The Thursday, June 10, annular solar eclipse belongs to Saros series 147, which comprises 80 similar solar eclipses.

The solar Saros cycle groups solar eclipses into families, known as series, of solar eclipses with similar geometries. For example, same lunar nodal occurrence characterizes all solar eclipses in a particular Saros series. The moon's ascending and descending nodes mark intersection points of the lunar orbit with Earth's orbit. The ascending node indicates lunar passage to the north of Earth's orbit while the descending node signifies passage to the south of Earth's orbit.

The shared geometry of occurrence at the moon's ascending node links Saros 147 solar eclipses. The moon exhibits southward movement with each eclipse in Saros 147.

A Saros cycle's duration approximates 6,585.3 days (18 years 11 days 8 hours). Specifically, Saros series 147 lasts for 1,424.38 years, according to NASA (National Aeronautics and Space Administration) Eclipse Web Site's eclipse predictions by NASA astrophysicist, now retired, Fred Espenak. Saros series 147 spans 15 centuries, from the 17th to the 31st centuries.

Saros series 147 comprises 40 partial solar eclipses and 40 annular eclipses. The cycle's eclipses are sequenced as a first set of 21 partial solar eclipses, followed by a set of 40 annular eclipses and concluded with a second set of partial solar eclipses. The final set features 19 partial solar eclipses.

Saros series 147 opened with a partial solar eclipse on Friday, Oct. 12, 1624. A partial solar eclipse on Saturday, Feb. 24, 3049, closes Saros series 147. The opening solar eclipse was a Northern Hemisphere event. The closing solar eclipse will be a Southern Hemisphere event.

June's annular solar eclipse appears as number 23 in the Saros 147 lineup of 80 solar eclipses. The June 2021 event numbers as the second of the Saros series 147 lineup of 40 annular eclipses. June's annular solar eclipse was preceded by the annular set's opener, the annular solar eclipse of Saturday, May 31, 2003. The May 2003 annular eclipse numbered 22 in Saros series 147's overall lineup of 80 eclipses.

The Saros 147 successor to June's annular solar eclipse will appear Tuesday, June 21, 2039. The June 2039 annular eclipse occurs as third of the annular set's 40 events and as 24th in Saros series 147's overall lineup of 80 eclipses.

The annular solar eclipse of Tuesday, July 31, 2706, completes Saros series 147's annular set. The set's 40th and last event numbers as 61st in Saros series 147's overall lineup of 80 eclipses.

The extreme durations of Saros series 147 spotlight Saturday, Nov. 21, 2291, as the longest annular solar eclipse. The November 2291 event will have a duration of 9 minutes 41 seconds. The November 2291 annular solar eclipse numbers as 17th in Saros series 147's set of 40 annular eclipses and as 38th in Saros 147's overall lineup of 80 eclipses.

The shortest annular solar eclipse will take place Thursday, July 19, 2688. The July 2688 event will offer a duration of only 41 seconds. The November 2291 annular solar eclipse numbers as 39th in Saros 147's set of 40 annular eclipses and as 60th in Saros series 147's overall lineup of 80 eclipses.

The takeaways for the Thursday, June 10, annular solar eclipse belonging to Saros series 147 are that the event occurs as second in the Saros series 147's set of annular eclipses and as 23rd in Saros series 147's overall lineup of 80 eclipses; that June 2021's Saros series 147 predecessor was the annular solar eclipse of Saturday, May 31, 2003; and that June 2021's Saros series 147 successor will be the annular solar eclipse of Tuesday, June 21, 2039.

The Nov. 21, 2291, annular solar eclipse's duration of 9 minutes 41 seconds, which far exceeds the June 10, 2021, annular solar eclipse's duration of 3 minutes 51 seconds, qualifies as Saros series 147's longest annular eclipse: "Eclipse map/figure/table/predictions courtesy of Fred Espenak, NASA/Goddard Space Flight Center, from eclipse.gsfc.nasa.gov.," via NASA Eclipse Web Site
