What is astronomy? - =the study of object's and phenomena beyond Earth's atmosphere [goal:
to understand the physics of the Universe]
What is astrology? - =the belief that the position of heavenly bodies, and celestial events
correlate with Earthly events and Human events
How do you determine your astrological sign? - =the position of the Sun in a particular zodiacal
constellation on the day you were born [in ancient Greece] due to procession the signs from
ancient Greece are about 1 sign off. ei If Sun is in Pisces the day you were born, you were
Aquarius in ancient Greece
What is special about the constellations that make up the zodiac? - =these constellations are
defined by the path of the Sun throughout the year [Moon&planets also move through these
constellations]
If the Sun is in Taurus at noon, what constellation will it be in at sunset? - =Taurus [21 days to
touch Gemini's toes]]; 5.8%/365 day orbit. Our perception of the Sun's occupation of a
particular zodiac sign will shift as the Earth progresses in its 365 day orbit around the Sun
How many constellations does the sun move through in a year? - =technically the 13 along the
celestial equator
What is special about Polaris? - =this is our modern North Star as it sits very near to Earth's
projected North Pole, [in ~2850 BP N*= Thuban]
, constellation - =an area of sky containing an accidental pattern of stars named after a person,
animal, or object; helps people locate objects in the sky
asterism - =a pattern of stars not recognized by the International Astronomical Union as a
constellation [ie Big Dipper]
IAU - =International Astronomical Union established 88 constellations with precise boundaries
so that every portion of the sky is contained within a constellation
Are stars within constellations bound by gravity? - =No, the pattern will change with time as
stars move
In Winter the Sun - =rise:South of East ---> set:South of West
In Summer the Sun - =rise: North of East ---> set North of West
On the Equinoxes the Sun - =rise: East ---> set: West
Seasons are caused by - =the tilt of the Earth on it's axis
Summer season - =Sun is in the sky longer, more times to heat up the Earth,
When the Sun is higher - =sunlight hits the surface of more directly and shines more energy
over a smaller area
When the Sun is lower - =sunlight hits the surface at an angle and shines over a a wider area
[with less concentration]
South Pole= - =South Celestial Pole
