After 350 years, astronomers still can’t explain the solar system’s strangest moon​

Saturn's Iapetus, discovered way back in 1671, has three bizarre features that science still can't fully explain.

Based on the atoms that they're made out of, the innermost planet should always be the densest. Here's why Earth beats Mercury, hands down.

I suspect the transformative event was nearly twice as long ago/back, but here is a candidate for consideration. Events and consequences are similar to what may have occurred more closer to 4+Billion years ago.

From the above link;
...
But we can’t be sure, and astronomers are excited. Betelgeuse is about 15 to 20 times more massive than the Sun, and stars of this mass are expected to end their lives in a powerful explosion known as a supernova. Betelgeuse’s red color shows it is a red supergiant, meaning it’s already approaching the end of its life.

But that end may still be a million years away. Stars like Betelgeuse can live in excess of 10 million years — a very brief period to astronomers but a very long time to anyone else.

Despite this, new models have been run, with some suggesting that a supernova could happen within a few thousand years, while others put this event at 1.5 million years into the future.

There are many mysteries around Betelgeuse. We don’t know its precise mass — and even its distance is disputed. It is argued that the star merged with a smaller companion recently: this would explain why it rotates faster than expected — large stars usually do.

Scientists discover secret planet hiding in our solar system​

EXCERPT:
...
Turns out that might be the case. Astronomers have calculated there is a 7 per cent chance that Earth has another neighbour hiding in the Oort cloud, a spherical region of ice chunks and rocks that is tens of thousands of times farther from the sun than we are.

“It’s completely plausible for our solar system to have captured such an Oort cloud planet,” said Nathan Kaib, a co-author on the work and an astronomer at the Planetary Science Institute.
...
“The survivor planets have eccentric orbits, which are like the scars from their violent pasts,” said lead author Sean Raymond, researcher at the University of Bordeaux’s Astrophysics Laboratory.

That means that the Oort cloud planet could have a significantly elongated orbit, unlike the near-perfect circle Earth tracks around the sun.

Trouble is, when things are that far away, they’re pretty difficult to spot. “It would be extremely hard to detect,” added Raymond.

“If a Neptune-sized planet existed in our own Oort cloud, there’s a good chance that we wouldn’t have found it yet,” said Malena Rice, an astronomer at MIT not involved in this work.
