HD 88133 is an 8th magnitude star in the constellation of Leo. It is classified as a yellow subgiant star (spectral type G5IV). It is slightly more massive than our Sun, cooler and more luminous. As a subgiant, it has left the main sequence and started to evolve towards red gianthood. Located at a distance of 240 light years from Earth it is not in our immediate neighbourhood and thus not visible to the unaided eye. With a small telescope it should be easily visible.
In 2004 a planet was found to orbit the star.[1]
