Our solar system is weird

Saturn is essential for the Grand Tack theory. If there was no Saturn, Jupiter would have stayed close in near the Sun, and some of the super-Earths would have survived, making our solar system just like all those exoplanetary systems out there.

That’s a pretty sweet explanation of how our solar system came to be so unusual. But is the Grand Tack theory right?

Only time – and observational-data-confirming-or-rejecting-testable-predictions – will tell.
