Is the sun a young star?
Yes, the sun is considered a middle-aged star, around 4.6 billion years old. It is classified as a main-sequence star in the later stages of its life cycle.
Is Vega on the main sequence?
No, Vega is a main-sequence star, meaning it is currently fusing hydrogen into helium in its core. The star is relatively young compared to our Sun, so it still has a long life ahead of it on the main sequence.
A big ball of hot gases in space is called what?
A big ball of hot gases in space is called a star.
What is a group of stars that form when a lot of gases and dust come together?
A group of stars that form when a lot of gases and dust come together is called a star cluster. Star clusters can be either open clusters, which are loosely bound and contain young stars, or globular clusters, which are tightly bound and contain older stars.
What distinguishes a nebula and a star?
A nebula is a cloud of substances and gases that can form into a star. A star is a ball of hydrogen and helium with trace amounts of other gases. A supernova is the death of a star.
What gases make the main sequence star?
Hydrogen and Helium
What are the main gases if a star?
Hydrogen and helium
What are The three main gases of a star?
Dance because its my favorite
What two gases are a main sequence star made of?
Hydrogen and helium
What old-main-sequence star will be composed of a higher percentage of helium than a young main-sequene star?
All of them, that's how a star gets to be "old" ... it converts its hydrogen into helium.
What is the main predictor of where a star will spend most of the time on the main sequence and why?
The star's mass. More mass will make the star hotter, and will increase the pressure in the center; this will make the star burn its fuel faster.When a star is on the "main sequence", it burns hydrogen-1, converting it into helium-4.
Is the sun a young star?
Yes, the sun is considered a middle-aged star, around 4.6 billion years old. It is classified as a main-sequence star in the later stages of its life cycle.
When does a protostar becomes a main sequence star?
As the gases in a protostar begin to collapse, the central core begins to heat up due to pressure. As more gases are absorbed, the greater the pressure. Once the temperature of the core reaches 10 million degrees K, hydrogen fusion begins, and the star begins it's life on the main sequence. The star will stay on the main sequence whilst it still has hydrogen to fuse. Once all the hydrogen has been used, the star will drop out of the main sequence. Protostar stage in the stellar evolution. [See related question]
What gases make up the star denebola?
Wikipedia lists it as a main sequence star. That means that it still has significant amounts of hydrogen. Main sequence stars also typically have a smaller amount of helium (remember, the hydrogen gradually converts to helium), and even smaller amounts of the so-called "metals" (i.e., all other elements).
What force make a star?
All of the forces act to make a star. Gravity is the main force, which pulls everything together, and the other forces ignite the star.
How is the moon not a star?
The Moon is not a star because a star is made of a gases.
Is Vega on the main sequence?
No, Vega is a main-sequence star, meaning it is currently fusing hydrogen into helium in its core. The star is relatively young compared to our Sun, so it still has a long life ahead of it on the main sequence.
