NASA Studied Mercury To Calculate Sun’s Loss Of Mass, Gravitational Pull

The sun is about half-way through its lifespan of 10 billion years in its current state, and in all the time it has been around, it has lost some mass. As our familiar star ages and continues losing mass, its gravitational pull on the solar system weakens as well. A team of researchers from NASA and Massachusetts Institute of Technology (MIT) studied changes in the orbit of Mercury to determine the rate at which solar mass is being lost, which has implications for our knowledge of some other...
