The moon is a satellite. Greeks in the 3rd century BCE noticed the earth's shadow across the moon during lunar eclipses was round, indicating the earth was spherical in shape.
In the 20th century the first artificial satellite, Sputnik, orbited the earth in about 90 minutes.
None. The ozone hole was first observed from Earth's surface.
galileo did because he proved that all the planets revolved around the sun......NOT THE EARTH!!
Man believed Earth to be flat and the stars to be a covering or blanket for Earth.An eclipse was considered to be an omen of either a wonderful event or a terrible disaster.Greek philosopher Pythagoras is accredited as being the first to describe Earth as a sphere during the fifth century BC.
Pythagoras 6th Century BCE.

The concept that the Earth is a sphere dates back to ancient Greece, with philosophers like Pythagoras and Plato suggesting a spherical shape. However, it was Aristotle in the 4th century BCE who provided observational evidence, such as the way ships disappear hull-first over the horizon and the circular shadow of the Earth on the Moon during a lunar eclipse. Later, in the 3rd century BCE, Eratosthenes famously calculated the Earth's circumference using measurements of shadows in different locations.
It's hard to argue it's not a sphere when you've got pictures taken from space showing that it IS a sphere.
Magellan's sailors proved one of Aristotle's theories by circumnavigating the Earth, which demonstrated that the Earth is a sphere. This contradicted the prevailing belief at the time that the Earth was flat.
Yes, artificial satellites can provide evidence that the Earth is a sphere. Satellites orbiting the Earth take images showing its curved surface, and measurements of the Earth's shape can be made based on satellite data. Additionally, the way satellites maintain their orbits around the Earth is consistent with the Earth's spherical shape.
The first man to theorize that the Earth was a sphere was the ancient Greek philosopher Pythagoras in the 6th century BC. He believed that the Earth was round because of its symmetry and harmony with other celestial bodies.
Earth is approximately an oblate spheroid, meaning it is mostly spherical but slightly flattened at the poles and bulging at the equator. It is not a perfect sphere due to its rotation causing a bulging effect at the equator.
I am an artificial intelligence and do not belong to any physical sphere of Earth.
