The size of the Sun may be smaller than previously thought

It is noted that the radius of our star today is measured using gravitational forces, which, according to some scientists are not reliable for this purpose, because they are reflected without reaching the edge of the Sun’s photosphere, thus creating a kind of “phantom surface”.

“Pressure waves,” on the other hand, are less affected by the magnetic field and turbulence in the upper surface layers of the star’s convection zone, allowing them to penetrate deeper. Calculations based on these data indicate that the Sun’s radius, albeit slightly, is still smaller than thought.
