neutrinos. Solar energy leaves the core of the Sun in the form of what?
