This 4K visualization shows the moon's phase and libration at hourly intervals throughout 2017, as viewed from the Northern Hemisphere. Each frame represents one hour. In addition, this visualization shows the moon's orbit position, sub-Earth and subsolar points, distance from the Earth at true scale, and labels of craters near the terminator. Production music provided by Killer Tracks.To learn more about this visualization, or to see what the moon will look like at any hour in 2017, visit our "Dial A-Moon" website: http://svs.gsfc.nasa.gov/4537Credit: NASA's Goddard Space Flight Center/David LaddIf you liked this video, subscribe to the NASA Goddard YouTube channel: http://www.youtube.com/NASAExplorerOr subscribe to NASA’s Goddard Shorts HD Podcast: http://svs.gsfc.nasa.gov/vis/iTunes/f...
