Perihelion Day: Earth's Closest Encounter with the Sun in 2024| Oneindia
January 3rd, marks Perihelion Day, signifying Earth's closest proximity to the sun in 2024. Earth approaches within approximately 3 million miles of the sun on this occasion, in contrast to its farthest point, known as aphelion. Unlike fixed annual dates, Perihelion typically occurs about two weeks after the winter solstice, the Northern Hemisphere's shortest day.

00:00 Perihelion Day, observed annually on January 3, carries special significance as it marks
00:08 the closest point of Earth to the Sun in 2024. On this day, Earth approaches the Sun by approximately
00:14 3 million miles, a notable contrast to its farthest point known as Aphelion. The timing
00:20 of the perihelion isn't fixed, but typically occurs about two weeks after the winter solstice,
00:27 marking the shortest day in the Northern Hemisphere. This celestial occurrence highlights the elliptical
00:32 nature of Earth's orbit around the Sun, dispelling the notion of a perfect circle. Presently,
00:37 Earth orbits around 91.4 million miles from the Sun. Research from the University of California,
00:43 Berkeley indicates that sunlight during perihelion is about 7% more intense compared to aphelion.
00:50 Notably, Perihelion Day has gained attention on social media platforms like X, formerly
00:56 known as Twitter. NWS Northern Indiana tweeted, "It's Perihelion Day at this moment in time.
01:03 We are at the point in Earth's orbit that is closest to the Sun, which is about approximately
01:08 91 million miles away." The terms perihelion and aphelion find their roots in Greek, where
01:15 peri signifies "around" and helios refers to the Sun. In the cosmic dance, celestial
01:21 bodies often deviate from perfect circles, adopting elliptical shapes. The diverse orbital
01:26 shapes contribute to the dynamic nature of celestial paths, ranging from slightly elliptical
01:31 orbits to more flattened and highly eccentric paths, showcasing the intricacies of our universe.
