The Moon appears to have approximately the same size as the [[Sun]] when viewed from Earth.  This creates a unique symmetry and phenomenal [[solar eclipse|solar eclipses]].

Coincidentally, the Moon is just far enough away from the Earth to appear the same size of the Sun.

===Origin theories===

Most astronomers assert that the Moon originated from a collision early in Earth's history which created an orbiting ring of debris from the [[iron]]-poor surface of the planet which eventually coalesced into the moon.<ref>http://www.astronomy.com/asy/default.aspx?c=a&id=2198</ref> This theory is confirmed by  the relatively low levels of [[iron]] in the Moon's crust.<ref>J. H. Jones: [http://www.lpi.usra.edu/meetings/origin98/pdf/4045.pdf Tests of the Giant Impact Hypothesis]</ref><br />Biblical history records the Moon being created on the fourth day of [[creation week]], along with the Sun.
