What units of measurement do you measure the brightness 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
How much magnitude brightness do the stars have in Cassiopeia?
3.33
What term is used to describe a star's brightness?
It is called Vmag. This is the visual magnitude of the object. Visual magnitude is a scale used by astronomers to measure the brightness of a star or other celestial object. Visual magnitude measures only the visible light from the object. The lower the V-MAG the brighter the star. You can go to http://seasky.org/pictures/sky7b14.html to learn more.
What object could you use to measure the brightness of the bulb?
An item called a LUX meter is usually used for the determination of the brightness of a light bulb. It is generally a meter that measures the amount of incident white light.
A star's brightness as if it were a standard distance is called?
Absolute Brightness .
What the measure of a stars brightness called?
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.
What is the measure of a stars brightness?
Magnitude.
What is the measure of the star's brightness?
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.
What is the stars intrinsic brightness called?
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.
Stars that can change their brightness?
the moon can vary its brightness and the pink elephant called aphadophalis
A measure of a stars brightness is called its?
Magnitude. First magnitude descibes many bright stars, and a span of five magnitudes represents a difference of a hundred times in the star's brightness. The dimmest stars seen by a perfect human eye in perfect conditions is 6th magnitude.
Unit used to measure the stars is called a?
magnitude for brightness, lightyear for distance, degrees C or K for temperature or colour, solar masses for mass, ...
What is the device that measured Surface brightness?
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.
What is an astrometer?
An astrometer is a device designed to measure the brightness, relation, or apparent magnitude of stars.
What is the unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
What is the standard measure used to determine the brightness of a light bulb?
The standard measure used to determine the brightness of a light bulb is called lumens.
What is the standard unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
