The Blue Marble is a photograph of Earth taken on December 7, 1972, from a distance of around 29,400 km (18,300 mi) from Earth's surface.. The original image (NASA designation AS17-148-22727) was taken by either Ron Evans or Harrison Schmitt of the crew of the Apollo 17 spacecraft on its way to the Moon, and showed Earth with the South Pole facing upwards; since then, a cropped and rotated ...
Earth is rounded into an ellipsoid with a circumference of about 40,000 km. It is the densest planet in the Solar System. Of the four rocky planets, it is the largest and most massive. Earth is about eight light-minutes away from the Sun and orbits it, taking a year (about 365.25 days) to complete one revolution.
Owner. NASA. Pale Blue Dot is a photograph of Earth taken on February 14, 1990, by the Voyager 1 space probe from an unprecedented distance of approximately 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 . In the photograph, Earth's apparent size is less than a ...
Earthrise, taken on December 24, 1968, by Apollo 8 astronaut William Anders. Earthrise is a photograph of Earth and part of the Moon 's surface that was taken from lunar orbit by astronaut William Anders on December 24, 1968, during the Apollo 8 mission. [1] [2] [3] Nature photographer Galen Rowell described it as "the most influential ...
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 ...

Sensors on Earth observation satellites often take measurements of emitted energy over some portion of the electromagnetic spectrum (e.g., UV, visible, infrared, microwave, or radio). [ 1 ] The invention of climate research through the use of satellite remote telemetry began in the 1960s through development of space probes to study other planets.
List of directly imaged exoplanets. Motion interpolation of seven images of the HR 8799 system taken from the W. M. Keck Observatory over seven years, featuring four exoplanets. This is a list of extrasolar planets that have been directly observed, sorted by observed separations. This method works best for young planets that emit infrared light ...
