** The **Kuiper Belt Object (KBO)** 1781342345, also known as **Eris**, is a dwarf planet located in the outer reaches of the **Solar System**, a member of the **Kuiper Belt**, a region of icy bodies and other small celestial objects beyond the **Orbital Zone** of Neptune. ## Overview In 2005, the discovery of **Eris** sparked a debate about the definition of a planet, leading to the reclassification of **Pluto** and the establishment of a new category for dwarf planets. **Eris** is a fascinating object that provides insights into the formation and evolution of the **Solar System**. With a highly eccentric orbit, **Eris** takes approximately 557 Earth years to complete one rotation around the Sun. Its surface temperature is estimated to be around -233°C, making it one of the coldest objects in the **Solar System**. **Eris** is a member of the **Kuiper Belt**, a region of icy bodies and other small celestial objects beyond the **Orbital Zone** of Neptune. The **Kuiper Belt** is thought to be a reservoir of small, icy bodies that were left over from the formation of the **Solar System**. **Eris** is one of the largest objects in the **Kuiper Belt**, with a diameter of approximately 2,326 kilometers. Its size and mass are comparable to those of **Pluto**, leading to the debate about the definition of a planet. ## History/Background The discovery of **Eris** was announced on July 29, 2005, by a team of astronomers led by **Michael Brown**. The discovery was made using the **Palomar Observatory** in California, USA. **Eris** was initially thought to be larger than **Pluto**, leading to a debate about the definition of a planet. The International Astronomical Union (IAU) eventually redefined a planet as a celestial body that: 1. Is in orbit around the Sun. 2. Has sufficient mass to assume a hydrostatic equilibrium shape (i.e., it is nearly round in shape). 3. Has cleared the neighborhood around its orbit. **Eris** does not meet the third criterion, as its orbit overlaps with that of other objects in the **Kuiper Belt**. ## Key Information **Eris** is a dwarf planet with a highly eccentric orbit. Its orbit takes it as close as 37.8 astronomical units (AU) from the Sun and as far as 95.6 AU from the Sun. One astronomical unit is the average distance between the Earth and the Sun. **Eris** has a highly inclined orbit, tilted at an angle of 44 degrees relative to the **Ecliptic**. Its surface is thought to be composed of frozen methane and nitrogen ices, with a possible presence of rocky material. **Eris** has a moon, **Dysnomia**, which was discovered in 2005. **Dysnomia** is a small, irregularly shaped moon with a diameter of approximately 700 kilometers. ## Significance The discovery of **Eris** led to a reevaluation of the definition of a planet. The IAU's new definition has helped to clarify the distinction between planets and dwarf planets. **Eris** provides insights into the formation and evolution of the **Solar System**, particularly in the outer reaches of the **Solar System**. Its highly eccentric orbit and surface composition make it an interesting target for future studies. **INFOBOX:** - Name: Eris - Type: Dwarf Planet - Date: July 29, 2005 - Location: **Kuiper Belt** - Known For: Discovery of a dwarf planet and redefinition of a planet **TAGS:** Dwarf Planet, Kuiper Belt, Solar System, Eris, Pluto, Michael Brown, Palomar Observatory, International Astronomical Union, Orbital Zone, Neptune, Ecliptic, Dysnomia.

This **KBO** is one of the many small, icy bodies that inhabit the **Kuiper Belt**, a region of the **Solar System** that extends from the orbit of **Neptune** to a distance of about 55 astronomical units (AU) from the **Sun**. The **KBO 2007 OR10** is a fascinating object that has provided scientists with valuable insights into the formation and evolution of the **Solar System**. The **Kuiper Belt** is a vast, disk-shaped region of icy bodies, rocky objects, and other small celestial entities that are thought to be remnants from the formation of the **Solar System**. These objects are remnants from the early days of the **Solar System**, when the **Sun** and the planets were still in their formative stages. The **Kuiper Belt** is a treasure trove of information about the early history of the **Solar System**, and the study of these objects has helped scientists to better understand the formation and evolution of our cosmic neighborhood. ### History/Background The discovery of the **Kuiper Belt Object (KBO) 2007 OR10** was announced on August 4, 2007, by astronomers using the **Palomar Observatory** in California. The object was discovered using a combination of **telescopes** and **computer algorithms** that allowed scientists to identify and track the motion of small, faint objects in the **Kuiper Belt**. The **KBO 2007 OR10** was initially classified as a **Kuiper Belt Object**, but subsequent observations revealed that it was a more complex and fascinating object than initially thought. ### Key Information The **Kuiper Belt Object (KBO) 2007 OR10** is a small, icy world with a diameter of approximately 700 kilometers (435 miles). Its surface is thought to be composed of a mixture of water ice, methane, and other frozen volatiles. The object has a highly eccentric orbit, which takes it from a distance of about 35 AU from the **Sun** to a distance of about 55 AU from the **Sun**. This orbit is highly inclined, with an inclination of about 29 degrees relative to the **ecliptic plane**. The **KBO 2007 OR10** has a highly reflective surface, with an albedo (reflectivity) of about 0.8. This suggests that the object's surface is composed of highly reflective materials, such as water ice and methane. The object's surface temperature is thought to be around -233°C (-391°F), which is much colder than the surface temperature of the **Earth**. ### Significance The **Kuiper Belt Object (KBO) 2007 OR10** is a significant object in the study of the **Solar System** because it provides scientists with valuable insights into the formation and evolution of our cosmic neighborhood. The object's highly eccentric orbit and highly inclined inclination suggest that it may have originated from a different region of the **Solar System**, such as the **Oort Cloud** or the **Scattered Disc**. The study of the **KBO 2007 OR10** has also provided scientists with valuable information about the composition and structure of the **Kuiper Belt**. The object's highly reflective surface and icy composition suggest that the **Kuiper Belt** is a region of the **Solar System** that is rich in water ice and other frozen volatiles.
