Study: Jupiter Was Twice Its Size, Shaped Solar System
Imagine Jupiter, the biggest planet, was once even bigger!
Scientists discovered Jupiter used to be twice its size and had a super strong magnetic field, 50 times stronger than it is now.
They figured this out by studying the orbits of Jupiter's tiny moons, like Amalthea and Thebe.
These moons' slight tilts gave clues about the planet's past.
This giant Jupiter helped shape all the other planets in our solar system.
Even after billions of years, scientists are still learning about how our solar system was created by looking at the past of this planet.
Jupiter was twice as big in the past.
Jupiter's magnetic field was about 50 times stronger.
The study analyzed Jupiter's moons Amalthea and Thebe.
Jupiter played a key role in shaping the solar system.
The research helps understand how the solar system formed.
