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.
How do you measure the distance between two heavenly bodies?
Let's say we want to measure the distance between objects A and B. First, we measure the distance from the Earth(point E) to these objects(using Doppler-shifts).Then, we measure the angle AEB.We now know the lengths of two sides, and the angle between them. That's how we find the distance AB.
How can you find the force between objects that are any distnace apart?
You can find the force between objects that are any distance apart by using the formula for the gravitational force, which is F = G * (m1 * m2) / r^2, where G is the universal gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers. This formula describes the attractive force between any two objects in the universe.
How do you find the speed of a moving object?
By measuring the distance and time
Why does a topographic map have a key?
the key explains what the colors and shapes on the map represent. It also has a scale so you can accurately find the distance between objects.
How do you find the distance between 5 cities?
First, you have to specify what cities you want to find the distance between, and then you can find the distance between each one, and finally add all the distance together, to give you the total.
How do you find the average speed of a moving object?
Divide the distance travelled by the time.
How do you find the force of gravitational attraction?
The force of gravitational attraction between two objects is calculated using Newton's law of universal gravitation: F = (G * m1 * m2) / r^2, where F is the force, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between the centers of the objects.

How do you find objects speed?
The speed of an object can be found by dividing the distance travelled by the object by the time taken for the object to travel that distance. Speed=Distance/Time
