What is a star's main fuel during its lifetime?
A star's main fuel during its lifetime is hydrogen. Through nuclear fusion processes in the star's core, hydrogen is converted into helium, releasing vast amounts of energy in the form of light and heat. This fusion process sustains the star's energy output and keeps it shining bright.
A star's lifetime depends on what?
A star's lifetime depends on its mass. More massive stars have shorter lifetimes, burning through their fuel faster, while less massive stars have longer lifetimes. Additionally, the composition of a star determines how it burns its fuel and influences its lifetime.
Protostar will turn into what kind of star?
Protostars will eventually evolve into main sequence stars, where they will spend the majority of their lifetime fusing hydrogen into helium in their cores. The exact path of evolution will depend on factors such as mass, temperature, and composition.
How does the main-sequence lifetime of a star compare to its entire fusion lifetime?
The main-sequence lifetime is a phase in a star's life when it fuses hydrogen into helium in its core. This phase typically lasts about 90% of a star's total fusion lifetime. After the main sequence, a star may continue to fuse other elements, depending on its mass, which will determine the total duration of its fusion lifetime.
What determines how long a star will live?
Kinds of 'fuel' and the mass and the stars determines how it dies. If it is large enough, it will create a Neutron Star or a Black Hole; if it is some size close to our sun, it will become dwarf planets.

How is the lifetime of a star comparable to stellar evolution?
Stellar evolution is the term for the changes a star undergoes during its lifetime.
What percentage of a star's total lifetime is spent on the main sequence?
Roughly 90% of a star's total lifetime is spent on the main sequence, where it fuses hydrogen into helium in its core. After this stage, the star will evolve off the main sequence and follow a different path, such as becoming a red giant or a supernova.
How does a star's mass indicate lifetime?
When a star is at the end of its lifetime its mass increases.
What is a star's main fuel during its lifetime?
A star's main fuel during its lifetime is hydrogen. Through nuclear fusion processes in the star's core, hydrogen is converted into helium, releasing vast amounts of energy in the form of light and heat. This fusion process sustains the star's energy output and keeps it shining bright.
A star's lifetime depends on what?

What determines a plants orbit?
A plant's orbit is determined by the gravitational pull of the star or body it is orbiting, as well as its own velocity. The balance between the pull of gravity and the speed of the plant determines its orbital path.
What are 3 physical features that change during the life of a star?
Within the lifetime of a star, its colour, its size, and the amount of heat it radiates will all change.

What determines color of the stars?
The temperature determines the color of the star!:)
What two factors determine the life cycle path of a star?
The two factors that determine the life cycle path of a star are its mass and composition. A star's mass dictates how it will evolve over time, while its composition affects its energy production and how it will eventually end its life cycle.
What determines if a star will be a white dwarf or neutron star?
Its Mass.
