How Big Can Stars Get? Exploring the Universe's Enormous Celestial Bodies

🌟The largest observed star, wG64, has an estimated radius of 1,540 times that of the Sun.

💫The size of a star depends on several factors, including mass, composition, evolutionary history, and stellar wind.

👉Stevenson 2-18, previously believed to be the largest star, may have been overestimated in size.

✨There is a theoretical limit to how big stars can grow, estimated to be around 1,500 times the radius of the Sun.

🔭Advancements in observational techniques and technology will continue to refine measurements and our understanding of these gigantic celestial bodies.
