How big is Jupiter?
The NASA spacecraft Juno successfully entered Jupiter’s orbit on July 4th, and has begun its months-long survey of the gas giant. We likely won’t see much of the rich data the probe collects until late August or September, but in the meantime it’s worth pausing to marvel at some amazing facts about our solar system’s largest planet.
Here are seven facts that reveal how massive Jupiter really is.
Jupiter has more than 2.5 times the mass of every other planet in the solar system combined, and 318 times the mass of Earth.
If Jupiter were 80 times bigger, its core would have undergone a cascading nuclear fusion reaction, turning it into a star.
Jupiter has moons big enough to be planets. Ganymede, the largest, is 1.73 times the diameter of Mercury (41% the diameter of Earth) and the ninth-largest known object in the Solar System.
