An extremely low-density planet has been discovered orbiting a G-dwarf star with super-solar metallicity, suggesting that metal-poor environments are not necessary to create low-density exoplanets.

Does the Sun’s diameter vary as a function of time, and is it related to solar activity? Measurements taken during the rising phase of the current solar cycle suggest the answer is “no”.
