When the Earth, Moon and Sun align just correctly, the shadow cast by our planet Earth can fall on the Moon. If the arrangement is flawless, the consequence will be a total lunar eclipse, where the entireness of the Moon arrives the darkest part of the Earth’s shadows. Throughout this time, any place on the surface of Earth that experiences night will be treated to the remarkable show of a wholly dim, red Moon. Total lunar eclipses are comparatively common, on an average, we get to see one every year.
But, something really special is going to happen on the night of January 20th and 21. The entireness of the North and South American continents will get to see the full show of the eclipse. This comprises the partial, penumbral and total stages from everywhere in the Americas. As per the reports, it is the first time this will happen since the year 2000, and it will occur in the year 2058 for the last time. If we see from a scientific position, the way lunar eclipse happen is straight forward. As the Earth is revolving the Sun, a shadow cone is always sprawling the Earth, an area where sunlight cannot be fallen directly since it is hidden due to the presence of our planet Earth.
With a diameter of 12,700 km, which is 8,600 miles revolving at a distance of 150 million km away from the Sun, shadow of Earth spreads for about 1.4 million kilometers. On the other hand, the Moon is just 380,000 km far on average, having a diameter of 3,500 miles. Reportedly, on January 20th and 21, the Moon is going to be at perigee, which is its closest point to Earth. This time, the actual size of the Earth’s shadow, comparative where the moon will be, 3 times larger as relative to the Moon.
