"Tilted orbits" refers to the path or trajectory of an object in space, like a planet or moon, that is not perfectly aligned or flat. Instead, its path is slightly tilted or inclined compared to another object or plane. Full definition
Previous research suggested that Planet Nine would possess a highly tilted orbit compared with the relatively thin, flat zone in which the eight official planets circle the sun. (space.com)
Then we started finding some that were misaligned — planets with tilted orbits or planets going around their star in the opposite direction from its spin, in what we call a retrograde orbit. (discovermagazine.com)
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. (discovermagazine.com)
