An eclipse is an astronomical event that occurs when an astronomical object or spacecraft is temporarily obscured, by passing into the shadow of another body or by having another body pass between it. This alignment of three celestial objects is known as a syzygy.

As we all know eclipse happens once in a while and as well it also set to happen this year and that on 21st of June.

what really is an "Eclipse...?

1. Eclipse is an alignment of astronomical objects whereby one object comes between the observer (or notional observer) and another object, thus obscuring the latter.

2. Eclipse an alignment whereby a planetary object (for example, the Moon) comes between the Sun and another planetary object (for example, the Earth), resulting in a shadow being cast by the middle planetary object onto the other planetary object.

Note: There are different types of eclipse and these are.

1. Annular Eclipse.

2. Hybrid Eclipse.

3. Total Eclipse.

4. Partial eclipse: In a partial eclipse, the Moon crosses the path of the sun, but does not completely block it out.

5. A solar eclipse is when the sun is covered by the Moon.

Meanwhile total solar eclipse are rare, though they occure somewhere on earth probably every 18months on average and it is estimated that they occure at any given place only once every 360 to 410 years.

it takes approximately 375 years for a total solar eclipse to happen at same location and by comparison, a total lunar eclipse, also known as a "Blood Moon", can be seen from any location approximately every 2.5 years.

Therefore, how will the eclipse of June 21st 2020 occur.

An annular solar eclipse will occur on June 21st, 2020. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth.
