The 9.8
years orbit results quite eccentric (e = 0.57), as typical for massive giant planets.

Another paper published earlier this
year presented the
results of numerical simulations providing a range of possibilities for the mass and
orbit for such a hypothetical planet, that could account for the observed clustering of eKBO
orbits.
«So when people tell me, «You haven't got any
results,» when we've only been in
orbit for a
year, I say, «Stop!
The Van Allen Probes are a great mission, and part of that credit goes to the late Gene Heyler [who passed away in March 2013], who designed the
orbits so that the satellites lap each other several times per
year, which has been a key to the science
results the mission can achieve.
Their
results indicate a possible planet approximately the mass of Neptune — the smallest yet seen around a sunlike star —
orbiting every 280
years.
It will be a few
years before we see the
results of this mission as, even through the Sun is quite close in astronomical terms, it is still a huge distance from the Earth and the mechanics of getting the probe into the right
orbit require multiple
orbits and positioning.
Let's say if we could launch, we could get in the
orbit of Jupiter and Europa by 2022, you'd get
results back by 2025 and then things don't happen as fast as you think they would so add ten
years.
The Sagittarius Dwarf is believed to already have
orbited the Milky Way about 10 times in the last billion
years or so, and it still appears to have coherence as an elongated ellipse despite being torn apart by enormous tidal forces as a
result of the interaction.
Warming in the early to mid-Holocene (the post-glacial period that covers the last 12,500
years)
resulted from changes in the earth's
orbit (as described by Milankovitch).
As a
result of Earth's elliptical
orbit, the time between the autumnal equinox and the following vernal equinox (about September 22 to about March 21) is almost one week shorter than the remainder of the
year in the Northern Hemisphere.
This
results in a very complex and constantly changing dance of the sun around the solar barycenter... but not regular 60 and 20
year orbit cycles.
The
results confirmed elaborate calculations of
orbits that indicated that the next ice age would not come naturally within the next ten thousand
years or so, maybe in 20 - 30,000
years.
