Planetary Uniqueness only bedevils "scientists" because Uniqueness of the Planets would indicate more likely DESIGN rather than the evolutionary planetary formation models because those should produce near complete uniformity...Through faith we understand that the worlds were framed by the word of God,... Hebrews 11:3
"From the 1960s to the 1980s, space probes returned the first close-up
looks at eight of the then-nine planets. To researchers expecting a
simple story that would explain what shaped our solar system, the
observations sent a sobering message: in your dreams.
Today, enigmas
such as Mercury's makeup (mostly iron core, with a thin veneer of rock)
and Uranus's skewed magnetic field continue to bedevil planetary
scientists, and no tidy resolution is in sight."
