These gases are actually in the form of plasma. It is the dominant body of the system, constituting more than 99 percent of its entire mass. The Spectra of the Sun. Composition of the Solar System. CHEMICAL GEOLOGY --- ISOTOPE GEOSCIENCE ELSEVIER Chemical Geology 120 (1995) 223-253 The composition of the Earth' W.F. Sun – The sun is a star about 330,000 times the size of the earth. Joseph Fraunhofer. For example, sodium lines as observed in the sun’s spectrum means that the sun’s atmosphere contains some sodiums atoms. The Sun is the source of an enormous amount of energy, a portion of which provides Earth with … Located at the centre of the solar system and influencing the motion of all the other bodies through its gravitational force is the Sun, which in itself contains more than 99 percent of the mass of the system. It turns out that the Sun contains the same elements as Earth but not in the same proportions. In her 1925 Ph.D. thesis work, Cecilia Payne invented modern methods of interpreting spectra of the sun and stars. The Sun's extremely hot outer layer, the corona, has a very different chemical composition from the cooler inner layers, but the reason for this has puzzled scientists for decades. This means the particles have an increased or reduced number of electrons. From there, the Sun orbits the center of the Milky Way Galaxy, bringing the planets, asteroids, comets and other objects along with it. Composition of the Sun’s Atmosphere. Ever since Newton showed that sunlight is a mixture of all colors, scientists have studied the Sun's spectrum. Find out more about composition of the Sun, Earth and Moon! Sun, star around which Earth and the other components of the solar system revolve. It is composed of about ¾ hydrogen and ¼ helium, with a small percentage of other, heavier elements. About 73% of the Sun’s mass is hydrogen, and another 25% is helium. The composition of the sun is 71% hydrogen, 27.1% helium and less than 2% of all other elements. As explained in Radiation and Spectra, we can use a star’s absorption line spectrum to determine what elements are present. Let’s begin by asking what the solar atmosphere is made of. In this review, we evaluate the current understanding of the solar photospheric composition. Because the Earth moves about 1 /12 of the way around the Sun while the Sun makes one rotation, the synodic period is somewhat greater than the period that would be observed … Solar spectrum showing the dark absorption lines. The solar chemical composition is an important ingredient in our understanding of the formation, structure, and evolution of both the Sun and our Solar System. The Sun's Composition. More specifically, our Sun is in a spiral arm called the Orion Spur that extends outward from the Sagittarius arm. Composition The sun is made up of a blazing combination of gases. The Sun, and everything that orbits it, is located in the Milky Way galaxy. McDonough"', S.-s.

Escape velocity = 618 km/s * The Sun’s rotational period as observed from Earth is known as the synodic period . The center temperature is modeled to be 15.5 million K. The Sun is fueled by the proton cycle of nuclear fusion. Deep in its core, the sun is extremely dense and hot, with temperature reaching over 15 million degrees Kelvin.
