The Moon is Earth’s only natural satellite and the fifth largest moon in the solar system. It is about 240,000 miles (385,000km) and its gravity helps stabilise our planet’s wobble, which helps stabilise our climate.

It is the brightest and largest object in our night sky. The Earth and Moon are tidally-locked. Their rotations are so in sync we only see one side of the Moon all the time. The moon’s gravity pulls at the Earth, causing predictable rises and falls in sea levels known as tides. To a much smaller extent, tides also occur in lakes, the atmosphere, and within Earth’s crust.

The rhythm of the moon’s phases has guided humanity for millennia, and it passes through each star constellation during its 29-day orbit.

The Moon in Astrology

The Moon represents our subconscious world, our emotions, heart, and the love we are capable to feel in this lifetime. It is the support of our family and in the practical sense and our interpretations, we will see it as a feminine parallel to the Sun.

In Astrology, the Moon is the ruler of Cancer. The Moon represents our deepest personal needs, our basic habits and reactions, and our unconscious. The Moon is associated with the mother and with feminine energy in general. The Moon is both our inner child and our inner mother.

For some of us, our Moons seem to drive our personalities more than the Sun does. This is particularly true if the Moon is in a water sign (Cancer, Scorpio, or Pisces), or if it is conjunct an angle in the chart (near the Ascendant, Descendant, 4th house cusp, or 10th house cusp).

The Moon in Mythology

The moon’s waxing and waning have made it a symbol of time, change, and repetitive cycles around the world. One such cycle is the constant alternation of birth and death, creation and destruction. The Moon is often female, a goddess who may be paired with a sun god. The Greeks associated the moon with the goddess Artemis, sister of Apollo, whereas the Roman name for the moon was Luna, giving us the term “Lunar”.

According to the Greek myth of Endymion and Selene, the moon (Selene) fell in love with a handsome young king named Endymion and bore him 50 daughters. One version of the story says that Selene placed Endymion in eternal sleep to prevent him from dying and to keep him forever beautiful.
