10 Facts about the Earth

Earth is not a perfect sphere: Earth is often depicted as a perfect sphere, but it's actually an oblate spheroid. This means it bulges slightly at the equator due to the centrifugal force caused by Earth's rotation.
The Earth's core is hotter than the surface of the Sun: The temperature of Earth's inner core is estimated to be around 9,000 to 13,000°F (5,000 to 7,000°C), which is hotter than the surface of the Sun, which is around 10,000°F (5,500°C).
Earth has a "second moon": Earth has a small asteroid, known as 2023 CX1, that orbits the Sun but sometimes gets caught in Earth's gravitational pull, making it temporarily a "second moon." It is too small to be visible to the naked eye and doesn’t remain in orbit for long.
The Earth has a "Magnetic Poles Flip" cycle: Earth's magnetic field is not constant; it flips roughly every 200,000 to 300,000 years. This means the North and South Magnetic Poles switch places, which has happened many times in Earth's history.
Earth's oceans are deeper than its highest mountains: The Mariana Trench in the Pacific Ocean is the deepest part of Earth's oceans, reaching depths of about 36,000 feet (11,000 meters), which is deeper than Mount Everest, the highest point on Earth, which stands at 29,032 feet (8,849 meters).
Earth's atmosphere extends far beyond the Moon's orbit: Earth's atmosphere doesn't just stop at the edge of space. In fact, the atmosphere gradually transitions into the exosphere and extends as far as 10,000 kilometers (6,200 miles) above Earth's surface, well beyond the Moon’s orbit.
The Earth is slowing down: Earth's rotation is gradually slowing down due to tidal friction caused by the gravitational interaction between Earth and the Moon. This is causing the length of a day to increase by about 1.7 milliseconds per century.
More than 80% of Earth's ocean is unexplored: Despite covering 71% of the Earth's surface, the majority of the ocean remains unexplored. Scientists estimate that less than 20% of the ocean has been mapped or studied in detail.
Earth's crust is made up of floating tectonic plates: Earth's outer layer, the lithosphere, is broken up into large pieces called tectonic plates. These plates are floating on the semi-fluid asthenosphere beneath them, and their movement causes earthquakes, volcanic eruptions, and mountain formation.
Earth's atmosphere is 100 times thinner than a sheet of paper: Though Earth’s atmosphere may seem substantial, it is incredibly thin when compared to the size of the planet. If Earth's atmosphere were scaled to the size of a sheet of paper, it would be only about 100 times thicker than that sheet.
