Study: Jupiter Was Once Twice Its Size With Stronger Magnetism
Scientists have discovered that Jupiter, the largest planet in our solar system, used to be much bigger, around 3.8 million years ago.
Back then, it was twice as wide and could hold about 2000 Earths!
It also had a magnetic field that was 50 times stronger than it is now.
Researchers, including Professor Batygin, studied Jupiter's small moons to learn about these changes.
This helps scientists understand how Jupiter and other planets formed, and how the solar system took shape.
The changes in Jupiter provide a deeper understanding of our solar system's history.
Research indicates Jupiter was twice its present size and had a stronger magnetic field.
The study, published in Nature Astronomy, was led by Professor Konstantin Batygin.
Scientists studied Jupiter's small inner moons, Thebe and Amalthea, to understand the planet's past.
The early Jupiter could have contained a volume equal to approximately 2000 Earths.
These findings provide insights into the early solar system formation.
