• I said that if a planet were 3 AU from the
  Sun, its sidereal period would be 9 years.
  Sidereal period is defined in the activity on
  page 61 and Mars' sideral period is given as 1.88
  years. I can't find any discussion of sidereal
  period in the reading. Mar's period of
  revolution is 1.881 in the chart on p. 57, so I
  thought they were the same.

• On page 68, the text states that Galileo
  published in Italian, a language common people
  were more likely to read than Latin, and the
  resulting controversy was a factor in the
  churches issuing a proclamation prohibiting
  Galileo from holding or defending his views.
