It is so that you can see things that are far off as though they are a lot closer. So when Galileo decided to turn a telescope on Jupiter he discovered the four moons. But he was dead against anyone else's discoveries.
The list of choices you included with your question doesn't include any part of atelescope that can do that. I would have picked the objective, whether a lens ora mirror.
Telescope eyepieces are important of any visual telescope. It is the main part of the telescope and is what determines how the object will look like through the telescope.
The telescope you are referring to is likely a refracting telescope. In a refracting telescope, light enters through an objective lens which bends the light rays to a focal point where the image is formed. This type of telescope is commonly used in astronomy and for terrestrial viewing.
An orbiting telescope is a telescope that transferring infared light into visual light while orbiting in space.An orbiting telescope is a telescope that transferring infared light into visual light while orbiting in space.
simplest possible telescope
radio telescope detects radio waves and a light telescope views light waves.

An optical telescope focuses and concentrates visible light; radio telescopes focus and concentrate electromagnetic radiation (which means, "light") in the radio part of the spectrum.
A radio telescope detects light in the form of radio waves and a refracting telescope detects light in the visible wavelengths
Telescope eyepieces are important of any visual telescope. It is the main part of the telescope and is what determines how the object will look like through the telescope.
The light gathering power of a telescope is directly proportional to the area of the objective lens of the telescope.

A reflecting telescope.
The telescope you are referring to is likely a refracting telescope. In a refracting telescope, light enters through an objective lens which bends the light rays to a focal point where the image is formed. This type of telescope is commonly used in astronomy and for terrestrial viewing.
To find the aperture of a reflecting telescope, you would measure the diameter of the primary mirror. The aperture of a telescope is the diameter of its primary light-gathering element, which in the case of a reflecting telescope, is the primary mirror.
