How do astronomers plot a star's exact position?
Astronomers know that there isn't really a "celestial sphere", a globe of crystal in which the stars are embedded. But it is often convenient to talk of a "sphere" around the Earth, in which all the stars and planets move. And sometimes it makes the math a whole lot easier. Navigators do all their calculations AS IF all the stars were stuck to a crystal sphere, and the Moon and planets wandered around inside it.
What is the study of celestial objects called?
Astronomy is the study of celestial objectsRadio astronomy is the study of celestial objects that emit radio waves.
What is celestial space objects can be meteoroid come from?
The space rock is the celestial space object that a meteoroid comes from.
How do astronomers determine the composition of distant celestial objects?
Spectroscopy is the systematic study of spectra and spectral lines. Spectral lines are used to provide evidence about the chemical composition of distant objects. So the answer to your question is through spectroscopy.. not spectrometry like the previous editor posted.
What does Keplers laws apply to?
Celestial objects in orbit.
How do astronomers use the celestial sphere to plot a star's exact positions?
Astronomers use celestial spheres and mathematical equations to approximate the distances between the star and other celestial objects.
What are protoplanets?
Protoplanets are very small planets, about the size of a moon. Astronomers believe these celestial objects are formed during the creation of a solar system.
Are asteroid belts celestial objects?
No. Asteroid belts are not celestial objects, but asteroids are.
What is the name of the principle employed by early astronomers to determine the distances to celestial objects using the displacement of the apparent position of an object viewed along two different?
parallax
How did the ancient Greeks study stars?
The ancient Greeks developed instruments such as the armillary sphere to track the movement of objects in the plane of the celestial equator against the annual motion of the Sun. This basic device consisted of a set of graduated rings that represented important circles on the celestial sphere, such as the horizon, the celestial equator, the ecliptic, and the meridian. These rings formed a skeletal celestial sphere. A movable sighting arrangement allowed early astronomers to observe a celestial object and then read off its position using the markings on the relevant circles.Ptolemy and other Greek astronomers used the quadrant, a graduated quarter of a circle constructed to allow an observer to measure the altitude of celestial objects above the horizon. An astronomer would sight a target celestial object along one arm of the quadrant and then read off its elevation from a scale (from 0 to 90 degrees) with the help of a plumb line suspended from the center of the quarter circle. With this arrangement a celestial object just on the horizon would have an elevation of 0 degrees, while an object at zenith would have an elevation of 90 degrees.(will add more if i find out more)

Why do all celestial objects in space not lie on the celestial sphere?
because the objects exist at different distances from earth.
In the geocentric system of the ancient greeks all objects in space revolved around this?
The world, planet earth. Geo (earth, world) + centric (centered around)
