Jupiter was once twice as large as it is now and had a 50 times stronger magnetic field

Jupiter, already the largest planet in our solar system, was once much larger, scientists have discovered. A new study published in Nature Astronomy reveals that Jupiter was twice its current size and had a magnetic field 50 times stronger during its early formation.

Researchers Konstantin Batygin and Fred Adams studied Jupiter's small moons Amalthea and Thebe to reconstruct the planet's original state. Their findings provide insights into the early stages of our solar system's formation.
