Astro-

Our Solar System is mostly empty Space, with sparse Matter scattered about, including Sun ☼, Earth ⊕, Moon ☾, the planets ☿♀⊕♂♃♄♅♆♇ & beyond — each massive sphere forms a Time-clock as it majestically moves through Space. Hidden cyclical patterns haved emerged after lifetimes of people observing, recording and theorizing about the motions of the glowing dots in the nighttime sky. The starry sky is fully mapped by the current 88 constellations as outlined in 1930, including the 12 astrological zodiac constellations a, b, c, d, e, f, g, h, i, j, k, l.

Astronomical Unit (au)

One astronomical unit (1 au) is the "average" straight-line distance between the center-of-the-Earth and the center-of-the-Sun, and a convenient Solar System distance scale. Numerically, 1 au is a distance of approximately 150 billion meters (93 million miles) -- with an exact nominal value of 149,597,870,700 meters as defined by the International Astronomical Union's Resolution B2 (2012). The actual Sun-Earth distance varies between 0.9833 au and 1.0167 au throughout the year due to Earth's oval orbit. The Sun is exactly 1 au distant only twice/year about April 4 and October 5 (a few weeks after the spring and autumn equinoxes). Read more
