Textbook Question
Chapter 2, Problem 52EAP
Flat Earth Society. Believe it or not, there is an organization called the Flat Earth Society Its members hold that Earth is flat and that all indications to the contrary (such as pictures of Earth from space) are fabrications made as part of a conspiracy to hide the truth from the public. Discuss the evidence for a round Earth and how you can check it for yourself. In light of the evidence, is it possible that the Flat Earth Society is correct? Defend your opinion.

- How far (in km) is 3.5 lightyears(ly) – the distance traveled by light in one Earth year?
- How much is this same value in parsecs and (C) in astronomical units (AU)?
Use 299,732 km/s for the speed of light (c) and 1 year = 365 days.
Show your solution and write your answer in both regular notation and scientific notation.
What do we mean by apparent retrograde motion of planets? Why was it difficult for ancient astronomers to explain? How do we explain it today?
Use Kepler's Law, which states that the square of the time, T, required for a planet to orbit the Sun varies directly with the cube of the mean distance, a, that the planet is from the Sun.Using Earth's time of 1 year and a mean distance of 93 million miles, the equation relating T (in years) and a (in million miles) is 804375T2=a3.Use that relation equation to determine the time required for a planet with mean distance of 206 million miles to orbit the Sun. Round to 2 decimal places. years
