Earth's seasons are caused by its distance from the Sun.

No original person or first publication responsible for this misconception is established by the cited material. It is reviewed as a general causal assertion, not attributed to a named speaker.

NASA Goddard’s StarChild question “When is Earth closest to the Sun?” (January 2003) explicitly asks whether varying Earth–Sun distance causes seasons and explains why it does not. Read the documented discussion.

NASA’s StarChild explanation identifies the 23.5-degree tilt of Earth’s spin axis as the main cause of seasonal weather patterns. The causal claim being reviewed is that changing distance from the Sun produces the seasons. The source directly contrasts that explanation with axial tilt rather than merely stating that Earth’s orbit is elliptical. [1]

During northern winter, the north pole is tilted away from the Sun and days are shorter. NASA explains that being a little closer to the Sun in January does not make much difference to that seasonal pattern. This is a useful check on the distance explanation: proximity alone would not explain why northern winter occurs near that point in the orbit. [1]

At the same time, the Southern Hemisphere has the opposite seasonal pattern because the south pole is tilted toward the Sun during northern winter. Keeping the hemispheric distinction is essential. “January is winter” is not a globally valid statement, and a source about Northern Hemisphere winter cannot be used as if it describes both hemispheres. [1]

The cited page is a January 2003 educational question with a year-specific perihelion example. We do not turn its exact calendar date into a permanent annual rule. The conclusion is about the principal cause of the seasonal cycle, not a claim that orbital distance has absolutely no effect on the energy Earth receives. [1]

   “Seasonal weather patterns are mostly caused by the 23.5-degree tilt of our planet's spin axis and not by Earth's elliptical orbit.”

   NASA’s educational explanation directly addresses the proposed cause of seasons and contrasts the simultaneous Northern and Southern Hemisphere seasons. Its historical perihelion example is explicitly about 2003.

This is an editorial review of NASA’s educational explanation, not a detailed climate model. The page’s calendar example is historical and its wording is “mostly caused”; the review does not assert that Earth–Sun distance has zero physical effect. The first historical author of the misconception remains unestablished.
