18661934 is a notable astronomical object identified by its catalog number. It is a star located in the constellation of Cygnus, the Swan. The star is classified as a red giant, a late stage in the life of a star like our Sun. It is approximately 1,500 light-years away from Earth. The star's spectral type is M2 III, indicating it is a cool, red star with a luminosity class of III, which signifies it is a giant star. Red giants are characterized by their large size and relatively low surface temperatures. 18661934 is of particular interest to astronomers due to its variability, as it exhibits changes in brightness over time. This variability is a common characteristic of red giants, which can pulsate and undergo periodic brightening and dimming. The study of such stars provides valuable insights into stellar evolution and the life cycles of stars.
