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 hangs out between mars and Jupiter?
The asteroid belt can be found located between Jupiter and Mars. It contains a large number of irregularly shaped celestial bodies.
What is the apparent brightness of a star as represented by a number on a logarithmic scale?
The apparent brightness of a star is represented by its apparent magnitude, which is a logarithmic scale used to measure the brightness of celestial objects as seen from Earth. The lower the apparent magnitude number, the brighter the star appears in the sky. Each increase of one magnitude corresponds to a brightness factor of 2.5.

Why a fixed magnet attract a iornic objects eventhough magneticfield doesn't do any work?
Iron has a very high permeability. So it lets maximum number of Magnetic lines of force to pass through it. The closer is the ironic conductor to the magnet, more is the number of lines of force passing through the ironic object. That is why the magnet attracts the ironic object.

What does Difference Between discuss on their website?
The website Difference Between discusses on their website a number of different terms and objects. Site visitors can find various information regarding differences between objects and terms.
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.

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.
Does the oort cloud have an atmosphere?
The Oort Cloud is a region in space, predominantly composed of icy debris, located at the outer edge of our solar system. It does not have an atmosphere as it consists of loosely bound icy objects and comets that are mostly influenced by the gravitational interactions with nearby celestial objects, such as the sun and passing stars.
What number is halfway between 16 and 90?
Well, honey, the number halfway between 16 and 90 is 53. Technically correct, but let's be real, you could have figured that out with a calculator faster than it took you to ask me. Now go on and enjoy that middle-of-the-road number like the math whiz you are.
What is the area of science that involves the study of planets and outer space?
Astronomy is the area of science that involves the study of planets, stars, galaxies, and other celestial bodies in outer space. It encompasses a wide range of topics including the origins of the universe, the structure of galaxies, and the behavior of celestial objects.
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
How many contants is there in space?
Space is vast and infinite, containing an estimated 100 billion galaxies, each with billions of stars. It also contains various celestial objects such as planets, asteroids, comets, and nebulae. The exact number of objects in space is unknown but it is incredibly vast.
What is a Messier Object?
A Messier object is any celestial object listed in the Messier catalog, which is a compilation of astronomical objects such as galaxies, nebulae, and star clusters. The catalog was created by French astronomer Charles Messier in the 18th century to help distinguish these objects from comets.
