~Astronomy Ranking Task Homework~
Size & Scale
Exercise #1
Largest to Smallest: E (Nebula), F (The Solar System), B (The Sun), C (Jupiter), G (Earth), I (Mars), D (The Moon), A (Pluto), and H (Neutron Star)
A nebula is bigger than the Solar System; Solar System makes all the planets and the Sun; the Sun is larger than Jupiter and so on.
Largest to Smallest: Largest to Smallest: E (Nebula), F (The Solar System), B (The Sun), C (Jupiter), G (Earth), I (Mars), D (The Moon), A (Pluto), and H (Neutron Star)
The reason for the ranking of the astronomical objects in the manner due to the sizes of the planets based on the order by mass; furthermore, the nebula has more mass than any other objects and the Sun makes up the majority of the mass based on the Solar System. Also, the Sun is a part of the Solar System which makes the Solar System which is quite bigger than the Sun. (Course Hero)
Exercise #2
Largest to Smallest: G (Galaxy Cluster), D (Andromeda Galaxy), B (Globular Cluster), F (Nebula), A (The Solar System), E (The Sun), and C (Neutron Star)
Galaxy Clusters have many Galaxies. The Andromeda Galaxy is made up of stars and planets based on the Galaxy. The Globular Cluster is made up of stars close together. Nebula are gases and dusts which collects together based on the form within the galaxy. Then the Solar System since rest of the Planets is bigger than a Nebula Star. Next, is the Sun, and lastly, the Neutron Star. (Course Hero)
Exercise #3
Largest to Smallest: I (Galaxy Center), C (Spiral Galaxy), J (Globular Cluster), G (Giant Star), H (Nebula), B (The Sun), A (Jupiter),E (White Dwarf),D (Neutron Stars),F (Black Holes)
The Solution:
1.Galaxy Cluster: About 100 to 1000 Galaxies in a cluster are present.
2. Spiral Galaxy: Spiral galaxies are present on the edges of clusters.
3.Globular Cluster: Few ten thousand to few hundred thousand stars are present in one Globular cluster.
4.Giant star: 100 million to 1billion kilo meters in diameter
5.Nebula: About 150million kilometers in size
6.The Sun: The radius of sun is 695,510km
7.Jupiter: Jupiter has mean radius of 69911km
8.White Dwarf: Volume nearly equal to earth
9.Neutron Stars: Radius of neutron star is about 10km
10.Black Holes: (1mile) Now black holes are having different sizes, it’s size ranges from 1miles to the size of solar system which is 11billion miles.... I ranked black hole according to the Lowe's size. If you rank black hole with respect to its largest radius from event horizon, then it's rank would be number 4 after Globular cluster.
