  • Effects of the Moon on the Earth in the Past, Present, and Future
    Effects of the Moon on the Earth in the Past, Present, and Future Rina Rast*, Sarah Finney, Lucas Cheng, Joland Schmidt, Kessa Gerein, & Alexandra Miller† Abstract The Moon has fascinated human civilization for millennia. Exploration of the lunar surface played a pioneering role in space exploration, epitomizing the heights to which modern science could bring mankind. In the decades since then, human interest in the Moon has dwindled. Despite this fact, the Moon continues to affect the Earth in ways that seldom receive adequate recognition. This paper examines the ways in which our natural satellite is responsible for the tides, and also produces a stabilizing effect on Earth’s rotational axis. In addition, phenomena such as lunar phases, eclipses and lunar libration will be explained. While investigating the Moon’s effects on the Earth in the past and present, it is hoped that human interest in it will be revitalized as it continues to shape life on our blue planet. Keywords: Moon, Earth, tides, Earth’s axis, lunar phases, eclipses, seasons, lunar libration Introduction lunar phases, eclipses and libration. In recognizing and propagating these effects, the goal of this study is to rekindle the fascination humans once held for the Moon Decades have come and gone since humans’ fascination and space exploration in general. with the Moon galvanized exploration of the galaxy and observation of distant stars. During the Space Race of the 1950s and 1960s, nations strived and succeeded in reaching Four Prominent Lunar Effects on Earth Earth’s natural satellite to propel mankind to new heights. Although this interest has dwindled and humans have Effect on Oceans and Tides largely distanced themselves from the Moon’s relevance, its effects on Earth remain as far-reaching as ever.

  • Shepherd Moon Face-Off! 21 December 2012, by Jason Major
    Shepherd Moon face-off! 21 December 2012, by Jason Major Here's Pandora, as seen by Cassini on September 5, 2005: False-color image of Pandora. Credit: NASA/JPL/SSI Raw Cassini image acquired on Dec. 18, 2012. Credit: NASA/JPL/SSI …and here's Prometheus, seen during a close pass in 2010 and color-calibrated by Gordan Ugarkovic: Two of Saturn's shepherd moons face off across the icy strand of the F ring in this image, acquired by the Cassini spacecraft on December 18, 2012. In the left corner is Pandora, external shepherd of the ropy ring, and in the right is Prometheus, whose gravity is responsible for the subtle tug on the wispy ring material. (Please don't blame the moon for any recent unsatisfying sci-fi films of the same name. There's no relation, we promise.) Similar in size (Pandora is 110 x 88 x 62 km, Prometheus 148 x 100 x 68 km) both moons are porous, icy, potato-shaped bodies covered in craters—although Prometheus' surface is somewhat smoother in appearance than Pandora's, perhaps due to the gradual buildup of infalling material from the F ring. Check out some much closer images of these two moons below, acquired during earlier flybys: 1 / 2 Prometheus casting a shadow through F ring haze. Credit: NASA/JPL/SSI/Gordan Ugarvovic The external edge of the A ring with the thin Keeler gap and the wider Encke gap can be seen at the right of the top image. Both of these gaps also harbor their own shepherd moons—Daphnis and Pan, respectively.

Here, we examine retrograde-rotating planets on eccentric orbits and find a previously unknown secular spin–orbit resonance that can drive significant obliquity variations. This resonance occurs when the frequency of the planet’s rotation axis precession becomes commensurate with an orbital eigenfrequency of the planetary system. The planet’s eccentricity enables a participating orbital frequency through an interaction in which the apsidal precession of the planet’s orbit causes a cyclic nutation of the planet’s orbital angular momentum vector. The resulting orbital frequency follows the relationship f =-W2v , where v and W are the rates of the planet’s changing longitude of periapsis and longitude of ascending node, respectively.
