Sedna, small body in the outer solar system that may be the first discovered object from the Oort cloud. Sedona is home to an all-natural rock waterslide.One of the only natural waterslides in the world resides right here in Arizona. 5 months, but it turned out to be an incorrect theory. It takes a long time for Sedna to orbit the Sun, longer than any other known object in the solar system. If an object either impacted Sedna or drew close enough to affect its orbit, it's no longer there. Perhaps it’s even older than the planets of the Solar system…, 17 interesting facts about the Grand Canyon. Way past the orbit of Pluto, there's an object orbiting the Sun in a highly eccentric orbit. Sedna was named after the eponymous goddess, the ruler of sea animals in the eskimo Pantheon.

[2] [3] Around 1250-1800 km in diameter , [2] Sedna takes roughly 10,500 years to orbit the Sun , much higher than most known trans-Neptunian objects. Originally, Sedna was believed to be much larger. This makes it the largest trans-Neptunian object orbiting the Sun that doesn't have its own satellite. At that time, it was the most distant object in the solar system that had ever been observed, at a distance of 13 billion km (8.1 billion miles) from the Sun. In order to qualify as a dwarf planet, a body must have enough gravity (mass) to assume a rounded shape and may not be a satellite of another body. Therefore, Sedna's surface temperature never rises above -240°C. Astronomers had thought that all objects in the outer solar system would be icy and therefore white or gray in appearance, but Sedna was almost as red as Mars. While methane snow may fall on Pluto and Triton, it's too cold for organic snow on Sedna. Another reason a year on Sedna is so long is because the body moves relatively slowly around the Sun, about 4% as fast as the Earth moves. The cultural energy of this magical place isn’t entirely due to the energy vortexes, the rich Native American history has a huge part in it. Sedna is located in the Oort Cloud, a region containing many icy objects and the theoretical source of many comets. By all accounts, Sedna is a dwarf planet. Turns out that when McDonald's moved into the area, the city officials thought that the golden yellow color of the arches would distract from the natural beauty of the area and decided that turquoise would compliment the surrounding red rock a little bit better.

Sedna was discovered in 2003 by a team of American astronomers at Palomar Observatory on Mount Palomar, California. Iron! The local year here is very, about 11.487 standart years. For this reason, Sedna is known as "Cobian", meaning shadows in Ancient Greek. The distance from Sedna to the Sun in the farthest part of the orbit exceeds the distance between the Sun and the Earth by 960 times. [2][3] It is one of the most distant known objects in the Solar System. 40-120 more objects this size should exist without us knowing, but, as they are so small and far away, they may not be discovered for a while. According to one theory, in the distant past, a wandering star or planet passed by our system, and the orbit of Sedna changed in such an unusual way due to the gravitational disturbances caused by this event. It has no satellites, so it is impossible to determine the mass of Sedna using mathematical calculations. Carved by the water in Oak Creek, the natural sandstone makes a perfect slippery slide to glide down on a hot Arizona day. Pretty odd right? Sedna is very, very distant! ThoughtCo uses cookies to provide you with a great user experience. Gravity on the surface of Sedna is weaker than on Earth for 20-35 times, according to modern estimates. Its 11000 year cycle is so long partially because it's so far out, but also because the orbit is highly elliptical rather than round. Likely candidates for such an encounter include a single passing star, an unseen planet out beyond the Kuiper belt, or a young star that was with the Sun in a stellar cluster when it formed. Sedona is so rich in art, history, and beauty it should be on the list! Because it's between 11 and 13 billion kilometers away, its surface features are a mystery. However, that pinprick of light would be bright, about 100 times brighter than the full moon viewed from Earth. Corrections? It is considered to be a likely candidate as a dwarf planet. Whether you’re looking to stay in Sedona for a while or you’re just passing through town, you’re probably curious about this magical place in the middle of Arizona. Sedna has no known moons. Apparently, Sedna looks even redder visually than Mars. Sedna was the most distant object in the Solar system known to mankind at the time of its discovery. Book a stay at the Alma de Sedona Inn for warm service and incredible red rock views. While the plotted orbit of Sedna indicates its not a moon, the world's shape is unclear. Some scientists believe that it is due to the presence of another large planet somewhere in the outer. Sedona is located at the base of an irregular row of cliffs that extends across Arizona … It's actually more of a turquoise color. Sedna was co-discovered on November 14, 2003 by Michael E. Brown (Caltech), Chad Trujillo (Gemini Observatory), and David Rabinowitz (Yale). It was discovered on November 14, 2003[1] by Mike Brown, Chad Trujillo and David Rabinowitz. The team announced the name "Sedna" before the object had been numbered, which was not proper protocol for the International Astronomical Union (IAU), but didn't raise objections. Plus guests of the Alma de Sedona receive 10% off!) No one can say for sure yet though. Updates? NASA is not currently planning any space missions to explore Sedna, but there is some talk of missions to happen when Sedna reaches perihelion again. Observations of Sedna quickly raised a number of puzzling questions. Fun Fact: Sedona is one of the coolest places in the world, but you didn’t need us to tell you that. Even. Sedna is almost identical to Ceres in size, a dwarf planet in the main asteroid belt, it’s a bit smaller than 620 miles (1.000 km) in diameter.

But it still doesn’t have this status officially. Trujillo's model of the surface composition suggests Sedna is coated with 33% methane, 26% methanol, 24% tholins, 10% nitrogen, and 7% amorphous carbon. No spacecraft will visit it in a close future for the obvious reason – it will take many decades to fly to this dwarf planet even in the nearest point of orbit and under ideal conditions. This page was last changed on 26 October 2020, at 06:05.
