Sun | Definition, Composition & Solar Surface Lesson Additional Info Author Meaghann Stoelting View bio Instructor David Wood View bio What is the sun made of? Learn about the surface of the sun, what it looks like, does the sun have a solid surface, and the name of the surface...
Definition The protosun composition is the initial composition of the giant molecular cloud , from which the solar system has formed (sun and protoplanetary disk). This composition consists of about 70.5 % hydrogen, 27.5 % helium, and 2 % of heavier elements. See Also Molecular Cloud ...
Although the solar system definition might seem simple, understanding the components, the structure, and the formation of a solar system is no simple task. For the remainder of this lesson, we will focus on our own solar system, meaning the sun-planet-moon system in which we live. But ...
To understand the relationship between our bacterial microbiome and health, it is essential to define the microbiome in the absence of disease. The digestive tract includes diverse habitats and hosts the human body's greatest bacterial density. We descri
Patterns in relative elemental abundance of the Solar System, Earth’s lithosphere, and soils are best understood when abundance is plotted as a function of atomic number Z. Astronomers believe that the composition of the Sun’s photosphere is a good representation of the primordial gas and dust...

The light stable isotope compositions of meteorites, planets, and the Sun constrain how our solar system formed and the nature of the formation environment. Given that the protosun was the primary mass of the nascent solar system, its isotopic composition is of particular importance. The NASA Gen...

In total, there areeightplanets in our solar system. The definition of theinner planets, also known as theterrestrial planets, are the four that are closest to the Sun. These inner planets all have some common characteristics that separate them from the other four. ...
Atoms are made of three main parts: protons, neutrons and electrons. Protons and neutrons are contained inside the very center of the atom, which is called the nucleus. Electrons orbit around the outside of the nucleus, similar to how the Earth orbits the sun. Read Atom | Definition, ...
