The curvature of the Earth is evident in the horizon across the image, and the bases of the buildings on the far shore are below that horizon and hidden by the sea. The simplest model for the shape of the entire Earth is a sphere. The Earth's radius is the distance from Earth's center to its surface, about 6,371 km (3,959 mi). While "radius ...
Flat Earth is an archaic and scientifically disproven conception of the Earth's shape as a plane or disk. Many ancient cultures subscribed to a flat-Earth cosmography, notably including the cosmology in the ancient Near East. The model has undergone a recent resurgence as a conspiracy theory. [1]

The length of twilight would be very different on a flat Earth. On a round Earth, the atmosphere above the ground is lit for a while before ...
The first images from space were taken on the sub-orbital V-2 rocket flight launched by the US on October 24, 1946. Satellite image of Fortaleza.. Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world.
Pale Blue Dot is a photograph of Earth taken on February 14, 1990, by the Voyager 1 space probe from an unprecedented distance of over 6 billion kilometers (3.7 billion miles, 40.5 AU), as part of that day's Family Portrait series of images of the Solar System.
Contrary to the popular belief that the Earth was generally believed to be flat until a few hundred years ago, the spherical shape of the Earth (and other celestial bodies) has been widely accepted in the Western world (and universally by scholars) since at least the Hellenistic period (323 BCE–31 BCE), with the first known measurement of Earth's circumference conducted by Eratosthenes.

A natural satellite is, in the most common usage, an astronomical body that orbits a planet, dwarf planet, or small Solar System body (or sometimes another natural satellite). Natural satellites are colloquially referred to as moons , a derivation from the Moon of Earth .
