The Big Dipper

To find the North Star,
imagine a line between
the two stars marking
the front of the cup
- Dubhe and Merak
(aka Alpha and Beta)
- continue that line up
about 5 times its length
points right to Polaris

This Constellation
is known as
The Government
in Chinese Mythology.

These 7 stars are
all of similar makeup
and relatively close to
each other - and to us
- likely a common origin.

To find the Ecliptic
(the orbital plane
of the Solar System),
the curve of the handle
of the Big Dipper "arcs" to
Arcturus (Alpha Bootis) -
continue the same arc to
Spica (Alpha Virginis)
- right on the Ecliptic -
with Blue Regulus
(Alpha Leonis)
to the west
and Red Antares
(Alpha Scorpii)
to the east.
