Juno Redefines Jupiter's Size, Shape

NASA's Juno mission has unveiled a surprising new portrait of Jupiter, revealing the gas giant is 8 kilometers narrower at its equator and 24 kilometers flatter at its poles than previously believed. This precise re-measurement, achieved through 13 radio occultation flybys, is crucial for accurately modeling distant exoplanets and updates decades-old data.

Juno Redefines Jupiter's Size, Shape
  • NASA's Juno mission reveals Jupiter is 8 kilometers narrower at the equator and 24 kilometers flatter at the poles than previously estimated.
  • Scientists refined these measurements using radio occultation data from 13 flybys, a technique precisely gauging Jupiter's internal structure.
  • This updated understanding, published in Nature Astronomy, is vital for accurately modeling giant exoplanets beyond our solar system.
  • Previous estimates relied on less precise data from the Pioneer and Voyager missions nearly 50 years ago, according to Xinhua.
