S32430

S32430 is a star located in the constellation of Cassiopeia. It is a member of the open cluster NGC 7789, also known as Caroline's Rose. The star is classified as a blue-white subgiant, with a spectral type of B8IV. Its apparent magnitude is 10.1, making it too faint to be seen with the naked eye but visible with amateur telescopes under dark skies.

S32430 is approximately 7,900 light-years away from Earth. It has a mass about 3.5 times that of the Sun and a radius roughly 3.2 times larger. The star is relatively young, with an estimated age of about 100 million years. Its surface temperature is around 12,000 Kelvin, which contributes to its blue-white color.

The star's designation, S32430, comes from the Strömgren photometric system, which is used to study the properties of stars. The system assigns a unique identifier to each star based on its position and brightness. S32430 is one of the many stars in the NGC 7789 cluster, which is known for its rich population of hot, young stars.

NGC 7789 is a prominent open cluster in Cassiopeia, visible through binoculars or a small telescope. The cluster is estimated to be about 1.6 billion years old and contains over 100 stars brighter than magnitude 14. S32430 is one of the brighter members of this cluster, making it an interesting target for astronomers studying star formation and evolution.
