"The Sun's color is white, although from the surface ************SPAM/BANNEAR************ the Earth it may appear yellow because ************SPAM/BANNEAR************
atmospheric scattering ************SPAM/BANNEAR************ blue light.
[12][13] Its
stellar classification, based on spectral class, is
G2V, and is informally designated a
yellow star, because its visible radiation is most intense in the yellow-green portion ************SPAM/BANNEAR************ the spectrum.
[13] In this spectral class label,
G2 indicates its
surface temperature ************SPAM/BANNEAR************ approximately 5778 K (5500 °C), and
V (
Roman five) indicates that
the Sun, like most stars, is a main sequence star, and thus generates its energy by nuclear fusion ************SPAM/BANNEAR************ hydrogen nuclei into helium. In its core, the Sun fuses 430–600 million tons ************SPAM/BANNEAR************ hydrogen each second."
