** The **Kuiper Belt Object (KBO)**, also known as **Eris**, is a dwarf planet located in the outer reaches of the **Solar System**, discovered in 2005, which has sparked debate about the definition of a planet. ## Overview The Kuiper Belt is a region of the Solar System containing a vast array of small, icy bodies, including dwarf planets, asteroids, and comets. Located beyond the orbit of **Neptune**, the Kuiper Belt is thought to be a reservoir of small celestial objects that have not been perturbed into more stable orbits. In 2005, a team of astronomers led by **Michael Brown** discovered a KBO, which was initially named **Eris**. This discovery sparked a heated debate about the definition of a planet, as Eris was found to be slightly larger than **Pluto**, which had long been considered the ninth planet in our Solar System. Eris is a fascinating object that has provided scientists with valuable insights into the formation and evolution of the Solar System. Its highly eccentric 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 is also known for its highly inclined orbit, which takes it above and below the plane of the Solar System. ## History/Background The discovery of Eris was announced on July 29, 2005, by a team of astronomers from the California Institute of Technology (Caltech). The team, led by Michael Brown, used the **Palomar Observatory** in California to observe Eris, which was initially thought to be a large asteroid. However, further observations revealed that Eris was a dwarf planet, with a diameter of approximately 2,326 kilometers (1,445 miles). This discovery sparked a debate about the definition of a planet, with some arguing that Eris should be considered the tenth planet in our Solar System. In 2006, the International Astronomical Union (IAU) defined 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. According to this definition, Eris does not meet the third criterion, as its orbit overlaps with other objects in the Kuiper Belt. Therefore, Eris was reclassified as a dwarf planet, a new category of objects created by the IAU. ## Key Information * **Name:** Eris * **Type:** Dwarf planet * **Date:** Discovered on January 5, 2005 * **Location:** Kuiper Belt, outer reaches of the Solar System * **Diameter:** Approximately 2,326 kilometers (1,445 miles) * **Orbital Period:** 557 Earth years * **Surface Temperature:** Estimated to be around -233°C (-391°F) Eris is a fascinating object that has provided scientists with valuable insights into the formation and evolution of the Solar System.

** The **Kuiper Belt Object (KBO)**, also known as **Eris**, is a dwarf planet located in the outer reaches of the **Solar System**, beyond the orbit of **Neptune**. ## Overview The **Kuiper Belt** is a region of our **Solar System** that contains a vast array of small, icy bodies, including dwarf planets, asteroids, and comets. The **Kuiper Belt** is thought to be a reservoir of small celestial objects that were left over from the formation of the **Solar System**. One of the most notable objects in the **Kuiper Belt** is **Eris**, a dwarf planet that was discovered in 2005. **Eris** is a fascinating object that has helped scientists learn more about the formation and evolution of our **Solar System**. Its discovery has also raised questions about the definition of a planet and the criteria for what constitutes a planet. **Eris** is a member of a new class of objects known as **dwarf planets**, which are celestial bodies that are large enough to be rounded by their own gravity but have not cleared their orbits of other objects. ## History/Background The discovery of **Eris** was announced in 2005 by a team of astronomers led by Mike Brown of the **California Institute of Technology**. The team was searching for objects in the **Kuiper Belt** that were similar in size to **Pluto**, but with more extreme orbits. **Eris** was found to have a highly eccentric orbit that 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**. The discovery of **Eris** sparked a debate about the definition of a planet. The **International Astronomical Union (IAU)** was forced to re-examine its definition of a planet, which had been in place since 2006. The new definition states that a planet must "clear the neighborhood around its orbit," meaning that it must be the dominant object in its orbit. **Eris** does not meet this criterion, as its orbit overlaps with that of other objects in the **Kuiper Belt**. ## Key Information **Eris** is a small, icy world with a diameter of approximately 2,326 kilometers (1,445 miles). It has a highly eccentric orbit that takes it as close as 37.8 AU from the **Sun** and as far as 95.6 AU from the **Sun**. **Eris** has a surface composed primarily of frozen methane and nitrogen, which gives it a highly reflective surface.
