What Star is Bigger than Ton 618?

Have you ever wondered about the celestial giants that outshine Ton 618? Ton 618, also known as HD 140283, is a star located in the constellation of Lyra. It’s a well-known star due to its high luminosity and its proximity to Earth. But what about the stars that dwarf Ton 618 in size and brightness? Let’s dive into the cosmos and explore the wonders of the universe.

Understanding Ton 618

Before we embark on our journey to find stars bigger than Ton 618, let’s take a moment to understand the star itself. Ton 618 is a red giant star, which means it has exhausted the hydrogen in its core and is now burning helium. It has a radius about 50 times that of the Sun and a luminosity about 1,000 times greater. Its surface temperature is around 3,500 Kelvin, making it a relatively cool star compared to other red giants.

The Search for Bigger Stars

Now that we have a grasp on Ton 618, let’s search for stars that surpass it in size and brightness. One such star is UY Scuti, a red supergiant located in the constellation of Scutum. UY Scuti is the largest known star by volume, with a radius estimated to be around 1,700 times that of the Sun. Its luminosity is about 10,000 times greater than our Sun, making it one of the most luminous stars in the universe.

Another star that outshines Ton 618 is VY Canis Majoris, a red supergiant located in the constellation of Canis Major. VY Canis Majoris has a radius estimated to be around 1,800 times that of the Sun, making it one of the largest stars known. Its luminosity is about 10,000 times greater than our Sun, similar to UY Scuti.

Comparing the Stars

Star	Radius (Solar Radii)	Luminosity (Solar Luminosities)	Temperature (Kelvin)
Ton 618 (HD 140283)	50	1,000	3,500
UY Scuti	1,700	10,000	3,500
VY Canis Majoris	1,800	10,000	3,500

As you can see from the table, UY Scuti and VY Canis Majoris are both significantly larger and more luminous than Ton 618. Despite having similar surface temperatures, their sizes and luminosities are on a whole different scale.

Other Notable Stars

While UY Scuti and VY Canis Majoris are the most prominent stars larger than Ton 618, there are other notable stars worth mentioning. One such star is Betelgeuse, a red supergiant located in the constellation of Orion. Betelgeuse has a radius estimated to be around 1,000 times that of the Sun, making it one of the largest stars in the Milky Way. Its luminosity is about 100,000 times greater than our Sun, which is even more impressive than UY Scuti and VY Canis Majoris.

Another star worth mentioning is Antares, a red supergiant located in the constellation of Scorpius. Antares has a radius estimated to be around 1,100 times that of the Sun, making it one of the largest stars in the sky. Its luminosity is about 30,000 times greater than our Sun, which is still significantly larger than Ton 618.

Conclusion

The universe is filled with wonders, and stars like UY Scuti, VY Canis Majoris, Betelgeuse, and Antares are just a few examples of the celestial giants that dwarf Ton 618 in size and brightness.
