    Did you ever wonder how hot the sun is? On a sunny day, if the temperature rises more than 95 degrees Fahrenheit (35 degrees Celsius) we start feeling hot – and we are at a distance of 149 million kilometers (93 million miles) from the Sun! Which means the Sun would

    actually be a 1000 degrees hot? Oh no, it’s much more than that – the surface temperature of the sun is nearly 10,000 degrees

    Fahrenheit (5538 degrees Celsius)
    ! What does it take to stay that hot? The sun burns up 700 million tons of hydrogen and 695

    million tons of helium in one second
    to create the amount of energy to keep it burning at this temperature.
    35 degrees to 50 degrees

    Celsius we can all tolerate but more than that we cannot tolerate. Which means that had we been any closer to the Sun we would all have burned to death.

    Sun does not burn hydrogen as H2+02 =H20

    Instead two hydrogen atoms fuses together to form Helium.
    Since the mass of one atom of helium formed is slightly less than the total mass of 2 fused hydrogen,
    the excess mass left is turned into energy and radiates out as in E=MC^2
    So if the mass difference is 0.000000001gm,the speed of light = 299 792 458 m / s
    how much energy will be radiated??
    Do the mass E= (1x10^-12 )x(299,792,458)^2

    Nothing is burning in the sun.

    Earth's orbit is elliptical, not a perfect circle, which means that we are not a constant distance from the sun. To say that "had we been any closer to the Sun we would all have burned to death" is a fallacy.
