How frequently did the total solar eclipse occur in 2009?
For a fixed point, the total solar eclipse usually occurs once every 300 to 400 years, and the time span varies from place to place. Take Shanghai as an example. The last total solar eclipse occurred in 1575, and the next one will occur in 2309.
From a professional point of view, for the same place, the frequency of total solar eclipse is generally around 300 years. But the frequency of total solar eclipse should not be the focus of attention. No matter how many years it has happened, it is certain that this is a very spectacular astronomical spectacle, which deserves our treasure.
Extended data:
Solar eclipse, also called solar eclipse, is an astronomical phenomenon. When the moon moves between the sun and the earth, for some parts of the total solar eclipse on the earth, the moon blocks some or all of the sunlight, and it seems that some or all of the sun has disappeared. This is a lunar eclipse. Eclipses only occur when the new moon, the moon and the sun meet.
Solar eclipse is a very rare phenomenon. Among the three kinds of solar eclipses, total solar eclipse is relatively rare, because only when the umbra of the moon is projected on the surface of the earth can people in this area observe the solar eclipse.
Total solar eclipse is a magnificent natural landscape, so it often attracts many tourists to watch it overseas. For example, the total solar eclipse in Europe in 1999 attracted many tourists, and some travel agencies also launched itineraries specially designed for these tourists.
