| How much the moon is dimmed depends on whether it passed through the penumbra or the darkest part of the shadow, the umbra. |
| The total eclipse begins when the Moon is fully inside the umbra, but it won't be completely blacked out. |
| The Moon can then pass through a part of the umbra and then there is a partial eclipse. |
| First, the Earth stopped turning relative to the sun, and the moon parked itself on the dark side, a little outside the umbra. |
| If you were in a spaceship and you passed through the Earth's umbra you would not be able to see any part of the Sun. |
| For an observer standing between the Moon and the umbra cone summit the eclipse is total. |
