SUMMARY

The discussion centers on V774104, a distant sednoid discovered in November 2015 by astronomer Scott Sheppard using the Subaru Telescope. Despite its intriguing characteristics, including an estimated size of 500 to 1000 kilometers and a distance of approximately 15.4 billion kilometers from the Sun, no astrometry has been submitted to the Minor Planet Center, resulting in a lack of publicly known orbital elements. Participants express frustration over the absence of updates regarding its orbital parameters, emphasizing the need for continued observation to establish a definitive orbit.

PREREQUISITES
  • Understanding of sednoids and their significance in astronomy
  • Familiarity with the Minor Planet Center and its role in tracking celestial objects
  • Knowledge of astronomical observation techniques, particularly using telescopes
  • Basic comprehension of orbital mechanics and parameters
NEXT STEPS
  • Research the Brown-Batygin computer modeling hypothesis related to distant celestial bodies
  • Explore the latest findings on V774104 through the Minor Planet Center's database
  • Investigate the methods used for determining orbital parameters of newly discovered objects
  • Stay updated on developments in the study of sednoids and other distant solar system objects
USEFUL FOR

Astronomers, astrophysicists, and space enthusiasts interested in the study of distant celestial objects and the ongoing research surrounding V774104 and similar sednoids.

"The discovery was announced at the November 2015".
"No astrometry has been submitted to the Minor Planet Center, so there are no publicly known orbital elements".

Hmm. This is an interesting object, one of the most distant, possibly only the third-ever discovered sednoid... and no news since initial discovery, no better orbit determination since then?

Hi, I found this. From, http://www.lunarplanner.com/asteroids-dwarfplanets/Ninth-Planet/index.html
The Brown-Batygin computer modeling hypothesis comes along with the November 10, 2015 announcement of
another recently discovered dwarf planet by Scott Sheppard, an astronomer at the Carnegie Institution for Science, designated V774104. Sheppard and colleagues made the discovery using Japan’s Subaru
Telescope in Hawaii. V774104 is currently about 15.4 billion kilometers from the Sun (103 AU)
and is estimated to be between 500 and 1000 kilometers across. (It will take at least a year to determine its orbital parameters).

Still no news on the refined orbit?

Good question, I'll see what I can find.

We are at the end of the minimum time frame for establishing orbital parameters, maybe something soon.
This site would be worth watching for developments.

Interesting. Still no news.

uo3L91 finally got its MPC designation a few months ago (now known as 2013 SY99) and it was discovered 3.5 years ago AND is ~40 au closer to the sun...so it may be awhile yet, til V774104 has an observation arc long enough to get a "page in the book".

So what are you saying? It is _not_ an alien spaceship from other stars?? My hopes are crushed... ;)
 
Of course it is an alien space ship. The aliens are merely making course adjustments to confound our ability to predict their arrival.
