A total lunar eclipse took place on 10 December 2011. It was the second of two total lunar eclipses in 2011, the first having occurred on June 15. A lunar eclipse occurs when the Moon is positioned just right in its orbit to pass through Earth's shadow.

A total solar eclipse took place on Monday, December 14, 2020, when the Moon passed between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. Totality occurred in a narrow path across Earth's surface across parts of the South Pacific Ocean, southern South America, and the South Atlantic Ocean, when the Moon's apparent diameter was larger than the Sun's so all direct sunlight was blocked. The partial solar eclipse was visible over a surrounding region thousands of kilometres wide, including parts of the Pacific Ocean, South America, southwestern Africa, and the Atlantic Ocean. The Moon's apparent diameter was larger than average because the eclipse occurred only 1.8 days after perigee.
