Solar eclipses are grouped by their saros number, each series lasts between 1200 and 1600 years and contains from 69 to 87 solar eclipses (most often 70 to 73).Solar eclipses in odd series exist at the ascending node of the Moon's orbit, and even series occur at the descending nodes.

Afternoon analemma photo taken in 1998–99 in Murray Hill, New Jersey, U.S., by Jack Fishburn.The Bell Laboratories building is in the foreground. In astronomy, an analemma (/ ˌ æ n ə ˈ l ɛ m ə /; from Ancient Greek ἀνάλημμα (analēmma) 'support') [a] is a diagram showing the position of the Sun in the sky as seen from a fixed location on Earth at the same mean solar time over ...
Martin suggested that the conventional orrery should consist of three parts: the planetarium where the planets revolved around the Sun, the tellurion (also tellurian or tellurium) which showed the inclined axis of the Earth and how it revolved around the Sun, and the lunarium which showed the eccentric rotations of the Moon around the Earth. In ...
In April 2014, the first measurement of a planet's rotation period was announced: the length of day for the super-Jupiter gas giant Beta Pictoris b is 8 hours (based on the assumption that the axial tilt of the planet is small.) [27] [28] [29] With an equatorial rotational velocity of 25 km per second, this is faster than for the giant planets ...
A symbolic orbital diagram from the view of the Earth at the center, showing the Moon's two nodes where eclipses can occur. Up to three eclipses may occur during an eclipse season, a one- or two-month period that happens twice a year, around the time when the Sun is near the nodes of the Moon's orbit.
The eclipse day started cloudy, but the sky cleared and the Moon's disk began to obscure the Sun shortly before 8:56 am; the eclipse lasted 5 minutes 13 seconds. The team remained at Sobral until July to photograph the same star field at night.
