This chart ranks the brightest objects in Earth's sky by apparent magnitude, where lower and more negative values mean brighter. It includes the Sun, Moon, planets and stars together, showing why some planets outshine every star.
About: Brightest Objects in the Night Sky
Overview of the data behind this chartAI Insight
The Sun overwhelms everything at apparent magnitude -26.7, roughly 400,000 times brighter than the full Moon (-12.7), the second brightest object in our sky. After these two, the planet Venus (-4.6) outshines every star, appearing as the brilliant 'morning' or 'evening star,' followed by Jupiter and Mars (both around -2.9) and Mercury (-1.9). Only then comes the brightest true star, Sirius (-1.46). This ordering reveals a key point: apparent brightness depends on distance and reflectivity, not just intrinsic power. The nearby planets shine by reflecting sunlight and so appear brighter than vastly more luminous but far more distant stars. The scale is logarithmic, so the roughly 25-magnitude gap between the Sun and Sirius represents a brightness difference of many billions of times.
