The Moon is even closer to us than the Sun, but we see it because it reflects the light from the Sun to us, so across the electromagnetic spectrum it's a lot fainter (in visible light, the Sun is roughly 200,000 times brighter than the Moon). But if you look in gamma rays, that changes.View full answer
Keeping this in mind, Is the sun brighter than the Moon?
At these energies, the Moon is actually brighter than the Sun. Brighter colors indicate greater numbers of gamma rays. ... While the Moon's gamma-ray glow is surprising and impressive, the Sun does shine brighter in gamma rays with energies higher than 1 billion electron volts.
Moreover, How much brighter is the sun than the Moon?. The full moon shines with a magnitude of -12.7, but the sun is 14 magnitudes brighter, at -26.7. The ratio of brightness of the sun versus the moon amounts to a difference of 398,110 to 1. So that's how many full moons you would need to equal the brightness of the sun.
Herein, What shines brighter than the Moon?
In turn, these powerful cosmic rays strike the dense part of the Sun's atmosphere and create very powerful gamma rays. So the Sun is actually brighter in gamma rays above 1 billion electron volts than the Moon is.
Why moon is not bright as sun?
But did you know that the moon would also be just another dull orb if not for the sun's rays? The moon shines because its surface reflects light from the sun. And despite the fact that it sometimes seems to shine very brightly, the moon reflects only between 3 and 12 percent of the sunlight that hits it.
When the Earth (and therefore the Moon) is at its perihelion, the closest point in its orbit to the Sun, the sunlight that reflects off the Moon is slightly more intense, causing the full moon's brightness to increase by about 4%, which is imperceptible by the human eye.
Unlike a lamp or our sun, the moon doesn't produce its own light. Moonlight is actually sunlight that shines on the moon and bounces off. The light reflects off old volcanoes, craters, and lava flows on the moon's surface.
It looks so much bigger than everything else in the night sky because it's near us, and so bright because it's reflecting light from the Sun. But the Moon is moving away from Earth at almost 4cm per year.
The Moon is currently in the constellation of Sagittarius.
"These data show us that the Sun is not getting brighter with time. The brightness does follow the sunspot cycle, but the level of solar activity has been decreasing the last 35 years. ... Perhaps the upcoming solar minimum in 2020 will help answer that question."

- There is water on the Moon!
What is most widely accepted today is the giant-impact theory. It proposes that the Moon formed during a collision between the Earth and another small planet, about the size of Mars. The debris from this impact collected in an orbit around Earth to form the Moon.
If 0.3 lumen/m2 is detected at the Earth-Moon distance, then surface of the Moon should be at 0.3 x (384,0000/1738)2 = 48816 lumens/m2. Which equals 282 lumens total over the surface of our bulb. This is works out to a 20 watt incandescent bulb.
According to this scale, full moon has an apparent magnitude of -12.6, whereas Sirius , the brightest star in the night sky, has an apparent magnitude of only -1.46. That is, the moon is more than 28,000 times brighter than the brightest star in the night sky.
What makes the sun so bright is its power source: a process called nuclear fusion, which yields abundant energy. The fusion reaction, along with the sun's enormous size, means it will continue to shine brightly billions of years into the future.
The Moon's current phase for today and tonight is a Waning Gibbous Phase. This is the first phase after the Full Moon occurs. It lasts roughly 7 days with the Moon's illumination growing smaller each day until the Moon becomes a Last Quarter Moon with an illumination of 50%.
July's full moon, also known by other nicknames according to different cultures including Hay Moon, Mead Moon, Rose Moon, Elk Moon and Summer Moon, reached its peak on Friday, July 23. ... Its best-known name, Buck Moon, relates to the fact that the antlers of male deer reach their peak of growth around this time in July.
The Sun is the brightest star as viewed from Earth, at −26.74 mag. The second brightest is Sirius at −1.46 mag.
Tonight's moon is also a supermoon, a full moon or new moon that coincides with the moon's closest position to Earth, making the celestial body appear larger and brighter, according to NASA. The strawberry moon rose Thursday morning and will last into early Sunday morning, according to NASA.
1, 2000, on areas of the moon's surface at both poles (between 85 and 90 degrees latitude). The area with the highest incidence of sunlight was 89% at the north pole, followed by 86% at the south pole, equating to 324 and 314 days of sunlight a year, respectively.
The only significant weather phenomena on Mars are dust storms and strong winds. These dust storms can obscure the sun for very long periods of time, sometimes exceeding several weeks. ... At local noon on Mars, with Sun directly overhead, the solar irradiance is 590W/m2 (590 watts per square metre).
When the Moon is low in the sky, you're seeing its light go through the most atmosphere. Light on the blue end of the spectrum is scattered away, while the red light isn't scattered. ... During the day, the Moon has to compete with sunlight, which is also being scattered by the atmosphere, so it looks white.
