  Orcus (minor planet 90482)
The name Orcus, from a Roman god of the dead and another name for the Greek deity Hades, was approved by the International Astromical Union (IAU) on Nov. 22, 2004.
Orcus was discovered in images taken on Feb. 17, 2004 (nearly 74 years to the day after Pluto was found) by Mike Brown (CalTech), Chad Trujillo (Gemini Observatory), and David Rabinowitz (Yale) – the same team that discovered the largest known KBO, Eris (formerly called 2003 UB313).
The diameter of Orcus has been put at about 1,600 km (compared with Pluto's 2,300 km) but this is only an estimate because of uncertainty in the object's albedo (relectivity).

 90482 Orcus
Asteroid 90482, Orcus, a trans-Neptunian object, was discovered on February 17, 2004 by Chad Trujillo, Michael Brown and David Rabinowitz at Palomar Observatory near Pauma Valley, California.
Orcus was named for the Roman god of death, whom the Greeks called Thanatos and who is sometimes identified with Pluto.
Donald Trump has Orcus in the tenth house, conjunct the North Node, sextile Heracles (to contend with) and Deucalion, and opposite the Moon (the public), Lilith and the South Node.

Orcus and Pluto follow similar but differently oriented orbits as shown on the diagram (Orcus in blue, Pluto in red, Neptune in grey, positions as of April 2006).
Orcus is approaching the aphelion (2019) while Pluto has passed the perihelion (1989) and is descending toward the ecliptic.
Orcus presents a neutral colour as opposed to the second largest known plutino, Ixion (<820km) which is red, had no water ice discovered so far and has albedo higher than Orcus.

In Roman mythology, Orcus was a god of the underworld, punisher of broken oaths, more equivalent to Pluto than to the Greek Hades, and later identified with Dis Pater.
The so-called "Tomb of the Orcus", an Etruscan site at Tarquinia, is a misnomer, resulting from its first discoverers mistaking as Orcus a hairy, bearded giant that was actually a figure of a Cyclops.
From Orcus' association with death and the underworld, his name came to be used for demons and other underworld monsters, particularly in Italian where orco refers to a kind of monster found in fairy-tales that feeds on human flesh.

While some references use Hades somewhat interchangeably with Orcus, these are distinctive astronomical/astrological bodies that should not be confused.
Most notably, Orcus (killer by some translation) prevails as the deity that hears the words spoken in oaths.
The heliocentric node of Orcus is 28 Sagittarius 32, aligned with the Galactic Center.
