Editing Apparent magnitude (section)

=== Example: Sun and Moon ===
''What is the ratio in brightness between the [[Sun]] and the full [[Moon]]?''

The apparent magnitude of the Sun is −26.832<ref name="IAU2015B2"/> (brighter), and the mean magnitude of the [[full moon]] is −12.74<ref name="moon-fact" /> (dimmer).

Difference in magnitude:
<math display="block"> x = m_1 - m_2 = (-12.74) - (-26.832) = 14.09. </math>

Brightness factor:
<math display="block"> v_b = 10^{0.4 x} = 10^{0.4 \times 14.09} \approx 432\,513. </math>

The Sun appears to be approximately {{val|400000}} times as bright as the full Moon.
