木星属于我们称之为气态巨行星的那一类，不是因为它们是由气体组成的，而是因为它们主要是由氢氦气体构成的，氢氦气体在重力压缩下会变成金属流体。朱诺号自2016年以来一直在木星轨道上运行，它改变了我们的观点：重力数据得到了很大的改善，对高次偶数谐波的最简单解释表明，这颗行星的重元素中心浓度可能被稀释了。木星的强风可以延伸到大约3000公里的深度，这在重力场奇怪的纬向谐波中很明显。木星独特的磁场显示出一些有限的局部结构，最引人注目的是大蓝斑（赤道附近一个向下流动的区域），以及一些长期变化的证据，可能是由风引起的。然而，朱诺正在进行中；它没有回答所有的问题，还提出了新的问题。▪朱诺号的任务揭示了木星的内部。▪地核存在，但被氢稀释。▪该任务揭示了风的深度和磁场。
Jupiter is in the class of planets that we call gas giants, not because they consist of gas but because they were primarily made from hydrogen-helium gas, which upon gravitational compression becomes a metallic fluid. Juno, in orbit about Jupiter since 2016, has changed our view: The gravity data are much improved, and the simplest interpretation of the higher order even harmonics implies that the planet may have a diluted central concentration of heavy elements. Jupiter has strong winds extending to perhaps ∼3,000-km depth that are evident in the odd zonal harmonics of the gravity field. Jupiter's distinctive magnetic field displays some limited local structure, most notably the Great Blue Spot (a region of downward flux near the equator), and some evidence for secular variation, possibly arising from the winds. However, Juno is ongoing; it has not answered all questions and has posed new ones. ▪ Juno's mission reveals Jupiter's interior. ▪ A core exists but is diluted by hydrogen. ▪ The mission revealed wind depth and magnetic field.
