Celestial Mechanics. Or Astronomy
Astronomy: Noun: The branch of science that deals with celestial objects, space, and the physical universe as a whole.
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.
Latitude is not based on any celestial observation, but rather the geographical location - how far north or south the place is - with respect to the equatorial circle. You could say it is based on terrestrial observation, if you like.
Terrestrial navigation refers to the process of navigating through the use of landmarks, the positions of celestial bodies, or other references on the Earth's surface. It includes methods such as using maps, compasses, GPS, and sextants to determine one's location and course on land.
The celestial coordinate system is exactly analogous to the terrestrial positioning system based on latitude and longitude. Terrestrial latitude ---> celestial 'declination'. Terrestrial longitude ---> celestial 'right ascension', where one 'hour' = 15 degrees.

The opposite word of celestial is terrestrial, which refers to things that relate to or exist on Earth.
An observatory is a location used for observing terrestrial and/or celestial events.
Nutation in celestial mechanics causes a slight wobbling or nodding motion in the Earth's axis of rotation, which affects the orientation of the Earth's axis in space over time.
This explanation unified the motion of celestial bodies and motion of objects on earth.

The two-body problem in classical mechanics is significant because it involves the study of the motion of two interacting bodies under the influence of gravity. This problem is important in celestial mechanics as it helps us understand the motion of celestial bodies like planets and moons in our solar system. By solving the two-body problem, scientists can make predictions about the orbits and interactions of celestial objects, leading to a better understanding of the dynamics of the universe.
