Question

when do total and partial lunar eclipse occur?​

Answer 1

Explanation:

This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned (in syzygy) with Earth between the other two, and only on the night of a full moon. The type and length of a lunar eclipse depend on the Moon's proximity to either node of its orbit.

Answer 2

lunar eclipse is caused when the moon moves into the shadow of the Earth. ... A partial lunar eclipse occurs when the moon passes into the Earth's umbra region. A total lunar eclipse occurs when the moon entirely circles within the umbra region of the Earth.
