If you could take the Sun apart, and stack up its various elements, you would find that the Sun is made of hydrogen (74%) and helium (about 24%). Astronomers consider anything heavier than helium to be a metal. The remaining amount of the Sun is made of iron, nickel, oxygen, silico...
Just like most other stars, the sun is made up mostly of hydrogen, followed by helium. Nearly all the remaining matter consists of seven other elements — oxygen, carbon, neon, nitrogen, magnesium, iron and silicon. For every 1 million atoms of hydrogen in the sun, there are 98,000 of...
What is it made of? Neptune is made of rock and metal in thecore. The core is probably bigger than Uranus's because Neptune weighs more, but is the same size. Around the core is rock, water,ammoniaandmethane. The atmosphere is made ofhydrogenandhelium. Lower down in the atmosphere, th...
“A direct measure of solar activity is the number of sunspots on the surface,” Reinhold said. “Finding such stars with very similar parameters as our sun but being five times more variable was surprising.” The sun —made up mainly of hydrogen and helium—is an average-sized star that ...
Saturn is made mostly of hydrogen and helium(氦) gas. Saturn is about 74,898 miles in diameter(at the equator). This is about 9.4 times the diameter of the Earth. 764 Earths could fit inside a hollowed-out Saturn. Saturn is the most oblate planet in our solar system. It has a ...
The sun – made up mainly of hydrogen and helium – is an average-sized star that formed more than 4.5 billion years ago. It stretches about 1.4 million kilometers across and has a surface temperature of 5,500 degrees Celsius. 太阳形成于45亿年前主要由氢和氦组成,其大小处于恒星界的平均水平...
What 2 things are the Sun mostly made of? The Sun is a huge, glowing sphere of hot gas. Most of this gas ishydrogen(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...
This is why the outer planets consist mostly of hydrogen, helium and other light elements, and the inner planets are made of heavier elements like iron, sulfur and silicon, Manuel says. Strange xenon came from the helium-rich outer layers of the supernova, while normal xenon came from its ...
