The brightness level perceived by the unaided human eye is referred to as "apparent magnitude." This scale measures the brightness of celestial objects as seen from Earth, with lower numbers indicating brighter objects. For example, a star with a magnitude of 1 is brighter than one with a magnitude of 6, which is near the limit of visibility for the average human eye in dark conditions.

What is a star's level of brightness as viewed by the unaided?
A star's brightness as viewed by the unaided eye is measured using a scale called apparent magnitude. This scale quantifies how bright a star appears from Earth, with lower numbers indicating brighter stars. For example, a star with an apparent magnitude of 1 is brighter than one with a magnitude of 6, which is at the limit of what the average human eye can see under ideal conditions. Factors influencing a star's apparent brightness include its intrinsic luminosity, distance from Earth, and any interstellar material that may dim its light.
Can neptune be seen with out a telescope at night?
No. Its brightness is below the limit of sensitivity for the unaided human eye.
What is the smallest microorganism seen by the human eye?
The smallest microorganism seen by the human eye is likely a single-celled organism called a paramecium, which can range in size from 50 to 300 micrometers. These organisms are barely visible to the naked eye and can be viewed using a light microscope.
What is one thing a unaided human eye can see?

Can a human draw a perfect circle?
As far as an UNAIDED human, no it is not possible. By unaided - nothing other than their writing utensil, hand and the surface being drawn on with no guide, tools, marks or the like.
Can an unaided human eye tell if light is polarized?
An unaided human eye cannot directly detect light polarization. However, certain phenomena, such as the visibility of glare from surfaces like water or roads, can indicate polarization. By using polarized sunglasses, individuals can observe changes in brightness and glare, which can help them infer the presence of polarized light. Ultimately, while the eye itself cannot determine polarization, it can perceive effects related to it.
The study of lighting is called?
The study of lighting is called photometry. It focuses on the measurement of light in terms of its perceived brightness by the human eye.
How to pass thread through the eye of a needle unaided?
Pass a thread through the eye of a needle unaided from the opposite side of the needle towards the human eye; while looking through the eye of the needle.
What is the smallest size of a cell that can be seen with an unaided human eye in term of micron?
The smallest size of a cell that can be seen with the unaided human eye is about 100 microns, which is roughly the size of a grain of sand. Anything smaller than that would generally require a microscope to be visible.
What makes an organism a microorganism?
Any organism which is too small to be seen with the unaided human eye is by definition a microorganism.
When the amount of light reflected increases called?
When the amount of light reflected increases, it is referred to as brightness or luminance. This is a measure of how intense the light appears to the human eye.
How is reproductive viewed by human society?
well there is a human society, isn't there?
