Introduction
Eclipses can only occur when the Sun, Earth, and Moon are all in a straight line. Solar occur at new moon, when the Moon is between the Sun and Earth and in contrast, lunar eclipses occur at full moon, when Earth is between the Sun and Moon. The apparent size of the Moon is roughly the same as that of the Sun, with both being viewed at close to one-half a degree wide. The Sun is much larger than the Moon but it is the precise vastly greater distance that coincidentally gives it the same apparent size as the much closer and much smaller Moon from the perspective of Earth. In a total eclipse, the Moon completely covers the disc of the Sun and the solar corona becomes visible to the naked eye. Because the distance between the Moon and
Question 1
Explain about the effect of eclipse due to earth?
The Earth rotational axis is tilted 23.5 degrees from the perpendicular of its orbit. The equator is tilted at the same 23.5 degrees from the perpendicular of the Earth orbit as well.
As the Earth travels around the Sun, the rotational axis actually stays pointed in the same celestial location the North Star. And because of the rotational axis tilt angle, and as the Earth travels around the Sun, the Sun appears to travel up and down the Earth creating the seasons with the longer daylight in the summer and less daylight hours in the winter. The high and low points of this sun 'travel' are the Tropic of Cancer and Tropic of Capricorn.
Question 2
Explain about the effect of eclipse due to moon?
As the Moon is continuously blocking the view of a half-degree-wide circular area of the sky, the related phenomenon of occultation occurs when a bright star or planet passes behind the Moon and is occulted(hidden from view). The Moon is comparatively close to Earth, occultation of individual stars are not visible
