Chad Trujillo

Chadwick A. "Chad" Trujillo (born November 22, 1973), is the co-discoverer of 2003 UB313, which he claims to be the Tenth Planet. Trujillo works with computer software and has examined the orbits of the numerous trans-Neptunian objects (TNOs), which is the outer area of the solar system that he specialized in. In late August, 2005, it was announced that Trujillo, along with with Michael E. Brown and David L. Rabinowitz), had discovered 2003 UB313. This was the first TNO known to be larger than the planet Pluto. ...

The solar system comprises our Sun and the retinue of celestial objects gravitationally bound to it. Traditionally, this is said to consist of the Sun, nine planets and their 158 currently known moons; however, a large number of other objects, including asteroids, meteoroids, planetoids, comets, and interplanetary dust, orbit the Sun as well. Although the term "solar system" is frequently applied to other star systems and the planetary systems which may comprise them, it should strictly refer to our system specifically: the wor ...

2003 EL61 (also written 2003 EL61), nicknamed "Santa" (non-official designation), is a very large and unusual Kuiper belt object recently discovered by Mike Brown et al. at Caltech in the United States. The nickname stems from its discovery just after Christmas, on December 28, 2004, although the Caltech team had acquired images of it starting May 6, 2004. The nickname is only temporary and will not be the official name of the object. IAU guidelines dictate that the object will be named after a c ...

2003 UB313 (center) and moon (right of center). Keck Observatory. 2003 UB313 is a trans-Neptunian object (TNO) which California astronomers at Mount Palomar observatory describe as "definitely bigger" than the planet Pluto. The object has already been dubbed the tenth planet by the discoverers, NASA, and some media outlets, but it is not yet clear whether it will be widely accepted as a new planet or not. It has at least one moon. No official name for ...

After the election, Quigley was no longer needed and her relationship with the First Lady ended. But, the following year, Hinckley shot Reagan. Nancy grew concerned and asked Quigley if she could have foreseen, and possibly prevented, the assassination attempt. Quigley answered affirmatively, that had she been looking, she would have known. From that moment on, Quigley became Nancy's most trusted confidant. Quigley concluded that Reagan's charts were very similar to assassinated President Abraham Lincoln's astrological signs, with bot ...

According to their location, the objects in the solar system are divided into three zones: Zone I or the inner solar system, including terrestrial planets and the Main belt of asteroids; Zone II, including the giant planets, their satellites and the centaurs, and Zone III, or the outer solar system, comprising the area of the Trans-Neptunian objects including the Kuiper Belt, the Oort cloud, and the vast region in between.

Sedna was discovered during a survey conducted with the Samuel Oschin telescope at Palomar Observatory near San Diego, California (USA) and was observed within days on telescopes from Chile, Spain, and the USA (Arizona, and Hawaii). NASA's orbiting Spitzer Space Telescope was also pointed toward the object, but could not detect it — putting an upper-bound on its diameter at roughly three-quarters that of Pluto. Because of its cold, distant nature, and because all other planets of the Solar system are named after (Roman and Greek) go ...

José Luis Ortiz Moreno, an astronomer at the Sierra Nevada Observatory in Spain, and colleagues Francisco José Aceituno Castro and Pablo Santos-Sanz announced the discovery of the object on July 25, 2005, when they re-analysed observations they had made on March 7, 2003. They then scoured older archives (a process known as precovery) and found the object in images dating back to 1955. Ortiz's group announced their discovery on July 27, 20 ...

The discoverers have argued that Sedna is actually the first observed body belonging to the Oort cloud, saying that it is too far out to be considered a Kuiper belt object. Because it is a great deal closer to the Sun than was expected for an Oort cloud object, and has an inclination roughly in line with the planets and the Kuiper belt, they describe the planetoid as being an inner Oort cloud object, situated in the disc reaching from the K ...

Sedna has an estimated diameter of between 1180 and 1800 kilometres (730 to 1120 miles). At the time of its discovery it was the largest object found in the solar system since Pluto was discovered in 1930. It is now generally believed to be the 5th largest known trans-Neptunian object after 2003 UB313, Pluto, 2005 FY9, and 2003 EL61. The planetoid is so far from the Sun that the temperatur ...

The current hypothesis of solar system formation is the nebular hypothesis, first proposed in 1755 by Immanuel Kant and independently formulated by Pierre-Simon Laplace. It states the solar system was formed from a gaseous cloud called the solar nebula. It had a diameter of 100 AU and was 2-3 times the mass of the Sun. Over time, a disturbance, possibly a nearby supernova, sent shock waves into space, which squeezed the nebula, pushing more and more of its matter inward until gravitational forces overcame its internal gas pressure and it beg ...

The solar system is located in the Local Fluff of the Milky Way galaxy, a spiral galaxy with a diameter of about 100,000 light years containing approximately 200 billion stars, of which our Sun is rather large and bright. (The vast majority of stars are red dwarfs; our Sun is placed near the middle of the Hertzsprung-Russell diagram, but stars larger and hotter than it are rare, whereas stars dimmer and cooler than it are very common, although we can observe on ...

The Sun (astronomical symbol ☉) is a main sequence G2 star that contains 99.86% of the system's known mass. Its two largest orbiting bodies, Jupiter and Saturn, account for 91% of the remainder (the Oort Cloud might hold a substantial percentage, but as yet its existence is unconfirmed). In broad terms, the charted regions of our solar system consist of the Sun and its planetary system: the eight bodies in relatively unique orbits (commonly called planets or major planets) and two belts of smaller objects (which can be called minor ...

Sedna has a highly elliptical orbit, with its aphelion estimated at 942 AU and its perihelion at about 76.1 AU. At its discovery it was approaching perihelion at about 90 AU from the Sun. It was the farthest from the Sun that any solar system object had up to then been observed, although some objects like long-period comets originally observed at closer distances were most likely further from the Sun than Sedna but too dim to be observed. 2003 UB313 was later detected at 97 AU. Sedna's orbit takes about ...
