...college professors agreed last night that Kuiper's claim is a perfectly possible one, but both felt that it would be quite difficult to prove...
...Kuiper has said in an interview, "The heavenly body we know as Pluto is in reality only one of Neptune's satellites that broke way untold millions of years...
...comparing the photographs of faintly banded Venus with parallel lines drawn around a white globe, Dr. Kuiper decided where the Venusian equator must be. This told him the position of the poles and the axis of rotation that passes through them. The axis, he decided, is inclined about 32° from the plane of the ecliptic in which the planets revolve around the sun. Since the earth's inclination is only about 23½°, the seasonal changes of climate on Venus, due to the changing angle of sunlight, may be considerably more pronounced than they are on earth...
...whole, Dr. Kuiper concluded, the meteorology of waterless Venus must be rather simple. There are no ocean basins to complicate the circulation of the dusty carbon-dioxide winds. The yellow dust merely drifts along; it does not condense unpredictably and fall as capricious rain to confound meteorologists...
