Let's review a little. A total lunar eclipse happens when the umbra, which is the Earth casting an opaque shadow on the moon, makes it look red. A partial lunar eclipse is when the moon passes through the penumbra which is when the Earth casts more of a translucent shadow on the moon. A total solar eclipse will cover the whole sun, but a partial solar eclipse will only cover part of the sun. There are so many differences between solar and lunar eclipses. Hopefully now you know them.
