Of course it is gravity attaching the earth to the sun.

It does NOT matter the speed of gravity, and there is NO way to measure it from that relationship, because the earth is ALWAYS at a set distant. Therefore measuring the speed of gravity from it is useless, because there is NO change to measure, the earth is at a set distance and will reamin there.

"Of course it is gravity attaching the earth to the sun."

And if this force were to be disturbed, say by an object such as the Moon coming in between the Sun and Earth, or by moving the Earth further away from the Sun, or by dispersing the Sun's atoms in all directions, or by whatever means of disturbance that you choose to agree upon, would said disturbance in Gravity be felt *instantly* on the Earth and Sun, or would there be some time delay?
