That is called the apparent magnitude. Originally the brightest stars were called "magnitude 1", the weakest that could still be seen with the naked eye, "magnitude 6". The system has been formalized, now certain objects (several planets, the Moon, the Sun, some bright stars) actually have negative magnitudes; and of course, the range has been extended to weak objects that can only be seen with telescopes. In general, a larger magnitude numbers means an object is less bright.

The measure of a star's brightness is its magnitude. A star's brightness as it appears from Earth is called its Apparent Magnitude.Star's brightness is measured by there magnitude.

The intrinsic brightness of a star is called its absolute magnitude. This is a measure of how bright a star would appear if it were located at a standard distance of 10 parsecs (32.6 light-years) from Earth.
A photometer is a device used to measure surface brightness. It detects and quantifies the amount of light emitted by a surface, typically in astronomy to measure the brightness of stars and galaxies.
An apparent magnitude is a measure of how bright a star appears from Earth. The lower the apparent magnitude, the brighter the star appears in the night sky. Negative values indicate very bright stars, while positive values indicate fainter stars.
An astrometer is a device designed to measure the brightness, relation, or apparent magnitude of stars.
there are two separate ways that astronomers measure the brightness of a start, there is actuall and aparent brightness. In apparent brightness, the measure how bright it looks to all the humans on Earth. However, the actual brightness of a star is different. Say a star is really, really bright, but really far away. That star would look preety dim. Or if a star is not so bright, but really close, like the Sun. The actuall brightness of a star is harder to measure, but is possible by use of waves and stuff like that, I don't know too much about actuall brightness
Apparent magnitude is a measure of how bright a star appears from Earth, taking into account its distance and how much light it emits. Absolute magnitude, on the other hand, is a measure of a star's intrinsic brightness if it were observed from a standard distance of 10 parsecs. It helps in comparing the true brightness of stars regardless of their distance from Earth.
