Aquarius Beta (Sadalsuud) is a giant star, meaning it is much larger and cooler than our sun. However, there isn't a single temperature that defines the entire star.

Here's a breakdown of the relevant information:

* Surface Temperature: The surface temperature of Sadalsuud is about 7,200 Kelvin (6,927 degrees Celsius or 12,500 degrees Fahrenheit). This is cooler than our sun, which has a surface temperature of 5,500 Kelvin.

* Core Temperature: The core of a star is incredibly hot. Sadalsuud's core temperature is estimated to be millions of degrees Kelvin. However, this temperature is not directly measurable.

So, while you can specify a surface temperature for Sadalsuud, it's important to remember that the temperature of the star varies drastically depending on the location within the star.
