Lunar eclipses happens when Earth comes between the sun and the moon and its shadow is cast on the moon.

However, in partial lunar eclipses, the moon is not completely covered in Earth’s shadow. Partial eclipses occur more frequently than total lunar eclipses.

According NASA, this partial eclipse will last for over 3 hours and 28 minutes. In comparison, the longest total eclipse of the century, which happened in 2018, lasted nearly an hour and 43 minutes.

Unfortunately, the eclipse won’t be visible to sky gazers in Pakistan.

It will be most clearly visible to people watching the sky in the Americas, Australia, Eastern Asia and the Pacific region.

People won’t need any special glasses to view this partial lunar eclipses. It can be seen with a naked eye if you happen to be in the region where the weather is clear and the moon is above the horizon.

This will also be the last lunar eclipses of 2021.
