Light rays.
You have some problem with your eye.
When looking at a distant object, the ciliary muscles in the eye relax, causing the lens to flatten. This allows the light rays from the distant object to focus directly on the retina at the back of the eye, creating a clear image.
Light from the sun travels through the vacuum of space in the form of electromagnetic waves. When it reaches an object, some of the light is absorbed, while the rest is reflected or scattered. The reflected light then travels through the air and enters our eyes, where it is focused by the lens onto the retina. The retina converts the light into electrical signals, which are sent to the brain, allowing us to perceive the object.
How much more light does the sun give off than an object with the least apparent magnitude that can be viewed by the naked eye
When objects are bound gravitationally in centrifugal motion, the objects are said to be in orbit of each other.
Due to the Internal Reflection of light on the object and the observers eye are capable to receive those waves OR On any object light travels through it and by the reflections we can see them.

orbit
A ray that travels towards an object is known as an incident ray. It represents the path of light before it interacts with the object's surface.
Newton's First law means that a force changes either the direction in which an object travels, the speed the object travels,or the shape of the object.
satellite
Satellite.
an satellite
Light travels an infinite distance until it is absorbed by an object.
bob
The velocity of the object.
the object's "speed".(not 'velocity')
