There will be a total solar eclipse on July 16, 2186, passing over the southern Galápagos Islands (with a maximum eclipse of 4 minutes occurring over the southern tip of Española Island), northern South America, specifically, the northern tip of Ecuador (with a maximum totality of 3 minutes and 26 seconds on Isla Santa Rosa), central Colombia (including Bogota which will experience 4 minutes and 50 seconds of totality), central Venezuela, and northern Guyana (with a maximum eclipse of 7 minutes 4 seconds just north of Anna Regina).[1]

Extreme Duration

This will be the longest total solar eclipse between the dates of 4000 BC and at least 8000AD, lasting a maximum of 7 minutes, 29 seconds. The factors that will make this such a long eclipse are:

  • The Earth being very near aphelion (furthest away from the Sun in its elliptical orbit, making its angular diameter nearly as small as possible). This occurs around July 6th.
  • The Moon being almost exactly at perigee (making its angular diameter as large as possible). The moment of greatest eclipse will be just 50 minutes after perigee.[2]
  • The midpoint of the eclipse being very close to the Earth's equator, where the orbital velocity is greatest.
  • The midpoint of the eclipse being near the subsolar point (the part of the Earth closest to the Sun, and therefore also closest to the Moon during an eclipse).
  • The vector of the eclipse path at the midpoint of the eclipse aligning with the vector of the Earth's rotation (i.e. not diagonal but due east). For solar eclipses at the ascending node (odd numbered saros) this occurs approximately 12 days after the summer solstice.[3][4]

The longest historical total eclipse lasted 7 minutes 28 seconds on June 15, 744BC.[5] The longest eclipse theoretically possible for the 3rd millennia is 7 minutes and 32 seconds.[6]

Saros 139

It is a part of saros series 139, repeating every 18 years, 11 days, containing 71 events. The series started with partial solar eclipse on May 17, 1501. It contains hybrid eclipses on August 11, 1627 through December 9, 1825 and total eclipses from December 21, 1843 through March 26, 2601. The series ends at member 71 as a partial eclipse on July 3, 2763. Members in the same column are one exeligmos apart and thus occur in the same geographic area.

The solar eclipse of June 13, 2132 will be the longest total solar eclipse since July 11, 1991 at 6 minutes, 55 seconds.

The longest duration of totality will be produced by member 39 at 7 minutes, 29 seconds on July 16, 2186.[7] This is the longest solar eclipse computed between 4000BC and 6000AD.[8]
