    It is not the case that Planets move around the Sun more slowly than the Sun itself rotates.

    ?Set your confidence on the premises below to see your aggregate.

    Reasons For

    2 perspectives
    Reason for 1 of 2
    ?
    • 1.The Sun's rotational period (~25 days) is faster than Mercury's orbital period (~88 days), but slower than no known planetary orbital period when measured in the same units.
      ?

      Think about whether this reason is strong or weak

    • 2.Kepler's own *Astronomia Nova* data shows all planets take longer to complete one orbit than the Sun takes to complete one rotation, making the claim trivially true but explanatorily vacuous without specifying the causal mechanism.
      ?

      Think about whether this reason is strong or weak

    • 3.A claim that merely redescribes observed regularities without identifying necessary connections between rotation and orbital velocity cannot serve as a genuine causal explanation, as Hume's critique of causal inference demands.
      ?

      Think about whether this reason is strong or weak

    Reason for 2 of 2
    ?
    • 1.Aristotelian physics, which Kepler partially retained, attributes natural circular motion to celestial bodies as their proper form, requiring no external motive power to sustain it.
      ?

      Think about whether this reason is strong or weak

    • 2.If planets possess their own intrinsic principle of circular motion, as Aristotle argued in *De Caelo*, then the Sun's rotation is causally irrelevant to planetary velocity, undermining the supporting argument's causal chain.
      ?

      Think about whether this reason is strong or weak

    • 3.The inference from correlation between solar rotation rate and planetary speeds to a motive emanation is a post hoc fallacy without an independently established transmission mechanism.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Matter possesses an inherent tendency to rest (inclinatio ad quietem).
      ?

      Think about whether this reason is strong or weak

    • 2.This tendency to rest resists the motive power emanating from the Sun.
      ?

      Think about whether this reason is strong or weak

    • 3.Therefore, the actual orbital velocity of a planet is less than what the Sun's motive power alone would produce.
      ?

      Think about whether this reason is strong or weak
