The hottest stars are typically classified as O-type stars, which have surface temperatures exceeding 30,000 Kelvin (K). Among the known stars, one of the hottest is **HD 93129A**, located in the Carina Nebula, which has a surface temperature of around 50,000 K. Another contender is **WR 102**, a Wolf-Rayet star, which also has extremely high temperatures, potentially similar or higher than that of HD 93129A.
In general, O-type stars are characterized by their blue color, immense brightness, and high mass, and they tend to have short lifespans, often only a few million years.
