Bernard's star has a mass of how many times the mass of sun?
15-17 percent of the mass of the Sun.15-17 percent of the mass of the Sun.15-17 percent of the mass of the Sun.15-17 percent of the mass of the Sun.
How does the amount of Hydrogen differ from that of helium in the Sun mass?
The Sun is about 70% hydrogen, 28% helium, and 2% "other". When the Sun gets to about 50% hydrogen, the amount of helium present will seriously interfere with the hydrogen fusion, and the Sun will begin to collapse under its own gravity. The Sun's core is currently around 15 million degrees Kelvin. As the Sun collapses, the increasing pressure will heat the Sun, and when it gets to about 45 million degrees, the Sun will begin fusing helium and with the new power source will expand into a red giant. We expect this to happen in about 4 billion years, perhaps a little more.
Why does your sun have 2 percent heavier elements and from where do they come?
I think it's our Sun which gets heavier elements from fusion of hydrogen and other light elements.Edit: Our Sun does create helium from hydrogen by fusion, but that's all. The reason it has heavier elements is that these come from the nebula that formed the Sun. The heavier elements are thought to have come from stars that exploded as "supernovas", a long time ago.
What intrusive igneous rock is composed of 18 percent olvine 48 percent pyroxene and 34 percent plagioclase?
Gabbro is made of these minerals. The proportions can vary.
What is the name of the main elements of the Sun's composition and their relative abundance?
hydrogen and helium... i think and lots of it
What percentage of the Sun is composed of helium?
The sun in composed of 25 percent helium. The other 75 percent is hydrogen. The sun also has small amounts of other elements such as neon, oxygen, carbon, and magnesium.
What percent of the sun is made of helium?
At the moment about 24% but it is increasing every second.
Is the sun composed of nitrogen and helium?
Nitrogen is present in the sun in very small amounts. The sun is over 90% hydrogen and about 9% helium.
What two gases make up more than 90 percent of the sun?
The sun is primarily composed of hydrogen and helium, which together make up more than 90 percent of its mass. Hydrogen accounts for about 74 percent, while helium makes up approximately 24 percent. These two gases are crucial for the nuclear fusion processes that power the sun.
What is the sun composed of mainly?
The sun is composed of about 73% Hydrogen, 25% Helium, and 2% Oxygen... This means that the sun is mainly composed of Hydrogen
What percent of hydrogen is fused to helium in the sun and what percent is fused to energy?
99.993 % into Helium, .007 % into energy.
What is then sun made of?
The sun is mainly composed of hydrogen and helium gas. These elements undergo nuclear fusion in the sun's core, converting hydrogen into helium and releasing immense amounts of energy in the form of light and heat.
What is the sun composition of the sun?
The Sun is composed of about 24.85% Helium. Near enough not to worry as a fourth.
What is a composition of the Sun?
The Sun is composed of about 24.85% Helium. Near enough not to worry as a fourth.
What is the composite of the sun?
The Sun is composed of about 24.85% Helium. Near enough not to worry as a fourth.
What is the surface composition of the sun?
It is composed of superheated hydrogen and helium plasma.
What are the percentages of helium and hydrogen that compose the sun?
The sun is about 98 percent hydrogen.
