When the orbits become more oval in shape, the bodies will come in increasingly close proximity when passing at the shortest point.

Now, new results from NASA's Dawn spacecraft, which has been orbiting Ceres since March, hint that the body may have much more in common with its diminutive dwarf - planet cousin Pluto than once thought.

Dawn began orbiting Ceres in 2015, following its exploration of Vesta, the asteroid belt's second largest body.

Its moon Charon, discovered in 1978, is almost as big as Pluto itself and so massive that the two bodies orbit around each other.

Between 1892, when Poincaré published his treatise on the problem, and the mid-1960s, a series of mathematicians followed Poincaré's suggestion of painstakingly looking for weirdly shaped periodic orbits — the mathematical loops in the fabric of a three - body gravitational field.

As improved telescope technology finds smaller and more distant asteroids, astronomers have identified clusters of similar - looking bodies clumped in analogous orbits.

Astronomers once pictured the Kuiper belt as a giant ring - shaped collection of bodies along a disklike plane, called the ecliptic, in which Earth and all the other major planets orbit.

That causes our planetary companion to pop out from the synestia, leaving it in orbit around the body that will keep cooling until it resembles Earth.

Then calculate where those n bodies will be going, at what speed, and in what trajectories or orbits, from now until the end of time.

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.

You have solids in orbit in a disk, and the solids run into each other and stick and build progressively larger and larger bodies.

In 2006, IAU members officially adopted the term «dwarf planet» for certain minor orbiting bodies.

Although the consequences are roughly comparable in either case, an important difference is that objects in the solar system that circle far away from the sun on long - period orbits before returning, such as comets, would hit the earth at much greater velocities than close - orbiting (short - period) bodies, such as asteroids.

They looked for objects moving in orbits similar to those of Pluto and the large bodies in the Kuiper Belt, whose motion is influenced in a characteristic fashion by the gravitational pull of Neptune.

Several bodies had recently been discovered orbiting in the outer solar system with a size similar to Pluto's, culminating in Eris, which appeared to be bigger.

In 1915, Einstein explained that gravity arises because massive bodies warp space and time, or spacetime, causing free - falling objects to follow curved paths such as the arc of a thrown ball or the elliptical orbit of a planet around its sun.

Amalthea probably arose in Jupiter's youth as a solid body near its current orbit, says planetary formation theorist Robin Canup of the Southwest Research Institute in Boulder, Colorado.

The moon is a bonanza for scientists, Kring says, because it offers crucial insights for understanding the origins and evolution of Earth and other planets: how they formed from the accretion and differentiation of smaller bodies; how they were bombarded by impacts early in their histories; and even how some of them migrated in their orbits around the sun.

New Horizons also could potentially take a close - up look at a smaller, more ancient object much farther out in the Kuiper Belt: the disk - shaped region beyond the orbit of Neptune believed to contain comets, asteroids and other small, icy bodies.

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).

Even though many of the planets orbit their stars very closely and have high temperatures, which in turn causes their hydrogen - rich atmospheres to expand and a fraction of the gases to escape the planet over time, it's unlikely that the planets will lose enough of their atmosphere to become rocky bodies like Earth, the researchers report online today in the Monthly Notices of the Royal Astronomical Society.
