We haven't found an exact solar system analog, which would have a circular orbit and a mass closer to that of Jupiter. But this shows we are getting close.

There is not much margin to get (the satellites) in the exact orbit we want it to be. It's an instantaneous launch window -- either you go or don't go.

In the coldest part of the solar system, we have found samples that formed at extremely high temperatures?so the hottest samples [are in] the coldest place.

We're going to understand that there is life on other bodies in the solar system.

This success permits us to hope that after thirty or forty years of observation on the new Planet [Neptune], we may employ it, in its turn, for the discovery of the one following it in its order of distances from the Sun. Thus, at least, we should unhappily soon fall among bodies invisible by reason of their immense distance, but whose orbits might yet be traced in a succession of ages, with the greatest exactness, by the theory of Secular Inequalities.

[Following the success of the confirmation of the existence of the planet Neptune, he considered the possibility of the discovery of a yet further planet.]

It's time for the human race to enter the solar system.
