Textbook Question
Chapter 1, Problem 6QQ
Choose the best answer to each of the following. Explain your reasoning.
If we represent the solar system on a scale that allows us to walk from the Sun to Pluto in a few minutes, then (a) the planets are the size of basketballs and the nearest stars are a few miles away. (b) the planets are marble size or smaller and the nearest stars are thousands of miles away. (c) the planets are microscopic and the stars are millions of miles away.

Hello, part D was incorrect, and where does the six come from?? I confused on reading the graph
Please answer the following
A) Suppose an object takes 1000 years to orbit the Sun. How many times farther from the Sun is it, when compared with Earth?
B) Communications with the spacecraft Alpha using radio waves require 2000 years for the round trip (there and back). This implies that Alpha is how many light years away from Earth?
Please explain in full detail as I am trying to understand this concept! thank you!
a. Sketch a diagram including Earth, Sun, and Mars, with attention to scale of distance (Mars is about 1.5 AU from the Sun) showing a faster trajectory from Earth to Mars than the minimal energy trajectory discussed in the lecture.
b. Without doing a calculation, how would the arrival velocity of the spacecraft at Mars for the case in (a) compare to the spacecraft arrival in the class example? The lecture example had the spacecraft arriving at Mars with a velocity of 22.49 km/sec.
c. The average velocity of Mars in orbit around the Sun is 24.08 km/sec. Comment on the trade-offs between trajectories, arrival velocities and velocity changes (delta V) required to enter an orbit around Mars.
