Some of these ended up
on tilted orbits in the distant Kuiper belt, beyond the orbit of Neptune.

The Advanced Laser Interferometer Gravitational - Wave Observatory's detection of spacetime ripples from two merging black holes
on December 26, 2015, indicated that one black hole was spinning like a
tilted top as it
orbited with its companion (SN: 7/9/16, p. 8).
But
on top of that, the
orbits of the six objects are also all
tilted in the same way — pointing about 30 degrees downward in the same direction relative to the plane of the eight known planets.
Although both teams agree that HAT - P - 7b is
orbiting backwards, its
orbit is
tilted with respect to its star's equator, and the two teams disagree
on the degree of
tilt.
The latest observations add yet another head - scratcher: giant gas planets that circle their stars
on wildly
tilted orbits or go around the wrong way altogether.
The Earth's axis wobbles or «precesses»
on a 26,000 - year cycle; it changes its average
tilt on a 41,000 - year cycle; and it shifts its
orbit from being roughly circular to more elliptical
on a 100,000 - year cycle.
Given the revised timeline in this region, Willenbring and colleagues determined that the increased precipitation resulted from changes in the intensity of the sun's radiation
on the Earth, which is based
on the planet's
tilt in
orbit.
There can be irregularities, of course, such as the odd spin axis of Uranus, which for as - yet - unexplained reasons is nearly
tilted on its side, and Pluto's odd
orbit, which occasionally takes it inside the path of Neptune.
Although the initial display shows the system's actual orbital
tilt (at an inclination of 79.2 °) from the visual perspective of an observer
on Earth, the orbital inclination of any planet that may be discovered someday around either star would likely be different from those of the habitable zone
orbits shown here.
It might be lingering bashfully
on the icy outer edges of our solar system, hiding in the dark, but subtly pulling strings behind the scenes: stretching out the
orbits of distant bodies, perhaps even
tilting the entire solar system to one side.
For one, the seasons
on the Earth, and the Earth's climate in general, depend upon its «obliquity,» or the 23.5 - degree
tilt of the Earth's axis relative to its
orbit.
Uranus»
tilt essentially has the planet
orbiting the sun
on its side, the axis of its spin is nearly pointing at the sun.
«The impact of astronomical cycles
on climate can be quite large,» explains Meyers, noting as an example the pacing of the Earth's ice ages, which have been reliably matched to periodic changes in the shape of Earth's
orbit, and the
tilt of our planet
on its axis.
This
orbit is
tilted by 50.68 ° from the perspective of an observer
on Earth (Alan Hale, 1994, see HD 120136; and the Sixth Catalog of Visual
Orbits of Binary Stars).
Although the initial display shows the system's actual orbital
tilt (at an inclination of 136.5 °) from the visual perspective of an observer
on Earth, the orbital inclination of any planet that may be discovered someday around Star A would likely be different from that of the habitable zone
orbit depicted here.
Climate oscillations evident in Fig. 4 of Hansen et al. [52] were instigated by perturbations of Earth's
orbit and spin axis
tilt relative to the orbital plane, which alter the geographical and seasonal distribution of sunlight
on Earth [58].
On December 1, 2009, two astronomers submitted a pre-print suggesting that the planet's extreme axial
tilt (an obliquity of 97 degrees) may have resulted from the presence of a large moon that has since been ejected from
orbit around the ice giant by the pull of another planet during the orbital migration of the giant planets early in the formation of the Solar System.
It has long been known that characteristics of the Earth's
orbit (its eccentricity, the degree to which it is
tilted, and its «wobble») are slightly altered
on timescales of tens to hundreds of thousands of years.
Other planets of the Solar System, especially Jupiter, Mars and Venus, influence the Earth's
tilt and the shape of its
orbit, in a more - or-less cyclic fashion, with significant effects
on the intensity of sunshine falling
on different regions of the Earth during the various seasons.
As the Earth
orbits the sun, the gravitational tug of the other planets slightly alters orbital characteristics (precession,
tilt, ellipticity)
on a timescale of tens of thousands of years.
For the 150 year model what is modelled for short term orbital fluctuations: eg daily rotation, monthly moon gravity effects
on precession etc, yearly elliptical
orbit effects for an assumed fixed elliptical
orbit, yearly
tilt and precession impacts etc?
Precession, which decides whether the Earth is closer to the sun in July or in January, is
on a 23,000 - year cycle; obliquity, which decides how
tilted the axis of the Earth is and therefore how warm the summer is, is
on a 41,000 - year cycle; and eccentricity, which decides how rounded or elongated the Earth's
orbit is and therefore how close to the sun the planet gets, is
on a 100,000 - year cycle.
My planet rotates
on its own axis every 24 hours, has an axial
tilt and rotates around its star in an elliptical
orbit every 365.25 days.
and all working together to form a crude electric motor that deflects charged particles from the sun, which also deflect charged particles from space — while also pulling
on the molten core to divert its heat to different parts of the Earth's surface at different rates... while other rocks
orbiting the sun, also affect the Earth's axial
tilt, particularly Jupiter, thereby changing temperature - extremes.
The timing of the ice ages is believed to be controlled mainly by the earth's
orbit and
tilt, which determines how much sunlight falls
on each hemisphere.
Ice ages and the inter-glacial periods between them are caused principally by predictable variations in the way the Earth
orbits the Sun and
tilts and wobbles
on its axis.
The climatic seasons that we experience
on Earth are caused by a combination of Earth's annual
orbit around the sun and its
tilted axis of rotation.

on Earth are caused by a combination of Earth's annual
orbit around the sun and its
