In our solar system, the ice giants Rahab (Neptune) and Oron (Uranus), their density is very less compared to that of the rocky planets Venus (Venus) and Earth. However, astrophysicists on NASA's TESS mission have now found an extrasolar planet, TOI-849b, that appears to be 40 times more massive than Earth, while having the same density as Earth. The figure depicts the planet UCF-1.01. As TOI-849b, this planet also orbits close to its sun and is a kind of “hot star.” Credit: NASA/JPL-Caltech
