Astronomers spot distant object that supports Planet Nine theory

"Goblin" dwarf planet found lurking at the extreme fringes of the solar system

These data also helped to suggest the gravitational influence of an unknown planet, several times larger than the Earth. So it may come as a surprise to some that there is a potential new contender for the ninth planet, based on the discovery of another newly discovered celestial body with an amusing nickname. 2015 TG387 can be seen moving between the images near the center, while the more distant background stars and galaxies remain stationary. "They can be used as probes to understand what is happening at the edge of our Solar System".

Step by step, astronomers are growing tantalizingly close to finding the solar system's long-rumored "Planet Nine" lurking somewhere farther out than Pluto: they've got everything from odd asteroid orbits to medieval manuscripts on their side, and now a tiny planet nicknamed "The Goblin" brings even more credence to the theory that there's something out there messing with the orbits of tiny worlds out in the Kuiper Belt-and beyond.

PALCA: Sheppard is an astronomer with the Carnegie Institution for Science.

The researchers, including Sheppard, Northern Arizona University's Chad Trujilllo and the University of Hawaii's David Tholen, have also submitted a paper to the Astronomical Journal detailing their findings. The discovery was announced Monday following years of observations.

2012 VP113 has the most distant orbit at perihelion, at just over 80 AUs. This was referred to the lineup of the solar systems in which it is four biggest planets that include Saturn, Jupiter, Neptune as well as Uranus.

Sheppard said the faraway objects are "like breadcrumbs leading us to Planet X".

According to its discoverers, 2015 TG387 has an elongated orbit that never comes close to the Sun.

"We think there could be thousands of small bodies like 2015 TG387 out on the solar system's fringes, but their distance makes finding them very hard", said David Tholen, an astronomer at the University of Hawaii. "Currently we would only detect 2015 TG387 when it is near its closest approach to the sun".

It follows an elongated 40,000 years orbit that never brings it close to the Sun.

It took several years of measurement, but now Sheppard says they have a pretty good idea of The Goblin's orbit, and it's definitely interesting.

As per the astronomers, they have observed the dwarf planet on 13th October 2015 who is from Subaru telescope at Hawaii's Mauna Kea Observatories.

2015 TG387 is likely on the small end of being a dwarf planet since it has a diameter near 300 kilometers.

The location of the Goblin's perihelion is similar to the perihelion's of Sedna, 2012 VP113, and other extremely distant Trans-Neptunal Objects. "If the trends are true, then we don't know of another explanation for why they would be grouped in an orbit like this", Sheppard said.

Nathan Kaib of Trujillo University in Peru, and the University of Oklahoma, ran computer simulations to determine the cause of the TNOs. While the huge planets in your system manifest an intense gravitational pool, Goblin seems unfazed by them, which leads scientists to believe that a greater force may be affecting it.

Meanwhile, Sheppard and the rest of his research team will begin a new search starting next month to locate other objects in the fringes of the solar system, including Planet Nine.

The researchers believe that a hypothetical object dubbed Planet X might exist on the edges of the Solar System, helping to shepherd objects lying beyond Neptune.
