How significantly does Earth's Planetary Discriminant (Hp) value exceed the minimum threshold of 100?
Answer
Earth's value is over a million, indicating overwhelming mass superiority.
Earth's calculated Planetary Discriminant ($ ext{Hp}$) is approximately 1.7 million, placing it far beyond the minimum requirement of greater than 100 needed for planetary status. This extremely high value demonstrates that over the billions of years of the solar system's evolution, Earth's immense gravitational influence has either accreted or ejected virtually every other significant piece of mass that shared its original orbital path. This massive ratio illustrates the concept of overwhelming mass superiority in its orbital domain.
