which event would be less widely visible from Earth: a partial lunar eclipse or a total lunar eclipse? explain please
adell [148]

Answer:

I had the same question and I put a total lunar eclipse.

Explanation:

A total lunar eclipse would be less widely visible because, in a partial lunar eclipse the moon only has to partly be in the Earth's shadow.

I don't know if this is helpful or not, but this is what I put if you still needed it.
