The existence of Neptune was deduced from minute deviations between the predicted and observed orbits of Uranus.
The simulations also showed that rocky planets known as Hot Earths often form inside the orbits of Hot Jupiters.

The data are the orbits of comets that are likely to have been first-time visitors to the inner solar system.
That phase will last about three months, as the Moon completes three rotations beneath the orbits of the two satellites.
FORBES: NASA's GRAIL Mission Will Unlock Secrets Of The Moon's Interior
Their craft actually made 10 orbits of the Moon before returning home.
The mission would further clarify the threat that this particular object poses, and better predict the orbits of other near-Earth asteroids, Beshore said.
After looking at the orbits of almost 300 long-period comets, they have concluded that too many are coming from particular parts of the sky.
But in Dr Ghaffari's trap, the orbits of some of the positrons swelled in size, causing them to lose energy while looping back towards the entrance.
The results could help scientists better understand the swelling and shrinking of our planet's atmosphere, a phenomenon that affects the orbits of satellites and space junk.
To better predict the orbits of hazardous objects, this group is looking at the Yarkovsky effect, a force created when the asteroid absorbs sunlight and re-radiates it as heat.
This corresponds to a place where the gravitational pulls of Mars and Jupiter have conspired to change the orbits of any asteroids much faster than the Yarkovsky effect could manage alone.
Dr Anderson and his team considered some of the proposed modifications to gravity, and found that any adjustment to explain the anomalous acceleration would conflict with the observed orbits of the planets.
But at the same time, what we started to understand about the formation process, we thought there would indeed be a lot of these orbits of giant planets spiraling inward after they're born and things that give you, for instance, hot Jupiters.
It orbits one of a pair of stars 450 light years away, in the constellation Lacerta, circling its host every few days.
And the Moon is close by and always in the sky, unlike the asteroids that flyby the Earth at incredible velocities or inhabit orbits tens of millions of miles away that take years to reach.
FORBES: The Moon is a Natural Platform for Asteroid Mining, Detection and Deflection
Of the 886 valid orbits that they calculated, over 80% of them were asteroid orbits with only a minority being orbits that are associated with comets.
Now imagine that 3D solar system moving in all of its orbits, and realize that each of those planets are also pieces of information searchable by Google.
FORBES: Famo.us Pushes The Physics Of Searchable HTML5 Into A Whole New Universe
And many of these, though they all follow different paths, take the same, surprising, length of time to go round the sun: they complete exactly two orbits for each of Neptune's three.
Harmed by the early death of his father, he orbits the ordinary centres of life and risks flying off into utter loneliness.
They gravitationally interact, and we get these sort of eccentric, elongated orbits and also these sort of closed-in, or what are often called hot Jupiters, which, interestingly, are exacting the sort of thing we see in many cases amongst the exoplanets that have been discovered.
The second, Kepler-35b, orbits a set of twin stars about 5, 400 light years away.
The second, Kepler-35b, orbits a set of twin stars about 5, 400 light-years away.
There is a so-called keyhole a narrow range of orbits that would return Apophis in 2036, should it pass through the keyhole in 2029.
ECONOMIST: The American Association for the Advancement of Science
These modifications will enable the vehicle to better optimize its payload capacity for heavier, more lucrative satellite customers - and also to offer a broader range of orbits to those clients.
As the terrains fly by beneath us, however, we begin to sense that Kaplan has laid out a vast, Ptolemaic astrolabe, with cycles and epicycles and turning inner orbits and mechanics of the sky, elaborating everything and explaining little.
Most are transient visitors to the vicinity of earth their orbits are so long that many of those arriving now (such as Hale-Bopp) must have made any previous visit to the inner solar system before the beginning of recorded history.
Each of the two planets orbits a different star in the Beehive Cluster, which consists of about 1, 000 stars located between 520 and 610 light years away.
Europa, a satellite of Jupiter, and Enceladus, which orbits Saturn, both have large volumes of liquid water buried beneath their icy crusts.
Using this data, the researchers were able to plot a series of possible orbits for the object.
Satellite and space expert Dr Stuart Eves stressed the large uncertainties involved in tracking the "decay" of satellite orbits (their slow fall back into the Earth's atmosphere).
