As astronomers measure distances, this is a cat's-whisker miss. The earth's gravitational pull would capture thousands, perhaps millions, of meteors: small bits of straggling comet stuff. When they plunged into the atmosphere at thousands of miles per hour and turned into incandescent gas, the show would be the best since...
...clear the earth with speed to spare, says Professor Herrick, a space ship should start at 8 miles per second. Once clear, it becomes a miniature planet with an orbit of its own. The gravitation fields of surrounding bodies pull it hither & yon. By taking advantage of these pulls, the space navigator can guide his ship...
keep the glider in the earth's orbit, so the great pull of the sun would make it spiral inward toward the orbit of Venus...
...planning any voyage, the space navigator would have to allow for a host of "perturbations." Distant objects such as Neptune or comparatively small objects such as the moon might pull the ship off its course. A round-trip voyage would be ticklish. The ship would have to circle the objective planet and come back just in time to meet the earth. A miss would mean a plunge toward...
