Hayabusa2 had an exciting voyage across our solar system, getting into dust ups and even coming back home again with data to share. We've been tracking the long journey of Hayabusa2 over the 10 years of this podcast, and we're now getting interesting data from the returned samples. The Hayabusa2 probe shot at the asteroid Ryugu and brought back proof for JAXA to study and it tells tales of a very early time in our solar system. Ryugu is much much older than we thought, born only 1.8 million years after the formation of our solar system. How does a planetary system form and why are some planets in a flat line and others really odd. Our Nepture is an anomaly not just in our solar system but also compared to others. What happened to all the other 'Hot Neptune' exoplanets? Did they get burnt off or flung away?
