EclipseAn eclipse, possibly.
An eclipse is usually an astronomical phenomenon whereby one object comes between the observer and another object, or casts its shadow so as to conceal another object. For example, a solar eclipse occurs when the moon comes between the observer and the sun. There is no volume to be measured in these circumstances. One possible alternative is that you meant an ellipse. But even that does not work because an ellipse is a 2-dimensional shape and 2-d shapes do not have volumes.
the angle at which a shadow is formed
Well, no trees have a shadow if it is dark, or if they are shaded by a bigger tree. But a family tree may have no shadow.
When the sun is low down, the shadow is longer. If the sun is high up the shadow is shorter.

The effect of a planet or satellite casting a shadow on another is called an eclipse. We see this most often when the earth goes between the moon and the sun. We have solar eclipses where the moon goes between the earth and sun also.

That happens when the satellite enters Earth's shadow.
