It seems like you're asking about the brightness of stars and how it relates to magnitude. Here's a breakdown of what's important:

* Magnitude: A measure of a star's apparent brightness as seen from Earth. The lower the magnitude number, the brighter the star.

* Magnitude Scale: It's a logarithmic scale, meaning each step in magnitude represents a significant difference in brightness.

The problem with your question: You've provided a magnitude of "1" but then said "of 2." This is confusing. Let me explain why:

* You can't have a magnitude "of" something: A magnitude is a single number describing a star's brightness. You don't say a star has a magnitude "of" another number.

Here's what you might have meant to ask:

* "How much brighter is a magnitude 1 star compared to a magnitude 2 star?"

Answering that question:

A magnitude 1 star is 2.512 times brighter than a magnitude 2 star. This is because the magnitude scale is logarithmic, with each step representing a factor of about 2.512 in brightness.

Important Note: The magnitude system is a little tricky because it's historically based on how bright stars *appear* to us. This means it's affected by distance. A star that's intrinsically dim but very close to us can have a low magnitude, while a star that's incredibly luminous but far away could have a high magnitude.
