[Answer] Astronomical distance crossword clue

• Astronomical distanceDistance measures in cosmology' explains in detail how to calculate the different distance measures as a function of world model and redshift. iCosmos: Cosmology Calculator (With Graph Generation ) calculates the different distance measures as a function of cosmological model and redshift, and generates plots for the model from redshift 0 to 20.The unit (symbol: au, ua, or AU) is a unit of length, roughly the distance from Earth to the Sun and equal to about 150 million kilometres (93 million miles). However, that distance varies as Earth orbits the Sun, from a maximum to a minimum and back again once a year.Originally conceived as the average of Earth's aphelion and perihelion, since 2012 it has been defined as exactly ...
  
  A particularly important early development was the beginning of mathematical and scientific astronomy, which began among the Babylonians, who laid the foundations for the later traditions that developed in many other civilizations. The Babylonians discovered that lunar eclipses recurred in a repeating cycle known as a saros.The is now as exactly 149 597 870 700 meters. It is approximately equal to the mean Earth–.The cosmic distance ladder (also known as the extragalactic distance scale) is the succession of methods by which astronomers determine the distances to celestial objects. A real direct distance measurement of an
