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.
The instantaneous Earth–Moon distance, or distance to the Moon, is the distance from the center of Earth to the center of the Moon. In contrast, the Lunar distance ( LD or Δ ⊕ L {\textstyle \Delta _{\oplus L}} ), or Earth–Moon characteristic distance , is a unit of measure in astronomy .
The Earth phase, Terra phase, terrestrial phase, or phase of Earth, is the shape of the directly sunlit portion of Earth as viewed from the Moon (or elsewhere extraterrestrially). From the Moon, the Earth phases gradually and cyclically change over the period of a synodic month (about 29.53 days), as the orbital positions of the Moon around ...
The Sun's gravitational effect on the Moon is more than twice that of Earth's on the Moon; consequently, the Moon's trajectory is always convex [25] [26] (as seen when looking Sunward at the entire Sun–Earth–Moon system from a great distance outside Earth–Moon solar orbit), and is nowhere concave (from the same perspective) or looped.
The Artemis program has dealt with numerous delays, and now isn't expected to land humans on the Moon until 2025 or 2026. NASA originally hoped for a lunar landing in 2024. NASA originally hoped ...
The moon’s gravity slightly bent Juice’s path so it received a much larger gravity assist from Earth. The flyby of Earth reduced Juice’s speed by 10,737 miles per hour (4.8 kilometers per ...
Earth will soon have a second moon, but it will be nothing like the one we're accustomed to seeing in the night sky. The new "mini-moon" will be asteroid 2024 PT5, a space rock discovered earlier ...
The Moon is Earth's only natural satellite. It orbits at an average distance of 384,400 km (238,900 mi), about 30 times the diameter of Earth. Tidal forces between Earth and the Moon have synchronized the Moon's orbital period (lunar month) with its rotation period at 29.5 Earth days, causing the same side of the Moon to always face Earth.
