A solar eclipse is an astronomical event that occurs when an astronomical object or spacecraft temporarily goes dark, enters the shadow of another body, or passes another body between it and the observer. This alignment of three celestial bodies is called a syzygy. In addition to syzygy, the term eclipse is also used when a spacecraft reaches a position where it can observe two celestial bodies aligned. A solar eclipse is the result of an occultation (completely obscured) or a transit (partially obscured). The term solar eclipse is most commonly used to describe a solar eclipse, when the moon’s shadow crosses the Earth’s surface, or a lunar eclipse, when the moon moves through the earth’s shadow. But it can also refer to such events outside the Earth-Moon system: for example, a planet moving into the shadow of one of its moons, a moon sinking into the shadow of its host planet, or a moon sinking moves towards the Shadow casts shadows . from another moon A binary star system can also produce eclipses when the plane of the orbit of its components intersects the observer’s position. For special cases of solar and lunar eclipses, these occur only during an “eclipse season,” the two periods per year when the plane of Earth’s orbit around the Sun intersects the line of intersection of planes near the Sun. Sun The type of eclipse that occurs during each season (total, annular, hybrid, or partial) depends on the apparent size of the sun and moon. If the Earth’s orbit around the Sun and the Moon’s orbit around the Earth were both in the same plane, solar eclipses would occur every month. There would be a lunar eclipse every full moon and a solar eclipse every new moon. And if both orbits were perfectly circular, then all eclipses in any month would be of the same type. Due to non-planar and non-circular differences, eclipses do not occur frequently. Lunar eclipses can be seen from all night hemispheres on earth. But solar eclipses, especially total eclipses, that occur at a specific point on the earth’s surface are very rare events that can be decades apart.
