The belted giant rotates at a 26.7-degree angle relative to the plane in which it orbits the sun. Astronomers have long suspected that this tilt comes from gravitational interactions with its neighbor ...

Additionally, Triton isn’t even in the same plane — or close to it — that Neptune orbits. It’s tilted at about 23° with respect to the plane that Neptune rotates on its axis, in addition ...

Uranus (left) and Neptune photographed by Voyager 2. NASA/JPL. In our solar system, the two outermost planets of Uranus and Neptune are something of an oddity.

Researchers also found that the relationship between these two moons not only one is tilted, Showalter said, but the number of orbits are peculiar, too. Naiad orbits Neptune 73 times for every 69 ...

Most prominent in the telescope’s view are Neptune’s rings, seen encircling the planet at a slight tilt given its orientation to Earth. The Webb telescope will allow astronomers to measure the ...

A new model describes Neptune's "badly behaved" magnetic field, showing how its tilt and interactions with the solar wind lead to a lopsided magnetosphere. The model could lend insight into ...

Of course, Neptune’s axis isn’t nearly as skewed as Uranus, which is one reason that scientists have struggled to determine what caused Uranus’ strange tilt.

Uranus has the largest tilt in the solar system, at 98 degrees, which means it spins almost perfectly perpendicular to the direction of its orbit. Astronomers have long suspected that a series of ...

In October 2017, NASA released a statement saying that Planet Nine may be 20 times further from the Sun than Neptune is, going so far as to say "it is now harder to imagine our solar system ...

In the early 2000s, scientists put forward the idea that Saturn's tilted axis is a result of the planet being trapped in a resonance, or gravitational association, with Neptune.
