HD 111456

HD 111456 is a star located in the constellation Leo. It is a G5V-type star, meaning it is a main-sequence star similar to the Sun in terms of temperature and luminosity.

HD 111456 is known for its exceptionally slow and uniform rotation rate. This characteristic makes it valuable for asteroseismology studies. Asteroseismology is the study of stellar oscillations, which can provide information about the internal structure and composition of stars. Due to its stable rotation, the oscillations in HD 111456 are less complicated and easier to interpret, leading to more accurate stellar models.

The star's properties have been extensively studied, and it is considered one of the most spherical and slowly rotating stars known. Precise measurements of its shape confirm its near-perfect sphericity, challenging models of stellar formation and evolution.

HD 111456 is not known to host any planets. Further observations are ongoing to understand the full extent of its unusual properties and what they reveal about stellar physics. Its distance from Earth is approximately 171 light-years.
