Inside the umbral shadow, the whole of the Sun would be hidden.<\/p><figure class=\"wp-block-image size-full\"><figcaption class=\"wp-element-caption\">Lunar eclipses occur when the Moon passes into the shadow that Earth casts in space. Credit: Pete Lawrence<\/figcaption><\/figure><p>As Earth is a little under four times larger than the Moon, its apparent size from the Moon\u2019s position is approximately four times larger than that of the Sun; remember that from Earth, the Sun and Moon have roughly similar apparent diameters.<\/p><p>As a consequence, Earth\u2019s umbral shadow at the distance of the Moon is also around four times larger than the Moon, depending on where both are in their respective orbits.<\/p><p>On 18 September, the umbral shadow appears roughly 1.7\u00b0 across, the Moon\u2019s apparent diameter around 0.5\u00b0. The penumbral shadow appears 2.6\u00b0 across at this time.<\/p><figure class=\"wp-block-image size-full has-lightbox\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"1023\" src=\"https:\/\/c02.purpledshub.com\/uploads\/sites\/48\/2024\/08\/18-september-lunar-eclipse-chart.jpg\" alt=\"Chart showing the stages of the 18 September 2024 partial lunar eclipse.
