An ordinary star is a star that is not considered to be unique or exceptional in any way. It is a common type of star that follows the standard stages of stellar evolution and does not exhibit any extraordinary characteristics.
The Sun is classified as an ordinary star because it follows the standard stages of stellar evolution, starting as a protostar and eventually becoming a red giant before dying as a white dwarf. It also has a relatively average size, temperature, and luminosity compared to other stars in the universe.
Studying the Sun as an ordinary star allows us to better understand the life cycle and behavior of stars in general. It also provides valuable insight into the physical processes and phenomena that occur within stars, such as nuclear fusion, solar flares, and magnetic fields.
While the Sun is classified as an ordinary star, it does have some unique characteristics such as its relatively stable and long-lasting nature, which has allowed for the development and sustenance of life on Earth. It also has a relatively high abundance of elements like hydrogen and helium, which are essential for nuclear fusion to occur.
Based on current scientific understanding, it is unlikely that the Sun will ever become something other than an ordinary star. It is expected to continue following its standard stages of stellar evolution until it eventually dies as a white dwarf. However, there is always the possibility of new discoveries or unforeseen events that could change our understanding of the Sun's future.
