Brainliest and 5 full stars and 30 points asap.

an unlabeled hierarchical diagram of various astronomical bodies is shown below. the labels a, b, c, and d can be used to represent the milky way, universe, planets, clusters, and stars.

an image of four circles nestled one within the other is shown. the lower boundary of all four circles touch one another. the largest and the outermost circle is labeled a. the next circle in order is labeled b. the next circle is labeled c. the innermost circle is labeled d.

part 1: which four astronomical bodies would you choose to represent the four labels in the diagram?

part 2: justify your choice based on the hierarchical relationships in astronomical bodies.

Part 1 Answer

A: Universe

B: Milky Way

C: Clusters

D: Planets

Part 2 Answer

The universe is the entire cosmic spectrum of all matter and all things. It includes everything else -- galaxies, star clusters, stars, planets. Therefore, it's A.

The Milky Way is a galaxy -- a system of stars and interstellar matter. Therefore, it is B, because it contains all of the below.

Inside the galaxy are C and D.

C is the cluster: an assembly of stars held together by the mutual gravity of everything inside.

And inside the cluster will be D: any planets that are also inside clusters, which also reside in a Galaxy, which resides inside the universe.

As accurately described by Einstein's theory of relativity, gravity is not necessarily a force, but a consequence of the curvature of space time that is caused by the uneven distribution of mass. But this could be understood more easily through Newton's Law of Universal Motion. The equation is shown below:

F = G(m₁m₂/d²), where
F is the gravitational force
G is called Newton's universal gravitation constant equal to 6.673×10⁻¹¹ N m² kg⁻²
m is the mass of the objects 1
d is the distance between the objects
 
Basing on the equation, the gravitational force depends on the mass the distance between the objects. So, when you compare the gravitational pull between Earth and moon. you do not need to include the effect of distance because, together. they have the same amount of d. So, it mainly depends on the masses. Since F is directly proportional to m, the greater the mass, the greater is the pull.

So, the answer is: The Earth has more mass than the moon.
