Did you observe the total lunar eclipse? It was amazing! What do you say?

I did.

I had 3 thoughts.

1. A lunar eclipse is an eclipse for all inhabitants of the Earth that can observe the Moon at this particular instant. Not true for a solar eclipse.

2. A lunar eclipse happens always upon a full moon.

3. why can we observe a full moon without eclipse? I thought because the sun is huge compared to the size of Earth & Moon.

Because the Moon's orbit around the Earth is inclined 5.1 degrees to the ecliptic. During most full moons, the Moon passes "below" or "above" the Earth's shadow.
