Imagine you are part of a team planning to send an astronaut on a solar system “road trip.” To plan for this
 trip, the astronaut's weight at each destination must be known. On Earth, the astronaut weighs 50 kilograms
 which is 490 Newtons. Using the data from the table, calculate the missing weight values. (The values for
 Earth are already known.) Then plot the gravity of each location—the moon, Mars, Earth, and Venus—versus
 the weight of the astronaut at each location.
