How would Solar System formation look to an outside observer

5 How would Solar System formation look to an outside observer 

By approximately 1—3 Myr, the accretion rate and disk mass would have decayed substantially, leading to a less turbulent, cooler, and lower-mass disk, possibly with 

We know with confidence that the Solar System is much richer in less-refactory material than it is in refactory materials. In the subsequent stage a fraction of the refractory dust was processed into chondrules. The number and relative mass of chondrules is far greater than CAIs, although the size of the regions where they are processed is about equal to that of CAIs. Therefore we would see an increase in the local luminosity at the sites of the heating events, with an appreciable fraction of the dust being sequestered into chondrules. If shock waves driven by a massive planet were present, the planet would deform the disk structure and possibly open an observable gap.
