Aristarchus’ Conclusions
Diameter of Moon = 1/3 Diameter of Earth
Modern result: closer to 1/4
Truly an achievement in 3rd Century B. C. !
- Also Aristarchus found s = 20 m, so s = 7e
- So sun’s VOLUME is 7 x 7 x 7= 350 times Earth’s!
- Not bad, but Sun is really much farther and much bigger (s=110 e).
- Is this little Earth the center of the Universe?
- How many Earth’s would fit in Sun?
