Hajdukovic's quantum gravity might create a similar discrepancy with more
distant orbiting bodies, he says — which is where Eris and its moon Dysnomia come in.
Not exact matches
This clustering of orbital parameters of the most
distant KBOs suggested a large, planetary size
body shepherding their
orbits.
Some candidates can be checked further using another technique that looks for «wobbles» in the star caused by the gravitational tug of an
orbiting body, but Kepler 452 b is too
distant and small for that.
Like an unseen spider visibly tugging on a web of gravitational strings, a hidden celestial
body is luring
distant space rocks into clusters of
orbits too conspicuous to ignore.
As improved telescope technology finds smaller and more
distant asteroids, astronomers have identified clusters of similar - looking
bodies clumped in analogous
orbits.
But only the lucky binaries seem to have planets that
orbit them; some stellar binaries that lack
orbiting bodies have a different third party — a
distant star that's so massive, its gravitational fluxes actually change the
orbit of the stellar binary, causing the two stars to shrink together in a process called orbital decay.
Since January, scientists have been chasing Planet Nine: a
distant hypothetical world that could have 10 times the mass of Earth and explain the peculiarly clustered
orbits of six icy
bodies beyond Neptune.
This mixture resembles the composition of ancient
bodies from cold
distant orbits — such as Comet Borrelly, which another NASA probe flew past in 2001 (ScienceNOW, 18 December 2001).
Astronomers also use NIRC2 to map surface features of solar system
bodies, detect planets
orbiting other stars, and study detailed morphology of
distant galaxies.
The goal, says former survey leader Robert Millis, was to discover enough
distant bodies to begin to understand the scale of the belt, the three - dimensional distribution of these objects in space, and their
orbits.
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.
Other solar system
bodies that are possibly dwarf planets include Sedna and Quaoar, small worlds far beyond Pluto's
orbit, and 2012 VP113, an object that is thought to have one of the most
distant orbits found beyond the known edge of our solar system.
Since these
distant bodies move around the sky slowly, it will take about a year of follow up observations to understand their
orbits — and their origins.
Each proposed scenario creates a population of icy
bodies beyond the Kuiper belt and leaves a distinctive imprint on the
orbits of these
distant objects that would be still be observable today.
