Astronomy 101 Exam 1 Questions And
Answers |Latest 2025 | Guaranteed Pass.
What is astronomy? - Answer✔the study of object's and phenomena beyond Earth's
atmosphere [goal: to understand the physics of the Universe]
What is astrology? - Answer✔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? - Answer✔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? - Answer✔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? - Answer✔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? - Answer✔technically the 13
along the celestial equator
What is special about Polaris? - Answer✔this is our modern North Star as it sits very near to
Earth's projected North Pole, [in ~2850 BP N*= Thuban]
constellation - Answer✔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 - Answer✔a pattern of stars not recognized by the International Astronomical Union
as a constellation [ie Big Dipper]
IAU - Answer✔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? - Answer✔No, the pattern will change with
time as stars move
