How is the number of light years figured between two celestial objects?

To find the number of light years between two celestial objects, we first find the distance from each object to earth. If we connect the dots between Earth and the two objects, we have a triangle. We to sides lengths of that triangle (the distances between Earth and the objects), and we can measure one angle (the angle at the vertex where Earth is. This is enough information to find the distance between the objects using trigonometry (in this case, the law of cosines).
Finding the distance from Earth to an object can be a bit complex. One commonly used method is to look for a pulsating star. We can figure out the absolute brightness (how bright it is without factoring in distance away) of these stars by how often they pulse. Then we can measure the apparent brightness (how bright it looks to us). We can then use both these values to find the distance to the star. (This also works for some supernovae.)
Another method is to use objects that are considered to be 'standard candles'. These objects do not pulse, but we know the relationship between their absolute brightness, apparent brightness, and distance away.

What does the mass number identify?
The mass number identifies how much an objects weight is.
What is equated credits?
Equated credits are figured on the basis of the number of class (contact) hours per week.They are figured in determining minimum course load and full-time status. Equated credits do not count in figuring your index or toward the total credits required for your degree.
How chemistry is involved in industry?
An imense number of materials and objects are products of the chemical industry.

Does 1 2 3 give a triangular number?
There is no such thing as a "triangular" number (as a number), a triangular number or triangle number counts the objects that can form an equilateral triangle. One object can and Three objects can but not Two objects.
Any Number of celestial bodies that appear as meteors when entering earths atmosphere?
meteoroids
What is difference between a physical quantity and a number?
A physical quantity is a number of object(s) that are tangible objects. A number doesn't have to represent any specific quantity of items, but rather just a quantity in an equation. Phsyical quantity: 5 chairs, 2 apples
Are celestial bodies identified by a 3 axis coordinate XYZ just as terrestrial locations have Latitude and Longitude X and Y cordinates?
Not quite. Instead of being described in Cartesian coordinates such as X, Y, and Z, celestial objects are described in an angular coordinate system sometimes called "rho, theta". These are letters of the Greek alphabet often used to measure angles.We still use three coordinates representing the number of degrees around the ecliptic a celestial object is, and the number of degrees north or south of the ecliptic plane. The third coordinate is a distance. These are similar to the bearing, elevation and range coordinates that you might use in gunnery.
What is constalation a number of?
It is a number of astronomical objects which may be stars, galaxies or other large radiant objects.
How do you work out a mathematical ratio?
Mathematical ratios are similar to fractions or decimals. It is the comparison between 2 different number of objects on either side to determine the equality between the two.
The gravitational force between two objects depends on the distance between the objects and each objects?
You're fishing for the answer "mass", but your bait-statement is misleading.The force doesn't really depend on "each" mass. It depends on the productof the two masses. There are a huge number of individual masses that theycould have and still multiply to the same product, and have the same forcebetween them.
What is a Messier Object?
The Messier objects are a set of astronomical objects catalogued by French astronomer Charles Messier in his catalogue of Nebulae and Star Clusters first published in 1774. The original motivation behind the catalogue was that Messier was a comet hunter, and was frustrated by objects which resembled but were not comets. He therefore compiled a list of these objects.[1] The first edition covered 45 objects numbered M1 to M45. The total list consists of 110 objects, ranging from M1 to M110. The final catalogue was published in 1781 and printed in the Connaissance des Temps in 1784. Many of these objects are still known by their Messier number.[2] Because Messier lived and did his astronomical work in France in the Northern Hemisphere, the list he compiled contains only objects from the north celestial pole to a celestial latitude of about -35°. Many impressive Southern objects, such as the Large and Small Magellanic Clouds are excluded from the list. Because all of the Messier objects are visible with binoculars or small telescopes (under favorable conditions), they are popular viewing objects for amateur astronomers. In early spring, astronomers sometimes gather for "Messier marathons", when all of the objects can be viewed over a single night. Answer from Wikipedia and all of its sources
