What Stage Of Life Is Our Sun In?

What are the stages of a star’s life?

Seven Main Stages of a StarGiant Gas Cloud.

A star originates from a large cloud of gas.

Protostar.

When the gas particles in the molecular cloud run into each other, heat energy is produced.

T-Tauri Phase.

Main Sequence.

Red Giant.

What are the three stages of the sun’s life?

And like all stars, it has a lifespan, characterized by a formation, main sequence, and eventual death. This lifespan began roughly 4.6 billion years ago, and will continue for about another 4.5 – 5.5 billion years, when it will deplete its supply of hydrogen, helium, and collapse into a white dwarf.

What color star is hottest?

Blue starsWhite stars are hotter than red and yellow. Blue stars are the hottest stars of all.

Is a red giant hotter than the sun?

A red giant is not very hot at its surface, but its core may reach 1 billion degrees Celsius (that’s 100 times hotter than the sun) (Dickin, 2005).

Will our Sun become a black hole?

Will the Sun become a black hole? No, it’s too small for that! The Sun would need to be about 20 times more massive to end its life as a black hole. … In about 5 billion years, the Sun will start to run out of hydrogen in its core to fuse, and it will begin to collapse.

What stage of life is the Sun currently in?

The Sun is currently a main sequence star and will remain so for another 4-5 billion years. It will then expand and cool to become a red giant, after which it will shrink and heat up again to become a white dwarf. The white dwarf star will run out of nuclear fuel and slowly cool down over many billions of years.

How old is our sun and when will it die?

The Sun is about 4.6 billion years old – gauged on the age of other objects in the Solar System that formed around the same time. And, based on observations of other stars, astronomers predict it will reach the end of its life in about another 10 billion years.

How long does a star take to die?

Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. The most massive stars can burn out and explode in a supernova after only a few million years of fusion. A star with a mass like the Sun, on the other hand, can continue fusing hydrogen for about 10 billion years.

What is the final stage of a star?

A planetary nebula is the final stage of a Sun-like star. As such, planetary nebulas allow us a glimpse into the future of our own solar system. A star like our Sun will, at the end of its life, transform into a red giant.

What is the second stage of a star’s life?

Protostar. A protostar is the second stage of a star’s life cycle which is formed when a region of condensing matter begins to heat up as a result of the force of gravity.

What is the biggest star in the universe?

The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun. And it’s not alone in dwarfing Earth’s dominant star.

Is our sun a red giant?

In approximately 5 billion years, the sun will begin the helium-burning process, turning into a red giant star. When it expands, its outer layers will consume Mercury and Venus, and reach Earth. … The changing sun may provide hope to other planets, however.
