What are the differences between solar and lunar eclipses in Vietnam?
* What is a solar eclipse?
A solar eclipse is a phenomenon that occurs when the Moon passes between the Sun and the Earth, obscuring a part or the entire sunlight reaching the Earth. This event only occurs during the day and when the Moon is in the new moon phase.
There are three main types of solar eclipses:
- Total solar eclipse: The Sun is completely obscured by the Moon.
- Partial solar eclipse: The Moon only covers a part of the Sun.
- Annular solar eclipse: The Sun is almost entirely covered, leaving a thin ring of light surrounding the Moon.
* What is a lunar eclipse?
A lunar eclipse is a phenomenon that occurs when the Earth passes between the Sun and the Moon, blocking the sunlight from reaching the Moon. This event only happens at night and when the Moon is in the full moon phase.
There are three main types of lunar eclipses:
- Total lunar eclipse: The entire Moon is covered by the Earth's shadow.
- Partial lunar eclipse: Only part of the Moon enters Earth's shadow.
- Penumbral lunar eclipse: The Moon is only faintly shaded by Earth's penumbral shadow.
* What are the differences between solar and lunar eclipses in Vietnam?
Solar and lunar eclipses are both astronomical phenomena involving the Sun, the Moon, and the Earth, but they differ in occurrence, observation time, and formation causes. Below are the key differences between these two phenomena:
Criteria | solar eclipse | lunar eclipse |
Cause | The Moon passes between the Sun and the Earth, blocking the Sun's light. | The Earth passes between the Sun and the Moon, blocking light from reaching the Moon. |
Time of Occurrence | Occurs only during the day. | Occurs only at night. |
The phase of the Moon | Happens when the Moon is in the new moon phase. | Happens when the Moon is in the full moon phase. |
Observability | Can only be observed in certain areas on Earth. | Can be observed from anywhere on Earth if the Moon is above the horizon. |
Observed Phenomenon | The Sun is partially or totally obscured. | The Moon gradually darkens and may turn a reddish-orange color. |
Frequency | Be rarer than lunar eclipse and occur 2–5 times a year, but a total solar eclipse at a single point is very rare. | Occur more frequently, averaging 2–4 times a year. |
Safety of Observation | Eye protection is necessary when observing directly, otherwise, it can cause eye damage. | Safe to observe with the naked eye, and no protective equipment is needed. |
