How big is WOH G64?

WOH G64 is 2.1 terameter

The Universe’s Giant: WOH G64

Have you ever wondered what it would be like to live on a planet orbiting a star that’s so enormous it makes our own sun look like a tiny speck? Welcome to the world of WOH G64, a red supergiant star that sits in the Large Magellanic Cloud, a satellite galaxy not too far away from our own Milky Way. This star is a real heavyweight, shining with a light that’s about 282,000 times brighter than our Sun.

Size Matters: Comparing WOH G64 to Known Objects

Let’s put this into perspective. How does WOH G64 fare when compared to objects we know?

  • If we compare it to our Sun, WOH G64’s radius is about 1,540 times bigger. That’s like comparing a basketball to a tiny grain of sand. - And if we were to place WOH G64 at the center of our Solar System? It’s so gigantic that its surface would extend past the orbit of Jupiter! That’s right, it would swallow up Mercury, Venus, Earth, Mars, and even the giant Jupiter. - To give you an even better idea, if we spread out its dust envelope, it would cover a distance of roughly one light year. That’s about 5.88 trillion miles!

More Than Just Size: WOH G64’s Luminosity

WOH G64 isn’t just impressive in size, it’s also one of the most luminous stars we know of. Its luminosity, or total amount of energy it emits per unit of time, is around 282,000 times greater than that of our Sun. Imagine the Sun’s brightness, and then multiply that by 282,000.

The Surrounding Dust Envelope

One of the fascinating features of WOH G64 is its dust envelope, which is so thick it obscures the star to some extent. This dust envelope is made of material that the star has expelled, and it contains between 3 to 9 times the mass of our Sun. This material was created by the powerful stellar wind, a stream of charged particles that stars like WOH G64 emit.

Conclusion: A Star Worth Studying

WOH G64 is a fascinating object, not just because of its enormous size, but also due to its extreme luminosity and intriguing dust envelope. It’s a perfect example of how diverse and awe-inspiring the universe can be. And who knows? Perhaps one day, we might even find planets orbiting this cosmic giant. Until then, we can only gaze upon WOH G64 in wonder, appreciating its place in the vast cosmos.

Smaller By Category
VY Canis Majoris
VY Canis Majoris is one of the largest known stars. It is so large that if it were placed in the Solar System, it would extend beyond the orbit of Saturn! It would take a plane 800 years to circle it once.
Mu Cephei
Mu Cephei is very red. It is sometimes referred to as "Herschel's Garnet Star" because it is garnet red. Another alternative name is Erakis, if you don't like the first two names.
KY Cygni
KY Cygni is 200,000 times more luminous than the Sun, and the Sun is pretty luminous, isn't it? The Sun is so luminous you aren't supposed to look at it! However, it's okay to look at KY Cyngi because it is 300 million times farther away.
Larger By Category
Distance from Neptune to Sun
Neptune is the most distant known planet in the solar system. The distance from Neptune to the Sun is greater than the diameter of any known star!
Kuiper Belt
The Kuiper Belt is a region of the Solar System outside the orbit of Neptune where small bodies orbit. Many dwarf planets exist here. It's like a larger asteroid belt.
Distance from Voyager 1 to Earth
Over the last 45 years, Voyager 1 has traveled to a distance of 23 billion kilometers, which is the furthest any man-made object has gone, and every day it gets 1.5 million kilometers further away! You can't see it, even if you stare really, really hard!
