2018 VG18

2018 VG18 is a distant trans-Neptunian object that was discovered well beyond 100 AU (15 billion km) from the Sun. It was first observed on 10 November 2018 by astronomers Scott Sheppard, David Tholen, and Chad Trujillo during a search for distant trans-Neptunian objects whose orbits might be gravitationally influenced by the hypothetical Planet Nine. They announced their discovery on 17 December 2018 and nicknamed the object "Farout" to emphasize its distance from the Sun.

Astronomers just discovered the farthest object in the solar system - “2018 VG18″

On December 17, 2018, astronomers announced the discovery of the most distant known object in the Solar System: a trans-Neptunian object designated 2018 VG18. Nicknamed “Farout” by its discoverers, the object is currently positioned at a distance of roughly 120 AU from the Sun, twice the average distance of Eris, the previous record-holder for distance. 2018 VG18 appears to be roughly 500 km in diameter, potentially qualifying it as a dwarf planet. 

At this distance, 2018 VG18 moves very slowly across the sky, so astronomers will only be able to measure an accurate orbit after several years of observations. 

The Magellan observations confirmed that 2018 VG18 is around 120 AU, making it the first Solar System object observed beyond 100 AU.  Its brightness suggests that it is about 500 km in diameter, likely making it spherical in shape and a dwarf planet. It has a pinkish hue, a color generally associated with ice-rich objects.

A group of astronomers have identified the most distant object ever observed within our solar system.

Provisionally named 2018 VG18, but nicknamed Farout by its discoverers, the body is 120 astronomical units (AU) from the sun. One AU is equal to the average distance from the Earth to the sun, or just under 150m kilometres. The previous furthest known object was Eris, 96 AU from the sun.

The discovery was made by Scott S Sheppard of the Carnegie Institution for Science in Washington DC, David Tholen of the University of Hawaii and Chad Trujillo of Northern Arizona University. It was announced on Monday by the Minor Planet Center.  ...

'Farfarout'! Solar system's most distant planetoid confirmed A team, including an astronomer from the University of Hawai?i Institute for Astronomy (IfA), have confirmed a planetoid that is almost four times farther from the Sun than Pluto, making it the most distant object ever observed in our solar system. The planetoid, nicknamed "Farfarout," was first detected in 2018, and the team has now collected enough observations to pin down the orbit. The Minor Planet Center has now given it the official designation of 2018 AG37. Farfarout's name distinguished it from the previous record holder "Farout," found by the same team of astronomers in 2018. The team includes UH Mānoa's David Tholen, Scott S. Sheppard of the Carnegie Institution for Science, and Chad Trujillo of Northern Arizona University, who have an ongoing survey to map the outer solar system beyond Pluto. Journey around the Sun Farfarout's current distance from the Sun is 132 astronomical units (au); 1 au is the distance between the Earth and Sun. For comparison, Pluto is only 34 au from the Sun. The newly discovered object has a very elongated orbit that takes it out to 175 au at its most distant, and inside the orbit of Neptune, to around 27 au, when it is closest to the Sun. Farfarout's journey around the Sun takes about a thousand years, crossing the giant planet Neptune's orbit every time. This means Farfarout has probably experienced strong gravitational interactions with Neptune over the age of the solar system, and is the reason why it has such a large and elongated orbit. "A single orbit of Farfarout around the Sun takes a millennium," said Tholen. "Because of this long orbital period, it moves very slowly across the sky, requiring several years of observations to precisely determine its trajectory." Discovered on Maunakea Farfarout will be given an official name after its orbit is better determined over the next few years. It was discovered at the Subaru 8-meter telescope located atop Maunakea in Hawai?i, and recovered using the Gemini North and Magellan telescopes in the past few years to determine its orbit based on its slow motion across the sky. Farfarout is very faint, and based on its brightness and distance from the Sun, the team estimates its size to be about 400 km across, putting it on the low end of being a dwarf planet, assuming it is an ice-rich object. "The discovery of Farfarout shows our increasing ability to map the outer solar system and observe farther and farther towards the fringes of our solar system," said Sheppard. "Only with the advancements in the last few years of large digital cameras on very large telescopes has it been possible to efficiently discover very distant objects like Farfarout. Even though some of these distant objects are quite large, being dwarf planet in size, they are very faint because of their extreme distances from the Sun. Farfarout is just the tip of the iceberg of solar system objects in the very distant solar system." Interacting with Neptune Because Neptune strongly interacts with Farfarout, its orbit and movement cannot be used to determine if there is another unknown massive planet in the very distant solar system, since these interactions dominate Farfarout's orbital dynamics. Only those objects whose orbits stay in the very distant solar system, well beyond Neptune's gravitational influence, can be used to probe for signs of an unknown massive planet. These include Sedna and 2012 VP113, which, although they are currently closer to the Sun than Farfarout (at around 80 au), they never approach Neptune and thus would be most influenced by the possible Planet X instead. "Farfarout's orbital dynamics can help us understand how Neptune formed and evolved, as Farfarout was likely thrown into the outer solar system by getting too close to Neptune in the distant past," said Trujillo. "Farfarout will likely interact with Neptune again since their orbits continue to intersect."

Say hello to 2018 VG18, the most distant solar system object ever spotted. Nicknamed “Farout,” it’s about 120 to 130 astronomical units (AU) from the sun (where one AU is equal to the 93 million miles between the star and our home planet, because humans are self-referential like that). For reference, Pluto—commonly introduced to students as one of the most distant planetary objects in the solar system—is a measly 34 AU away, hardly scratching our cosmic neighborhood’s outer fringes. 2018 VG18 also beats out Eris, the dwarf planet infamous for inspiring Pluto’s status demotion, which previously held the record at 96 AU from the sun. The Voyager 2 spacecraft, which just exited the heliosphere (though not the solar system itself) is about the same distance as 2018 VG18. Our sun’s most distant orbiting comets, which mark the edge of the system, reach some 50,000 AU away.

90377 Sedna

A lonely world, orbiting the sun up to possibly 937 AU away, Sedna is a dwarf planet discovered in 2003 by the astronomer Mike E Brown.

Sedna is the only known large dwarf planet of its size not to have a moon, which is weird. Sedna is approximately 1000km across, up to 900km minimum, and rotates once every 10 hours.

Sedna is remarkably odd because of its extremely elongated orbit, and high perihelion. There was no chance in hell Neptune could have interacted with Sedna, ever - if you interact with something, it always comes back to where you interacted with it from. Something interacted with Sedna as close as 76 AU from the Sun, and brought Sedna onto this orbit.

Sedna was found when it was 90 AU from the sun, making its discovery a fluke. Astronomers knew that if it was any further, it would have not been spotted. It was the furthest known object in the solar system when it was found. Now, that title belongs to “FarFarOut” or 2018 VG18 - approximately 125 AU away.

When Sedna was found, its rotation was thought to be up to 50 days long, possibly hinting a binary companion. Astronomers now know it is 10 hours long. Might we have missed a satellite? Perhaps.  But we will need to find it- we cannot measure mass easily without finding a satellite. Only one attempt has been made, and there’s a 25% chance we missed it.

Sedna is amongst the reddest objects in the solar system, common for trans-neptunian objects. It is a dark red, nearly as red as Mars. Tholins may be probable on Sedna but this is not known yet.

Sedna may have an atmosphere, but it is up to -237C cold, so it would be extremely thin.

Sedna may be capable of supporting a subsurface ocean.

There’s several theories for Sedna’s origin - a passing star, or even the Mythical Planet Nine that tossed it out of its circular orbit which it formed in. We don’t know, and that will have to be proven.

Simulations have shown that both of these possibilities are likely, but following the discovery of several sednoids and past discoveries, the Planet Nine hypothesis is more likely for Sedna’s origin.

Sedna will come to perihilion in 2075-76, and this is a great opportunity to learn about the primitive early solar system, as Sedna will be well preserved due to its extreme distance and coldness. Mike Brown, Sedna’s discoverer, thinks that Sedna is the most scientifically important discovery of a TNO to date.

Sedna is likely to prove several theories right and wrong about the early solar system. It’s often called an inner-Oort Cloud object, or a Detached Object because we don’t know about it. We don’t know one bit and we can’t answer that without a probe.

2018 VG18

2018 VG18  (Ending 2018 With Something "Far Out" ~ 18 Dec 2018, Philip Sedgwick)

Perhaps you’ve encountered the recent Internet articles regarding the recent realization of the most-distant planet in the solar system. Here’s what we know as of now...

In the search for Planet Nine, astronomers recently discovered a body, 2018 VG18, that is now the most distant “planet” from the Sun. Granted it is a “dwarf” planet. Then again, so is Pluto... and Ceres, so it’s a planet. Though it was discovered on November 10th, the announcement and preliminary data only now inches into public cyberspace.

It should be noted there are other Kuiper Belt Objects significantly farther out in our solar system. They, however, are not “planets.” Some of them hold extreme orbits exceeding the comprehensible. Consider that one known object orbits our Sun in an estimated orbit of 59,000 years!

2018 VG18, colloquially referred to by astronomers as “Far Out” now stands some 120 AU from Sun, 24 AU more distant than Eris. Given one Astronomical Unit is the distance from the Earth to the Sun that is far out!

According to astronomical criteria, it IS a dwarf planet weighing in with an estimated diameter of 310 miles.

To be clear, most of the current orbital data for Far Out is subject to refinement. We do know that its heliocentric node crosses the ecliptic at 7 Sag 27 - a data bit that should be secure. So that can be used for Sabian Symbol speculations about Far Out.

Based upon current data and subject to refinement, Far Out’s orbital period takes 929.43 years to complete.

Where is it and where is this new planet in my chart? On Christmas Eve Far Out transits 13 Gemini 01, retrograde. As for your chart, “Caution, Will Robinson.” While it is technically possible to run an ephemeris using our groovy software programs, other than the immediate positions, the data is likely inaccurate. It will take a significant time to stabilize the orbit so that we can accurately determine natal positions.

As well, the object cannot be formally named until its orbit is refined. As such, it will likely be quite a while before astronomers assign the name for Far Out. In the meantime, we can speculate this will be a significant body, given its announcement on the heels of a Jupiter conjunction to it at the time of declaration. And next year, Ceres transits Far Out three times, though we cannot yet say exactly when. However, we will know approximately when, and given the collective advocacy occurring at those times, more astrological flavoring can be sampled.

Tis the holiday season so brevity in posts is better. Let me wish all my readers and followers the absolutely best of the holiday season and here’s to enthusiasm for the new year! Happy Sun to the Galactic Center. May you download the best of the information in the galactic pipeline.

Finally, if there were ever a time and reason to schedule a consultation to start the new year, the announcement of the existence of Far Out is it. Click on the links below to schedule, order a Galactic Report, and/or ask quick questions to pressing life questions.
