List of star extremes

A star is a massive luminous spheroid astronomical object made of plasma that is held together by its own gravity. Stars exhibit great diversity in their properties (such as mass, volume, velocity, stage in stellar evolution, and distance from Earth) and some of the outliers are so disproportionate in comparison with the general population that they are considered extreme. This is a list of such stars.

Records that are regarded as authoritative and unlikely to change at any given point are recorded on a white background, while those that could change with new information and/or discoveries are recorded on a grey background.
