Question

Why is there no lunar eclipse and solar eclipse every month?

Answer 1

If the orbits of the Moon and Earth lie on the same plane, during the full Moon of every month, we can observe a lunar eclipse. If this is so dining new Moon we can observe the solar eclipse. But Moon’s orbit is tilted 5° with respect to Earth’s orbit. Due to this 5° tilt, only during certain periods of the year, the Sun, Earth and Moon align in a straight line leading to either lunar eclipse or solar eclipse depending on the alignment.
