A lunar eclipse occurs at least 19-20 times in a span of 18 years.Both solar eclipse and lunar eclipse are among the most amazing celestial events visible from earth. A solar eclipse occurs at least 66 times as a whole in a century. If we consider these phenomena then the frequency of solar and lunar eclipse can be determined.
SOLAR VS LUNAR ECLIPSE FULL
The earth covers the moon for more than an hour on a full moon night. The solar eclipse occurs on a new moon day where the moon overshadows the sun for a particular location for only 7.5 minutes. This makes a huge difference as the moon can easily pass through it during the full moon and new moon days. The plane of the earth’s orbit and that of the moon has a difference of 5°.
It happens only when the planes of the sun, earth, and the moon intersects. Remember that every new moon will not cause a solar eclipse or every full moon will experience a lunar eclipse at night. The frequency of solar and lunar eclipses depends on the span of the moon and the earth. The difference in the solar and lunar eclipses can be easily explained by the geometry of these bodies. What is the Frequency of Solar and Lunar Eclipses? Hence, the latter can only guard the sun for 7.5 minutes whereas the earth’s shadow covers the moon for an hour. Similarly, the sun’s diameter is multiple times bigger than the moon’s. It takes an hour or more to complete a lunar eclipse due to the huge difference between the earth’s diameter and the moon’s diameter. The differences in the geometrical shape and diameter of these heavenly bodies also decide the span of eclipses. As the moon’s diameter is quite smaller than the sun, the occurrence of this eclipse is less at a particular point. If you check how long a solar eclipse lasts, you will clearly understand the difference. As we know that the lunar eclipse occurs due to the earth’s shadow cast, the pan of this shadow increases the frequency of the lunar eclipse. The diameter of the moon is way less than that of the earth. The frequency of solar and lunar eclipses shows the difference in the geometry of these cosmic bodies. Despite the fact, an observer can witness at least 19-20 lunar eclipses within a time span of 18 years. In some years, it can occur thrice and in some none.
There is no particular count of the lunar eclipse in a year. A lunar eclipse occurs two times a year generally. This is the difference between the solar and lunar eclipse. How Many Times Does a Lunar Eclipse Occur in a Year? Hence, the shape of the earth’s shadow totally engulfs the moon for a longer period of time. It happens due to the reason that the earth’s diameter is greater than the moon. The lunar eclipse duration is much more than the solar eclipse. The engulfment of the moon by the earth’s shadow occurs for an hour. The entire moon stops receiving sun rays from the sun and turns out to be lack. Solar eclipses last for only 7.5 minutes.Īs mentioned earlier, a lunar eclipse occurs when the earth comes in between the sun and the moon. This is how often solar eclipses occur in a particular location. In fact, these calculations suggest that a point on the earth will experience one total solar eclipse in 3 to 4 centuries. Between 20, the total eclipses that will occur are 224. The total number of solar eclipses is 66 on average.Īs per the calculations, the solar eclipse that occurred between 19 is 228. In the year 1935, 5 solar eclipses have occured and it will happen again in 2206. As per the calendar we use, solar eclipse generally occurs 2 to 5 times a year. A partial interception occurs in the penumbra region. When blocked, the sun in the umbra region is totally intercepted by the moon. These rays were supposed to fall on the earth’s surface. It happens when the moon comes in between the earth and sun interrupting the sun rays emitted from the sun. You have studied solar eclipse in the previous classes.
We will also learn the reason behind the frequency of these eclipses. In this section, we will discuss the frequency of solar and lunar eclipses and how long they last. When the earth comes between the sun and the moon, we witness a lunar eclipse. When the moon comes between the sun and the earth, we witness a solar eclipse. The solar and lunar eclipse is a natural phenomenon that occurs when there is an interception of the sun rays done by the moon or the earth.
