- Pythagoras, a Greek mathematician and philosopher, provided some of the earliest known evidence that the Earth was round through mathematical reasoning in the 6th century BCE.
- Aristotle, a Greek philosopher, observed during the 4th century BCE that the Earth cast a round shadow on the Moon during a lunar eclipse, indicating a spherical shape.
- Ferdinand Magellan's circumnavigation of the globe in the 16th century provided concrete evidence that the Earth was round and not flat.

What is the shape of planet earth is it a hemisphere a hemicube a circle or a sphere?
Planet Earth is best described as a sphere. While it is not a perfect sphere due to its rotation causing a slight bulge around the equator, it is most accurately represented by a three-dimensional shape that is perfectly round in all directions.
What object is closest to the earth in all three system?
The International Space Station (ISS) is the object closest to the Earth in all three systems: Earth-centered, Earth-fixed, and Earth-bound.
Is the moon flat?
No, the moon is not flat. It is a three-dimensional celestial body that orbits Earth. Its spherical shape is a result of its gravitational pull, much like other celestial objects in space.
The first people to leave Earth's Orbits?
The first people to leave Earth's orbit were the crew of Apollo 8 in 1968. They became the first humans to travel beyond Earth's orbit, orbiting the Moon before returning safely to Earth.
What objects is closest to earth in all three systems?
the moon is the closest to the earth
Who led A three year expedition that proved the earth is round?
The Chinese admiral, Zheng He, in 1421. Ancient maps produced by his captains appear to have found their way to Portugal and later to Spain.
Round three-dimentional object the shape of the earth?
a planet
Who led a three-year expedition that proved the earth was round?
Vasco da Gama led the first around-the-world expedition, but NOT to prove that the world was round. That had already been widely known for well over 1,500 years. The ancient Greeks had even very accurately calculated the exact size of planet Earth and they even had worked out (to the exact number of degrees) the slight tilt that the axis of our planet has.
How long does it take a spaceshuttle to go a round earth three times?
52 years
How many people in Spain own a computer?
round about three million
What is the round model of earth?
The round model of the Earth is known as a sphere. It is a three-dimensional shape where all points on the surface are equidistant from the center, giving it a circular appearance in all directions. The spherical shape of the Earth is a fundamental concept in geography and astronomy.
A round model of the earth is called?
A round model of the Earth is called a globe. It is a three-dimensional representation of the Earth's surface, showing countries, continents, oceans, and other geographical features in their accurate shapes and proportions.
What is a flat map called that represents a portion of the round earth?
A flat map that represents a portion of the round earth is called a "map projection". Map projections are used to display the three-dimensional earth on a two-dimensional surface, like a paper map.
Is earth round or has flat surfaces up and down?
Earth is not completely flat, nor does it have sharp edges. It is a three-dimensional shape with a slightly flattened sphere-like structure, often described as an oblate spheroid because it bulges slightly at the equator and flattens at the poles.
What three contests does prince triumphs in?
The Three contests were an Archey round, Swordsmanship round, and a horse round
How many names of people are on earth?
Three To Four Billion, i Believe.
What concept was missing in people's minds in the 16th century when they couldn't believe Earth was moving?
At that time the Earth did not seem to move and there was no reason to think that it did. But Johannes Kepler produced a new and radical model of the solar system in 1609 which used the idea that the Sun is at the centre with the Earth in orbit round it. Copernicus had produced an earlier model which also had the Sun at the centre. Newton's discoveries in dynamics and mathematics, and the law of gravity, led to a new understanding of how the planets moved under the inverse-square law of gravity. He proved that the planets must move in elliptical orbits following Kepler's three laws of planetary motion. That work was published in 1687 and since then no-one has found any appreciable flaws in the theory, so we have all been forced to the conclusion that the Earth must be in orbit round the Sun.
