Understanding the Answer
Let's break down why this is correct
Answer
During a lunar eclipse the Moon first moves into the Earth's umbral shadow, marking the start of the eclipse. As it travels deeper, the shadow’s edge (penumbra) gradually covers the Moon, turning it slightly darker. When the Moon reaches the center of the shadow, it becomes fully engulfed, often turning a reddish color because Earth's atmosphere bends some sunlight. The Moon then exits the shadow, brightening again as it leaves the penumbra, and finally disappears from the shadow entirely, ending the eclipse. For example, a total lunar eclipse lasts about 2–3 hours from first contact to the final exit.
Detailed Explanation
The Moon first enters the penumbra, where it starts to look slightly darker. Other options are incorrect because This answer flips the order; It starts with exiting the penumbra, which cannot happen first.
