The sun is a star, fusing hydrogen atoms in its inner most layers to produce electromagnetic energy. A Protostar is basically a clump of interstellar matter/dust that may be coalescing due to gravitation to form a star but its center has not yet achieved a high enough temperature for hydrogen fusion to begin.
What else can I help you with?
Was the Sun a protostar about a million years ago?
No. The sun was a protostar about 4.6 billion years ago.
Is the sun a protostar?
No, the sun is not a protostar. It is a mature star that is in the main sequence phase of its life cycle, where it fuses hydrogen into helium in its core. A protostar is a young star that is still in the process of accumulating mass and contracting before it begins hydrogen fusion in its core.
What is the temperature of a protostar?
the color of the protostar is red
How far is a protostar away from the sun?
A protostar is a star in its early stages of formation. These can exist almost anywhere in the galaxy, and so the fact that a protostar is identified in and of itself is not enough information to define how far away it is from our sun. Protostars can be aged, however, based on their luminescence and size, which is determined based on the wavelength of energy being emitted from their core.
Was the earth formed from a protostar?
No, the Earth formed from gas and dust in the solar nebula that surrounded the young Sun. The protostar is the early stage of a star's formation, while the Earth's formation was part of the process that created the entire solar system.
What is a round sphere that does not give off a light of its own?
A planet.Planets do not generate their own light; they reflect the light of the Sun.
The earliest stage of a stars life is called a?
A Protostar.
What is the star life cycle of the sun?
Life cycle of a sun like star. A sun like star will start out as a nebula to a protostar to a main sequence star to a red giant and into a white dwarf and will simply fade out.
How was your solar system created?
4.5 years ago once the sun condensed into a protostar it started pulling in rocks and forming planets
What was the early form of the sun called?
Before becomming a main sequence star, our sun would have been a protostar. A protostar is where there is a large gathering of contracting gas. Matter falls into a central condensation, when the surrounding gas/dust envelope disperses and the accretion process stops, the star moves towards becoming a main sequence star.
What stages has the sun went through?
The sun has already gone through the stage of protostar. It was the condensing stage from a huge cloud of gas and dust, heating up and making some light.
Are protostar a star?
A protostar is more like a stage previous to a star - before it ignites.
