What’s Inside Jupiter? Close Encounters With The Giant | Video
On March 8th, 2016, Jupiter and Earth are closest, at 413 million miles, which happens every 13 months. In July, the Juno probe will enter Jovian orbit, skimming just 3100 miles from the cloud tops. Repeated passes should give researchers a good idea of the planet’s composition, which likely includes ha vast reserve of hydrogen compressed to the metallic state surrounding a rocket ice core.
