Sun Moon Stars

== Sun ==
The sun is "the greater light to rule the day" of Genesis 1. 
Physically its a big ball of mostly hydrogen fusing into helium 149 million kilometers away that provides light in the daytime.
Metaphorically it is a reference to the primary ruler of a nation.  Almost always it is a reference to the king of Israel until Christ is given the designation as the Sun of Righteousness.
== Moon ==
The moon is "the lesser light to rule the night" of Genesis 1.
Physically it is the planet Earth's nearest neighbor between 1/6th and 1/7th the mass of the Earth. It can be seen in day, but typically shines light on the Earth reflected from the sun in the night time.
Metaphorically it is a reference to a secondary authority within a nation. In particular it is a reference to the High Priest of Israel/Judah.
== Stars ==
Stars are also made on the 4th Day of Genesis 1.
Physically they are similar in structure if not in specific mass or exact content as the sun. The closest is Proxima Centauri at a little over 4 light years from Earth.
Metaphorically, stars reference lesser leaders within a government. In particular, they reference the princes of Israel and later the Sanhedrin Council of the Jews.
