If we were to imagine the Sun as a hollow structure, it would have the capacity to hold a staggering number of approximately 64.3 million moons! This mind-boggling estimate highlights the immense size of our Sun. However, it’s worth noting that the Sun is not the most massive star in the universe. Scientists believe that around 10 percent of known stars possess more mass than our Sun.

How many Earths can fit in the Sun exactly?
When considering the size and distance, it becomes apparent that the Sun is a medium-sized star with a radius of approximately 435,000 miles (700,000 kilometers). Although there are stars much larger than the Sun, it still exhibits a significantly greater mass than our home planet. In fact, it would require over 330,000 Earths to match the mass of the Sun. Furthermore, the volume of the Sun could accommodate a staggering 1.3 million Earths.
Here are a few interesting facts about the Sun’s positioning:
- The Sun is situated around 93 million miles (150 million kilometers) away from Earth.
- Its closest stellar neighbor is the Alpha Centauri triple star system. Proxima Centauri, a red dwarf star, lies 4.24 light-years away, while Alpha Centauri A and B, two sun-like stars orbiting each other, are 4.37 light-years away.
- A light-year is the distance that light travels in one year, equivalent to approximately 6 trillion miles (9.5 trillion kilometers).
To further enhance our understanding, let’s delve into the topic of the Sun’s orbit and rotation.
Orbit and Rotation
Now, let’s explore the intriguing question of how many moons can fit inside the Earth.
Considering the Earth’s significantly larger size compared to the moon, it would take around 50 moons to fit within the Earth. The Earth boasts a volume of approximately 260 billion cubic miles, while the moon’s volume measures around 5.25 billion cubic miles.
Moving on, let’s discover the grandeur of the universe’s largest known star.
What is the biggest star ever?
The universe’s largest known star is UY Scuti, a red hypergiant. This massive star possesses a radius estimated at 1.188 billion kilometers. To put this into perspective, if UY Scuti were positioned at the center of our solar system, its outer shell, known as the photosphere, would extend beyond the orbit of Jupiter.
Hypergiants like UY Scuti possess extraordinary mass and luminosity. However, they are relatively challenging to locate due to their short life spans. Unlike stars that can endure for billions of years, hypergiants exist for only a few million years. UY Scuti was initially discovered in 1860 by German astronomers and was designated “BD-12 5055” at the time. This colossal star resides near the center of the Milky Way and is located approximately 9,500 light-years away from Earth.
As we conclude this exploration, it’s important to stay curious and continue to seek answers to life’s everyday questions.
