Possible Discovery of Ocean World Orbiting Sun-Like Star

Astronomers have discovered an exoplanet called TOI-733b, which is just under twice the radius of Earth and is orbiting a star a little smaller than the Sun with a period of 4.9 days. The exoplanet may have lost its atmosphere or be an ocean-covered water world. The discovery could help scientists figure out a curious gap in the exoplanet record: why there are so few worlds between 1.5 and 2 Earth radii.
