Would you need half a million full moons to equal the brightness of the sun?

The apparent magnitude (AM) [See Link] is a measure of its brightness as seen by an observer on Earth, in the absence of the atmosphere. The brighter the object appears, the lower the value of its magnitude.
The Sun has an AM of -26.73 whereas a full Moon has an AM of -12.6.
The scale is logarithmic: the relative brightness of two objects is determined by the difference of their magnitudes. Pogson's Ratio was suggested in 1856 so that each decrease in magnitude represented a decrease in brightness equal to the fifth-root of 100 (or about 2.512)
So, the difference in magnitude is (-12.6) - (-26.73) giving 14.13
Thus 2.51214.13 = 449,032.
Close enough to half a million.

What is the order of brightness of Jupiters moons from Jupiter?
i believe that it is Io, Europa, Ganymede then Callisto. This is in order of brightness seen from Jupiter's surface.
How do you draw a diagram showing which moon would be brightest from Jupiter?
The four main moons all look about the same brightness as seen from Earth, and they are all at about the same distance from the Earth. That means that their brightness seen from Jupiter would depend on their distances from Jupiter.
How many moons can fit inside a sun?
Both moons and suns, vary so widely in size that it's impossible to answer this. Very roughly a million Earths fit into our sun. The moon is 1/6 the size of Earth. Therefore, 6 million moons fit in the sun,
How would life be if the earth has 2 moons?
we could have a very long nights with two moons together appearing in the sky.and also the scientists would have to go to 2 moons
How many full moons are in 100 years?
That would be 1,200 full moons at a rate of 12 full moons per year.
What is the order of brightness for the Galilean moons?
io Europa ganymede Callisto
What is the order of brightness of Jupiters moons from Jupiter?

When was Ten Million Moons created?
Ten Million Moons was created on 2009-05-19.
How many moons would it take to make the size of the sun?
more than a million
What is the number of moons and satellites on the earth?
40000 million moons and 3000 trillion satilites

How many moons would fit across the Earth?
4 moons would go across the earth, and 109 earths would go across the sun.
What is the moons distance from the sun?
150 million kilometers away from the sun
What type of planet would have the most moons?
A gas giant would have the most moons, seeing as Jupiter has 63 moons, and Saturn has 61 moons, both of which are gas giants.
Do Jupiter's moons orbit it?
Yes. if they did not they would not be Jupiter's moons.
How does the size of a planet seem to be related to the number of moons a planet has?
Larger size seems to equal more moons. Jupiter, Saturn, and Neptune are larger than Mars, and they have many more moons.
