8.34** Suppose that we decide to send a spacecraft to Neptune, using the simple transfer described in Example 8.6 (page 318). The craft starts in a circular orbit close to the earth (radius 1 AU or astronomical unit) and is to end up in a circular orbit near Neptune (radius about 30 AU). Use Kepler's third law to show that the transfer will take about 31 years. (In practice we can do a lot better than this by arranging that the craft gets a gravitational boost as it passes Jupiter.)

Transcribed Image Text:8.34** Suppose that we decide to send a spacecraft to Neptune, using the simple transfer described in
Example 8.6 (page 318). The craft starts in a circular orbit close to the earth (radius 1 AU or astronomical
unit) and is to end up in a circular orbit near Neptune (radius about 30 AU). Use Kepler's third law to
show that the transfer will take about 31 years. (In practice we can do a lot better than this by arranging
that the craft gets a gravitational boost as it passes Jupiter.)
