What is an eclipse compared to occultation?

Answer 1

An eclipse is an occultation.

An occultation is when three bodies align so that the middle one passes over the most distant one from the perspective of an observer on the third body.

An eclipse is an occultation of the Moon and the Sun. The difference is that occultations usually involve bodies which are distant and relatively very small. The Sun and the Moon are both large bodies when viewed from the Earth and have about the same angular diameter. This allows solar features such as the corona to become visible during a total eclipse.

An occultation is when one celestial body passes in front of another, obstructing the observer's view from Earth, whereas an eclipse is when one celestial body blocks the light from another celestial body, usually the Sun, Earth, and Moon. The primary distinction between the two events is that an occultation involves obstructing view, whereas an eclipse involves blocking light.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
