Take 5 Minutes to See What the Moon Will Do During 2013
This new video shows exactly how the Moon will look to us on Earth during the entire year of 2013. While the Moon always keeps the same face to us, it’s not exactly the same face. Because of the tilt in its axis and shape of its orbit, we see the Moon from slightly different angles over the course of a month, and the year. Normally, we don’t see how the Moon “wobbles” in its orbit or as it moves closer and farther away from Earth. But seeing the entire year compressed down to 5 minutes, we can see the changes in libration, and axis tilt — as well as the most noticeable changes, the Moon’s phases.
In this new video from Goddard’s Scientific Visualization Studio, each frame represents one hour. In addition, as an improvement from their previous Moon visualization , this also shows other relevant information, including Moon orbit position, subearth and subsolar points, distance from the Earth.
