1.9885 × 10^30 kilograms
This value is based on various observations and calculations, including:
* Orbital periods of planets: By observing the orbital periods of planets around the Sun, we can calculate its gravitational pull and thus its mass.
* Solar oscillations: The Sun vibrates like a giant bell, and these vibrations can be analyzed to determine its internal structure and mass.
* Stellar models: Sophisticated computer models of the Sun can be used to estimate its mass based on its luminosity, temperature, and composition.
It's important to note that this figure is still an approximation, and there is a small margin of error. The uncertainty in the Sun's mass is estimated to be around ± 0.0001 × 10^30 kilograms.
While this might seem like a small difference, it's a significant amount when dealing with such a massive object.
