What size is bellatrix?

Bellatrix is a blue giant star. It's not possible to talk about its size in terms of a simple diameter like we would for a planet. Instead, we use stellar classifications and luminosity classes.

Here's what we know about Bellatrix:

* Spectral Type: B2III

* B2 means it's a blue giant star, hot and bright.

* III means it's a giant star, having evolved beyond the main sequence stage of its life.

* Luminosity: Around 9,200 times the luminosity of our Sun.

* Radius: Approximately 7 times the radius of our Sun.

To give you a better idea:

* If our Sun was a basketball, Bellatrix would be about the size of a house.

* It's so large that if it were to replace our Sun, it would engulf Mercury, Venus, Earth, and Mars.

Important note: These are estimates, and the exact size of Bellatrix might vary slightly based on different studies and observational data.
