167169C

167169C is a celestial object located in the constellation of Sagittarius. It is classified as a carbon star, a type of red giant star characterized by the presence of carbon in its atmosphere. Carbon stars are known for their distinctive red color, which is a result of the absorption of blue light by carbon molecules in the star's outer layers.

The star 167169C is notable for its variability. It is a semi-regular variable star, which means its brightness fluctuates over time in an irregular pattern. This variability is a common characteristic of carbon stars, and it is thought to be caused by pulsations in the star's outer layers.

The star is located approximately 1,500 light-years away from Earth. Its exact distance and other physical properties, such as its mass and radius, are not well-determined due to the challenges of observing such distant objects. However, it is estimated to be several times larger than the Sun and to have a relatively low surface temperature, which contributes to its red color.

Carbon stars like 167169C are of interest to astronomers because they are thought to be in an advanced stage of stellar evolution. They are believed to be the result of the fusion of helium in the core of a star, which leads to the production of carbon. As the star ages, it expands and cools, becoming a red giant before eventually shedding its outer layers to form a planetary nebula.
