what are some characteristics of the sun?
535915
Characteristics. The Sun consists of about 70% Hydrogen, 28% Helium and 2% of metals such as iron. Other characteristics are its rotation, temperature, and radiation.

Astronomers classify stars according to their physical characteristics. Characteristics used to classify stars include color, temperature, size, composition, and brightness. Stars vary in their chemical composition.

Our Sun is 864,000 miles in diameter and 10,000 degrees Fahrenheit on the surface. Our Sun is a bright, hot ball of hydrogen and helium at the center of our solar system. It is 864,000 miles (1,392,000 km) in diameter, which makes it 109 times wider than Earth.

The Sun is found on the main sequence with a luminosity of 1 and a temperature of around 5,400 Kelvin. Astronomers generally use the HR diagram to either summarise the evolution of stars, or to investigate the properties of a collection of stars.

['Two protons within the Sun fuse. ... ', 'A third proton collides with the formed deuterium. ... ', 'Two helium-3 nuclei collide, creating a helium-4 nucleus plus two extra protons that escape as two hydrogen.']

The main part of the Sun has three layers: the core, the radiative zone, and the convection zone. The Sun's atmosphere also has three layers: the photosphere, the chromosphere, and the corona. Nuclear fusion of hydrogen in the core of the Sun produces tremendous amounts of energy that radiate out from the Sun.

The Sun is a huge, glowing sphere of hot gas. Most of this gas is hydrogen (about 70%) and helium (about 28%). Carbon, nitrogen and oxygen make up 1.5% and the other 0.5% is made up of small amounts of many other elements such as neon, iron, silicon, magnesium and sulfur.

The Sun is a 99.9997% perfect sphere. Hmmm. Put another way, if you shrank the Sun to the size of a basketball, the equatorial diameter would be wider than the polar one by about 0.4 microns - the width of a human hairless than the size of an average bacterium!

Reflective surfaces can deliver high solar reflectance (the ability to reflect the visible, infrared and ultraviolet wavelengths of the sun, reducing heat transfer to the surface) and high thermal emittance (the ability to radiate absorbed, or non-reflected, solar energy).
1181708
The sun is mostly composed of the elements hydrogen (H) and helium (He). By mass the composition of the sun is 75 percent hydrogen and 25 percent helium. Various metals make up less than 0.1 percent of the mass of the sun.

Scientists who study the Sun usually divide it up into three main regions: the Sun's interior, the solar atmosphere, and the visible "surface" of the Sun which lies between the interior and the atmosphere. There are three main parts to the Sun's interior: the core, the radiative zone, and the convective zone.

The physical characteristics of the Earth include its size and composition. The Earth also has gravity and magnetic force fields. Physical characteristics include shape, size and composition. Just as the Sun and Moon appear as spheres, so too is the Earth spherical in shape.

Characteristics of Echinoderms Echinoderms are characterized by radial symmetry, several arms (5 or more, mostly grouped 2 left - 1 middle - 2 right) radiating from a central body (= pentamerous). The body actually consists of five equal segments, each containing a duplicate set of various internal organs.
