It must either reflect light, as in the case of the Moon under ordinary circumstances, or block light, as in the case of the Moon during a solar eclipse.
Of course in everyday life, almost everything we see on Earth is seen by reflected light.
PS: in reality, every object with a temperature above absolute zero, in other words, every object, emits light in the form of infrared radiation. We just can't see it without instruments or special cameras.
An object that is visible because of reflected light is called "luminous" or "reflective."
When light falls on some object, then it absorbs all the colors of visible light spectrum except the color of the object itself which it reflects back (diffusion). So we see the color of the object .
A black object gets warm when visible light shines on it because the object absorbs the light energy instead of reflecting it. This absorbed energy causes the object's molecules to vibrate and generate heat.
An object would appear black if:it did not emit any visible radiation.it was in an environment where there was no ambient visible radiation present.the compounds on its surface absorbed all radiation comprising the visible spectrum.
The color that an object appears to be depends on the wavelengths of visible light that are absorbed and reflected by the object's surface. Objects absorb certain wavelengths and reflect others, with the reflected wavelengths determining the color we perceive.
because light used to see an object must have a wavelength
A visible object.
The light the object reflects.
An object that is visible because of reflected light is called "luminous" or "reflective."
When visible light strikes an object, it can be absorbed, transmitted, or reflected. The color of the object is determined by which wavelengths of visible light are reflected back to our eyes. Objects that appear white reflect most of the visible light, while objects that appear black absorb most of the visible light.

When it is not in front of an object that has no color.
The smallest object visible to the human eye is about 0.1 millimeters in size, which is roughly the width of a human hair.
In that case, both variables will point to the same object. Changes done through one object reference will also be visible if you access the object through the other object reference.In that case, both variables will point to the same object.

The moon is visible for the same reason every object is visible: it reflects light.

The net force acting on the object must be zero. The net torque acting on the object must be zero. The object must not be accelerating. The object must be in a stable position. The object must have no external disturbances acting on it.
