Here's why:
* Canis Majoris is a star. Stars are immense balls of hot gas, much larger than any planet or even the entire solar system.
* Canis Majoris is a supergiant. This means it's incredibly large, even compared to other stars.
* Size Comparison: If you were to place Canis Majoris at the center of our solar system, its outer edge would extend far beyond the orbit of Pluto.
To give you a better idea of its size:
* The Sun's diameter is about 1.4 million kilometers.
* Canis Majoris's diameter is estimated to be around 1,300 times that of the Sun, meaning it's around 1.8 billion kilometers across.
So, Canis Majoris is truly enormous, dwarfing the entire solar system in size.
