Here's a breakdown of the process:
* Stage 1: Giant Molecular Cloud Collapse (100,000 years): It all began with a giant cloud of gas and dust, mostly hydrogen and helium, collapsing under its own gravity.
* Stage 2: Accretion Disk Formation (1 million years): As the cloud collapsed, it started rotating faster and flattened into a disk, with a hot, dense core forming at the center.
* Stage 3: Protostar Formation (100,000 years): The core continued to collapse, growing hotter and denser until it ignited nuclear fusion, officially becoming a protostar.
* Stage 4: T-Tauri Phase (10 million years): The protostar, now with a powerful outflow of material, gradually calmed down as it continued to grow in mass, eventually reaching a stable state.
* Stage 5: Main Sequence Star (10 billion years): The Sun reached the stage where it is today, fusing hydrogen into helium in its core.
This process is a simplification, of course, and there were many complex events and fluctuations along the way. However, it gives you a general idea of the timeline and the key stages involved in the Sun's formation.
