I wish eclipse can occur more often
Me too. It's a pretty cool thing to see an astronomical object obscured by a shadow or another body.
Do you think there are categories of Eclipse that occurs?
There are eclipses that are an occultation, which means they are completely hidden, and there are partially hidden eclipses called transits
What are the measure one should take before viewing an Eclipse?
It would really depend if it were a solar or lunar eclipse. But the alignment of 3 objects is actually called a syzygy.
When did the first Eclipse occur? or has it been happening since the existence of earth?
term eclipse is most often used to describe either a solar eclipse, when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the Earth's shadow. However, it can also refer to such events beyond the Earth–Moon system: for example, a planet moving into the shadow cast by one of its moons, a moon passing into the shadow cast by its host planet, or a moon passing into the shadow of another moon. A binary star system can also
Eclipse
An eclipse is an astronomical event that occurs when an astronomical object is temporarily obscured, either by passing into the shadow of another body or by having another body pass between it and the viewer. This alignment of three celestial objects is known as a syzygy. Apart from syzygy, the term eclipse is also used when a spacecraft reaches a position where it can observe two celestial bodies so aligned. An eclipse is the result of either an occultation (completely hidden) or a transit (partially hidden).
