The inside of a planetarium is a sphere with the stars and planets projected on to it. The celestial sphere is an infinite sphere that we imagine has the stars and planets on it. On the celestial sphere only an object's direction matters and its distance is ignored.
A viewer at the centre of the planetarium sees stars and planets as they appear in the sky, but viewers in all the seats see approximately the right view.
No, because there is no such thing as the celestial sphere. So there is no inner surface of a celestial sphere.
The largest sphere that can fit around Earth is the geocentric celestial sphere. This imaginary sphere has Earth at its center and encompasses all celestial objects visible in the sky.
No.
In the Ptolemaic Greek model of the universe, the stars are thought to be attached to the celestial sphere, a hypothetical invisible sphere surrounding the Earth to which the stars were fixed. This model placed Earth at the center of the universe with all celestial bodies orbiting around it.
The central star projector in the National Museum Planetarium in Rizal Park, Manila,is a Goto model GM-15. The model dates from the early 1970s, and was manufacturedin Tokyo by Mitsubishi.
No, because there is no such thing as the celestial sphere. So there is no inner surface of a celestial sphere.

Plants are not located on the Celestial Sphere. The Celestial Sphere is an imaginary sphere surrounding the Earth, used to map the positions of stars and celestial objects in the sky. Plants are living organisms found on Earth's surface.

These are imaginary locations in the sky. The "celestial sphere" is a blanket term for everything beyond the Earth. The celestial equator is the plane of the Earth's equator extended out into space. The "celestial poles" are extensions of the north pole and south pole into space. It's sometimes convenient to describe objects out in space with reference to terrestrial coordinates.

The imaginary sphere that surrounds the Earth is called the celestial sphere. It is an abstract sphere of infinite radius upon which all celestial objects are assumed to lie. It provides a convenient reference frame for locating celestial objects in the sky.

The projector used in a planetarium is commonly known as a "star projector" or "planetarium projector." These devices are designed to simulate stars, planets, and other celestial phenomena on the dome of the planetarium. Modern planetarium projectors can also incorporate digital technology to display more complex visuals and immersive experiences.
