It is one of the nearest stars to the Sun. [14], Wolf 359 is classified as a UV Ceti-type flare star,[5] which is a star that undergoes brief, energetic increases in luminosity because of magnetic activity in the photosphere. Scientists have long used this parallax effect implying how a star appears to shift against its background when seen from different locations to measure distances to stars. There's no register feature and no need to give an email address if you don't want to. This instrumentation is sensitive enough to detect the gravitational perturbations of massive, short period companions with the mass of Neptune or greater.
