The azimuthal grid is a coordinate system that stays still while the stars move across it on the sky (the celestial sphere). It measures the altitude above the horizon and the azimuth (position along the horizon) of the celestial object at a particular time, for a particular place.

The imaginary sphere is called the celestial sphere because it provides a simplified model for understanding the positions and movements of celestial objects as they appear from Earth. By projecting the stars, planets, and other astronomical bodies onto this sphere, we can easily map their locations in the sky. This concept helps astronomers and navigators visualize the cosmos, despite the vast distances involved. The term "celestial" reflects its association with the heavens and the celestial bodies observed within it.
An armillary sphere is a model of the celestial sphere that represents the apparent motion of the stars and planets around the Earth. It consists of a series of rings, or armillae, that represent the celestial equator, ecliptic, and other key celestial circles. Historically, it was used for teaching astronomy, demonstrating the positions of celestial bodies, and aiding in navigation. Additionally, it illustrates concepts like celestial coordinates and the relationship between the Earth and the heavens.
No, because there is no such thing as the celestial sphere. So there is no inner surface of a celestial sphere.
Yes, latitude and right ascension are both coordinate systems used for locating objects on the celestial sphere. Latitude is measured in degrees north or south of the celestial equator, while right ascension is measured in hours, minutes, and seconds eastward from the vernal equinox. Right ascension is analogous to longitude on Earth.

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.

celestial sphere
The celestial sphere is an imaginary sphere surrounding the Earth, with celestial equator and celestial poles located on it. The celestial equator is an extension of Earth's equator onto the celestial sphere, while the celestial poles are the points where Earth's rotation axis intersects the celestial sphere. These features can be observed in the night sky.
Celestial Equator
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.

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.
