Total Eclipse

The place to kick back and talk about anything astronomy related that doesn't fit into other categories.

Total Eclipse

The following quotation was taken from this link https://sciencing.com/darkest-portion-m ... -3210.html

'Solar eclipses are so spectacular on Earth because the apparent sizes of the moon and sun are the same. This is a happy coincidence -- the sun is 400 times larger than the moon and just happens to be 400 times farther away. Because the sun is so much larger than the moon, however, the moon's shadow appears much smaller on Earth that the moon itself. That's because sunlight is impinging at an angle from the much larger disk of the sun. The umbra forms a cone that narrows to a width of 100 miles by the time it reaches Earth'

We are told that because sun is 93 million miles away that the sun's rays can be considered parallel. If this is the case then why, in the quote above, does it say the moon's shadow is only about 100 miles when the moon's diameter, we are told, is 2,159 miles?

According to the quote above there is an angle between the sun's diameter and the moon's diameter because the sun is much larger! Something is wrong here.
