Jupiter Is The Oldest Planet In Our Solar System, Study Confirms

Study confirms Jupiter as the oldest planet in our Solar System. Looking at tungsten and molybdenum isotopes on iron meteorites, researchers found that meteorites are made up from two genetically distinct nebular reservoirs that coexisted but remained separated between 1 million and 3-4 million years after the explosion of a nearby star called a supernova 4600 million years ago that led to the formation of Solar System.
