The new discipline of space geodesy appeared in the early 1960s, but the areas of geodetic interest go far beyond the classical study that focused on the size and shape of Earth. Modern geodesy includes scholarly pursuits into the mass distribution within Earth, as manifested by the external ...

the Milky Way a few years ago. However, the newly-detected planet is the smallest rogue world ever found. “Our discovery demonstrates that low-mass free-floating planets can be detected and characterized using ground-based telescopes,” says Prof. Andrzej Udalski, the PI of the OGLE project...
The sun lies at the heart of thesolar system, where it is by far thelargest object. It holds 99.8% of the solar system's mass and is roughly 109 times the diameter of the Earth — about one million Earths could fit inside the sun. ...
