1. Astronomy
I. Definition
SO
i. Astronomy loosely translated means “patterns among the stars” (MC: 1)
II. Your Place in the Universe
i. Your address: street, city, town, country, Earth, Sun, Milky Way, Local Group, Virgo Supercluster,
universe (MC: 3, SA: 1)
LU
ii. Solar System: classical versus dwarf planets (TF: 1, 2, MC: 1–4, 7, SA: 2)
iii. Milky Way: contains 200 to 400 billion stars (MC: 3, 5–7)
iv. Local Group (MC: 3, 8)
TI
v. Virgo Supercluster (TF: 3, MC: 3)
vi. Universe: contains hundreds of billions of galaxies, roughly as many stars as in the Milky Way (TF:
O
4)
vii. Much of the universe is made of dark matter, and all of space is permeated by dark energy (TF: 5,
N
MC: 9, 10)
III. Scale of the Universe
S
i. Speed of light, c 3 108 m/s (MC: 11)
ii. d v t (TF: 2, MC: 12–17)
iii. Light year is a measure of distance (TF: 6, MC: 12, SA: 3)
iv. Distance versus time comparison: circumference of the Earth versus snapping your fingers (MC: 19,
20, SA: 4–6)
IV. Origin and Evolution of Universe
