FarFarOut can be the farthest object in the solar system

Sometimes we thought we had a very good picture of the solar system. There were nine planets, and Pluto was a bit strange, but it was an undeniable planet. Then we discovered several similar "non-neutron objects" (TNO) that resemble Pluto, and scientists have begun to re-evaluate what it means to be a planet. Pluto was degraded and astronomers focused their attention on the outer reach of the solar system in finding distant, glacial planetoids. Last year, astronomers from the Carnegie Institution for Science spotted the farthest planet's dwarfs, called FarOut. FarOut can move – FarFarOut is even more distant.

FarFarOuta's first appearance comes from Scott Sheppard, the Carnegie Institution Astronomer, who last year noticed FarOut. FarOut was already far away at 120 AU (1 AU or astronomical unit is the distance between the Earth and the Sun), which is almost 20 light hours. Initial observations of FarFarOut indicate that the site is about 140 AU. Pluto is only 34 AU away, and the farthest Planet Planet, known as Eris, is at 96 AU.

Sheppard announced the discovery of FarFarOut during a lecture last week when he reviewed his team's data the previous day. The initial frame showing FarFarOut came from the 8-meter Subaru on Mauna Kei in Hawaii, which is hardly strong enough to detect it. Depending on the distance and brightness, Sheppard estimates that the object of the dwarf planet is about 400 kilometers in diameter.

It will take several months or years to determine the precise orbit of FarFarOut. It's so far, one solar year for a dwarf planet is more than 1000 earth years. We do not know what it looks like – this is a technical representation of FarOut at the top, but this is not important, because we also think about it. Several researchers will have to confirm the findings before we can be sure that FarFarOut is really there. Only then can we give her a name – she does not have a smaller marker of the planet.

The Carnegie Institution team really breaks down this discovery of the planet, but this is not the reason why it examines the edge of the solar system. Sheppard and his colleagues search for larger Earth's planets in the external solar system. This theorized "Planet Nine" could explain some of the orbital uncertainties that we see in TNO. It is also possible that there is no Planet Nine, and the integration of the TNO orbit is simply a product of the cumulative weight of many objects, such as FarFarOut. In both cases, the discovery of the dwarf planets is still quite impressive.
