朱诺发现木星比想象的要小一点, 并且比想象中模糊得多, 改变了对木星形状和内部的理解。 Juno finds Jupiter is slightly smaller and more oblate than thought, reshaping understanding of its shape and interior.

美国航天局的朱诺号航天器发现,木星比以前想象的要小一点,比以前略微模糊一些,新的赤道直径为88,841英里(142,976公里),极直径为83,067英里(133,684公里),比以前估计的要小5至15英里。 NASA's Juno spacecraft has found Jupiter is slightly smaller and more oblate than previously thought, with a new equatorial diameter of 88,841 miles (142,976 km) and a polar diameter of 83,067 miles (133,684 km), about 5 to 15 miles smaller than earlier estimates. 根据2016-2024年稀有地球观察对齐期间收集的无线电信号数据,改进后的测量结果揭示出木星大气层对木星形状的影响超过人们所相信的程度。 The improved measurements, based on radio signal data collected during a rare Earth-view alignment in 2016–2024, reveal Jupiter’s atmosphere affects its shape more than believed. 研究结果发表在《自然天文学》上,完善了木星内部、大气动态和太阳系形成作用模型。 The findings, published in Nature Astronomy, refine models of Jupiter’s interior, atmospheric dynamics, and role in solar system formation.
