Jakarta, CNBC Indonesia – Our solar system was formed billions of years ago. But the planets in it were not born simultaneously.
IFL Science noted the possibility of the first planet to form and become the oldest is Jupiter. According to the page, it was formed in the first 3 million years of the Solar System, quoted on Wednesday (12/4/2023).
Callisto’s moon is also called the oldest in this solar system. After Jupiter, other large planets began to appear in the solar system. Starting from Saturn and followed by two other planets Neptune and Uranus.
After that, the inner solar system began to form. There are four new planets and one dwarf planet that appears in it.
According to IFL Science, the rocky planet took longer to form, which is about 100 million years. The reason is because it relies on collisions between rocky differences.
The planet Mars is probably the fastest gaining its current size. Much faster than Earth or the planet Venus.
Then what planet is the youngest or last present in the solar system? For this problem there could be a long debate, and the two candidates are Earth and Uranus.
Earth is the youngest planet candidate because of the possibility of a collision with a planetoid as big as Mars, Theia. This event occurred 4.5 billion years ago. The collision of the two was the beginning of the formation of the Moon.
Earth needs more time to become like this, including the formation of oceans and plate tectonics. For the latter, it is likely that it occurred 3.5 billion years ago.
On the other side of the solar system, Uranus also collided with a planet as big as Earth 3-4 billion years ago. This makes it spin sideways and generates the strangest magnetic fields.
