Explaining how the Solar System got so weird
Almost 5000 exoplanets have been confirmed so far and astronomical observations suggest that the solar system architecture is unusual at the ~1% level or less.
In this talk, I will discuss critical events that shaped the formation of our planetary system. I will use meteorite data, observations of disks around young stars to build a planet formation model that explains why Mars is relatively much smaller than Earth, the origin of Earth’s water, and why the Earth is not a super-Earth — probably the most common type of planet in the Galaxy. Finally, I will also explain how the solar system terrestrial planets luckily survived to Jupiter’s and Saturn’s intemperate past.
