    The planets and our moon follow this line approximately and so only occasionally appear very close together. Occultations occur when a big object like say, the moon, moves in front of a smaller appearing object, like a planet. Transits occur when an apparent small thing like a planet moves in front of a big thing, like the sun.
  2. eclipse2017.nasa.gov

    When an apparently small celestial object (like a planet) moves in front of an apparently big one (like the sun), astronomers say that a "transit" has occurred. Transits of Mercury happen around 10 times in a century. The next one will occur on November 11, 2019. Transits of Venus happen twice every 105 or 121.5 years, separated by eight years.
  3. The free, 2D rectilinear short films to be provided through Science through Shadows (STS) are intended to engage library patrons in public awareness about solar and lunar eclipses, stellar occultations, and planetary transits. The videos can be shown with closed-captioning on library kiosks and public service announcement screens.

    Science; Transits and Occultations; Transits and Occultations. Eclipses are a special kind of transit, which is when one astronomical body passes in front of another. Transits were used to calculate the Astronomical Unit, or AU, which is the mean distance between the earth and the sun. Jeremiah Horrocks is the first person we know to estimate ...

    Mar 22, 2024A useful way to organize the Mercury's transits is by grouping them into series where each member is separated by 16,802 days or 46 years (= sum of 13 and 33 years). Transits of Venus are much rarer; only six such events have occurred since the invention of the telescope (1631,1639, 1761,1769, 1874 and 1882) Occultation

    in spite of the eclipses of distant stars, there are two phenomena similar to an eclipse: occultations and transits. OCCULTATIONS. In our Solar System, besides the planets, there are thousands of asteroids, comets, and distant objects beyond the orbit of Neptune called trans Neptunians objects.. The best example and largest one of these objects are Pluto and its moons but there are many others ...

    Eclipses, Transits, and Occultations In this simple guide, David Levy inspires readers to experience the wonder of eclipses and other transient astronomical events for themselves. Covering both solar and lunar eclipses, he gives step-by-step instructions on how to observe and photograph eclipses. As well as explaining the science

    Describes how eclipses, transits and occultations are all interrelated and what we can learn from them; Relates the important discoveries made by observers of these events, ranging from evidence of satellites and asteroids, the dimensions of asteroids, unsuspected rings of planets, the structure of planetary atmospheres and the discovery and makeup of extra solar planets

    When we are fortunate enough to view an exoplanetary system nearly edge-on, the star and planet periodically eclipse each other. Observations of eclipses (transits and occultations) provide a bonanza of information that cannot be obtained from radial-velocity data alone, such as the relative dimensions of the planet and its host star, as well as the orientation of the planet's orbit relative ...
