The Planets align

On February 26th, in the year 1953 BCE, the tightest conjunction of planets ever witnessed by civilization happened. Mercury, Venus, Mars, and Saturn could be seen inside a circle with the same area as a pea held at arms length, while Jupiter was only a cherry's diameter away. This is suspected to be the beginning of the Chinese calendar.
