Written Assignment #5 The structure of the Sun is defined by the conditions of energy conservation, mass conservation, momentum conservation and the mode of energy transport. The Sun has many layers. The interior of the Sun includes the core, the radiative zone, and the convective zone. The photosphere produces the visible light we see, the chromosphere is the part of the solar atmosphere, and the corona is the outermost layer of the Sun. The sunspots are regions on the surface of the Sun. They seem darker because they are cooler than the surrounding photosphere. Sunspots affect human activities. It was found that during the sunspot maximum, the movement of humans is also at its peak (Sunspots and Human Behavior).
The majority of the stars in our galaxy are main sequence stars. Main sequence stars are actively fusing hydrogen into helium in the middle (The Main Sequence).
They are characterized by the source of the energy and are unchanging for long periods of time. Stars are classified by their spectra and temperature. As stars begin to die, they become giants and supergiants. Smaller start become white dwarfs, which are below the main sequence.
They will then eventually become cold black dwarfs. Dwarfs are relatively small stars, while giants are old and large stars. Black hole is a region in the space, where gravitational field is so strong that the light cannot escape its pull after it has fallen past its event horizon. Jovian planets are larger than the terrestrials. All terrestrials are metallic and rocky worlds with an aggregate average density approximately 5 times that of liquid water, while the Jovian planets have very low densities (Terrestrial and Jovian: The Two Types of Major Planetary Bodies ).

The Jovian planets have approximately the same chemical composition as the Sun, while the terrestrials hav very little helium and hydrogen and are composed mostly of much heavier elements. The terrestrials have weaker magnetic fields than the jovians do. In contrast to jovians, the terrestrials have almost no natural satellites.
The jovians rotate more rapidly than the terrestrials do. Finally, all jovian planets are farther from the Sun than the terrestrial planets are. The terrestrial planets are: Terrestrials: Mercury (the closest planet to the Sun and the eighth largest), Venus (is the second planet from the Sun and the sixth largest. It is named Venus because it is the brightest of the planets known to the ancients. This planet is also sometimes regarded as Earth’s sister planet), Earth (the third planet from the Sun and the fifth largest. It has only one natural satellite, the Moon), Mars (the fourth planet from the Sun and the seventh largest. It is called Mars, the god of War due to its red color), Earth’s Moon (it is the only natural satellite of Earth.
It is the only extraterrestrial body to have been visited by humans).
Jovian planets are: Jupiter (it is more than twice as massive as all the other planets combined), Saturn (the sixth planet from the Sun and the second largest planet), Uranus (it is larger in diameter but smaller in mass than Neptune), and Neptune (the eighth planet from the Sun and the fourth largest planet).
