How long did it take for the sun to form?

Question

Christopher Ales · Accepted Answer

It took about 50 million years for the Sun to form.

Stars are formed from hydrogen and helium-dominated disks that begin to collapse due to gravity. It takes millions of years for the protostar's core pressure and temperature to rise to a point where hydrogen fusion can begin. For stars like our Sun, the process of raising the temperature and pressure to the point where hydrogen fusion occurs takes around 50 million years.

I don't think there is an accurate answer.

We note that it occurs, but at a pace too slow to quantify on human timescales; a reasonable estimate would likely be in the range of many millions, but not billions of years.

undefined The sun formed approximately 4.6 billion years ago through the gravitational collapse of a region within a large molecular cloud. This process, known as stellar formation, likely took several million years to complete.

Alexander Acosta · Answer

undefined The Sun formed about 4.6 billion years ago. It began as a large cloud of gas and dust known as a nebula, which collapsed under its own gravity. As the material in the center became more concentrated, it heated up and eventually ignited nuclear fusion reactions, becoming the Sun. This process took approximately 50 million years from the initial collapse of the nebula to the ignition of fusion in the core.
