Nguyệt thực kéo dài trong bao lâu?

Nguyệt thực kéo dài trong vài giờ, trong khi nhật thực toàn phần chỉ kéo dài trong vài phút tại bất kỳ vị trí nào do kích thước nhỏ hơn của bóng của Mặt trăng.

Không giống như nhật thực, nguyệt thực chỉ có thể quan sát một cách an toàn bằng mắt thường vì hình ảnh nguyệt thực mờ hơn so với hình ảnh mặt trăng đầy đủ.

Thời gian tối đa của nguyệt thực toàn phần: 104 phút (trường hợp thường hay tái diễn); nguyệt thực một phần: 6 giờ.
