The "equatorial plane".
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 celestial equator is an imaginary circle created by extending Earth's equator into space. Zenith is an imaginary point in the sky directly above and observer on earth.
Polaris is the star nearest to the imaginary extension of the North pole into space

There is no physical boundary between the northern and souther hemispheres. However, the imaginary line which is at 0o latitude is called the equator.
Objects that are "stationary" on Earth's surface are moving faster nearer the equator. The eastward motion of the rotating Earth is greatest at the equator (about 1037 mph or 1670 kph).
There is an imaginary plane through the Earth that splits the world into "north" and "south". The circle around the Earth where that plane meets the Earth's surface is called the "equator". In astronomy, we extend that plane into space; this is the "celestial equator". With geography on the Earth, we measure this in latitude north or south of the equator. In astronomy, we call it "declination", but it's the same idea.
That imaginary line is called as "ORBIT".. Each space object spins around itself, in a particular path called as "ORBIT"
The four imaginary space relationships that every drawing has are: Projection plane, Frontal plane, Horizontal plane, & Profile plane.
An intraartucular extension is a type of fracture that protrudes into the articulating joint space. Simply, it is a fracture that involves the joint space.
