Discussion Overview

The discussion revolves around the factors that could potentially increase the frequency of solar eclipses, particularly total solar eclipses, if hypothetical changes could be made to celestial mechanics. Participants explore various ideas related to the Moon's size, orbit, and positioning, as well as practical considerations regarding eclipse visibility.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests decreasing the Moon's size and orbit or stabilizing its wobble to increase eclipse frequency without affecting gravitational effects on Earth.
  • Another points out that the average occurrence of total solar eclipses is about once every four centuries, with geographical location influencing visibility, particularly near the equator.
  • A different viewpoint proposes moving the Moon's orbit closer to the ecliptic plane to achieve monthly eclipses, though this may have implications for tides.
  • One participant humorously notes that rather than altering celestial mechanics, booking flights to view eclipses could increase personal opportunities to experience them.
  • A participant inquires about the typical surface area of totality during an eclipse and its relation to Earth's total surface area, noting that total solar eclipses occur approximately every 18 months, often over oceans.
  • Another participant emphasizes that calculating the odds of experiencing a total solar eclipse is complex and depends on factors like latitude and time of day.

Areas of Agreement / Disagreement

Participants express a range of ideas and hypotheses regarding the frequency of solar eclipses, with no consensus reached on the best approach or solution. The discussion includes both serious proposals and lighthearted remarks, indicating a mix of perspectives.

Contextual Notes

Some claims about eclipse frequency and visibility are dependent on geographical and temporal factors, which are not fully resolved in the discussion.

TL;DR
Hypothetically how can solar eclipses be increased?
I'm near Buffalo and our last total solar eclipse was in 1925 and it looks like the one tomorrow will also be cloudy. What could increase the frequency if we could play god? Decrease the moon's size and orbit, stabilize its wobble in its orbit, etc? Without affecting the gravity effects on earth is there anyway to increase the frequency in most cities to once every 25 years? I don't know if Buffalo gets another on this side of a millennium.
 
Astronomy news on Phys.org
Once in a 100 years is ”lucky”. The world average is a total eclipse around once every four centuries.

If you move closer to the equator you may somewhat increase the rate as the ”risk” of an eclipse being annular would decrease (closer to the Moon).

Move the Moon's orbit so it lies very nearly in the ecliptic plane. You get monthly eclipses, with totality wandering a little. It probably affects tides, but I don't think you get anything too severe.

Just a remark: sometime along the boom of low cost airlines there was a remarkable increase in the frequency of news about expected faraway eclipses.
So - no need to play god: you can just book a flight, as soon as the book for the date is open :wink:

Does anyone know the typical surface of totality during an eclipse? I want to figure how much that compares to earth's total surface area. According to the news a total solar eclipse happens every 18 months or so, but usually over the ocean. I want to figure the odds.

The odds are not that simple. They depend on things like latitude, time of day, etc.
