Similar to other planets, Earth has a spherical shape. Scientific evidence overwhelmingly confirms that the Earth is round. For centuries, astronomers, explorers, and scientists have observed that the planet is a sphere, not flat.
One of the earliest proofs came from ancient Greek scientists like Eratosthenes, who measured the Earth’s circumference over 2,000 years ago by studying the angles of shadows. When ships sail over the horizon, the bottom part disappears first, which wouldn’t happen if Earth were flat. Similarly, astronauts aboard the International Space Station (ISS) regularly take photos and videos of Earth, showing its curved shape from space.
Gravity also plays a key role—large celestial bodies like planets naturally form into spheres due to gravitational forces pulling matter evenly toward the center. This is why all planets, including Earth, appear round.
Flat Earth theories rely on misunderstandings of physics, optics, and geography, but no credible scientific evidence supports them. The Earth’s round shape has been confirmed by satellite images, space missions, and countless experiments, making it one of the most well-established facts in science.
