Episode notes
The frequency of the sound waves of all these heavenly bodies is really determined by the density of the object. And so stars are gases, and their density is very different from the density here on Earth. So by measuring the frequencies of the quakes, we know quite directly how big the object is and what its density is. If you know these two, then you know the mass. We need to send some space mission there to come closer and to be able to see this.
