Question

If a lunar eclipse occurs tonight, when is the soonest that a solar eclipse can occur?
$\left( a \right)$ Tomorrow
$\left( b \right)$ In two weeks
$\left( c \right)$ In about six months
$\left( d \right)$ In one year

Answer 1

Hint The cause of lunar eclipse is when the Moon passes through Earth’s shadow. As a result of the Sun, Earth, and Moon ought to be during a line so as for this to happen, lunar eclipses will solely happen throughout a full phase of the moon.

Complete Step by Step Solution Lunar eclipse happens on the total moon day whereas the solar eclipse happens on the new moon day. The distinction between a new moon day and a full phase of the moon day is of fourteen days. Hence, the proper answer is for two weeks.
A solar eclipse is once the Moon moves between the Sun and Earth, casting its shadow on the face of Earth. A solar eclipse will solely happen throughout a brand new moon.
Why don’t we've got a star and satellite eclipses each month?
The Moon’s orbit is inclined by concerning five-degree with relation to the plane of Earth’s orbit, therefore throughout most months, the complete moon passes “north” or “south” of Earth’s shadow, and therefore the new moon’s shadow passes “north” or “south” of Earth. however a few times a year, the points wherever the Moon crosses the plane of Earth’s orbit (called nodes) are lined up with the Sun, and eclipses will occur. There may be anyplace from a pair of - five solar or lunar eclipses a year, looking on once the nodes line up with the Sun-Earth line. One additional thing: a lunar eclipse could appear more common than a solar eclipse, however, that’s simply because you'll witness a lunar eclipse anyplace you'll see the moon, however, a solar eclipse is just visible to you if you happen to be within the comparatively narrow path of the Moon’s shadow.

Option B is correct answer

Note The plane of the planet around the sun, and also the plane of the moon around Earth are tilted to each other about $5.5$ degrees. Throughout a full moon, usually, the moon is higher than or below the shadow of the earth, and there’s no eclipse. However, once the moon is full and we’re on the brink of the nodes of the two planes - we’ll see a lunar eclipse.
