15 If it is really between the earth and the sun it is called a "solar eclipse" and and the moon's shadow falls on the earth at certain places, because it is not large enough to cover the whole sun except on a shadow path. A total solar eclipse occurs when the Moon completely covers the Sun's disk, as seen in this 1999 solar eclipse.
Why can we see the moon when it is between the Earth and the Sun?

Now the Sun isn't spherical, and it is rotating, but it isn't very aspherical and it isn't rotating very fast so to a good approximation our equation (1) will describe the spacetime curvature around it. In fact equation (1) is the equation used by Einstein when he achieved one of GR's first triumphs by calculating the perihelion shift of Mercury.
The light from the Sun has a color blip, right where early atomic physics suggested the element with two protons in its nucleus would radiate. That element, called Helium (from Helios, Greek word for the Sun) really does exist. discovery of Helium There isn't any of it (nor evidence of it) in light from a typical light bulb.
Is the light from the Sun the same as the light from a bulb?
The Sun and Moon seem to have the same size because of this amazing coincidence: the moon is 400 times smaller than the Sun and 400 closer than the Sun. Checking 400 from this source:

Besides the moon, the sun has a tidal component for the earths oceans, and when that crashes into continents the energy absorbed comes from the potential energy of the sun-earth system. I am not sure how this compares to the distance loss due to the mass and energy radiation of the sun you mentioned.
