In this article, we will delve deeper into the exploration of Eris by the Hubble Space Telescope and examine what we have discovered so far about this enigmatic world.
Introduction: Eris, the Dwarf Planet that Remains a Mystery
The exploration of Eris by Hubble Space Telescope is a fascinating topic that has captured the attention of many space enthusiasts across the globe. Eris is one of the largest dwarf planets in our solar system, located beyond Neptune's orbit. It was discovered in 2005 and named after the Greek goddess of discord and strife.
The Discovery and Naming of Eris
Eris was first spotted by astronomers Mike Brown, Chad Trujillo, and David Rabinowitz using images taken from Palomar Observatory in California. They detected a bright object moving slowly across the sky, which they initially thought was another Kuiper Belt object. However, further observations revealed that it was much larger than any other known object in this region.
After its discovery, there was much debate about whether to classify Eris as a planet or not. Ultimately, it was designated as a dwarf planet due to its size and location within an area filled with other similar objects.
The Mystery Surrounding Eris
Despite being studied extensively over the past decade since its discovery, much remains unknown about this enigmatic dwarf planet. One particular mystery is why it has such an elongated orbit compared to other objects in our solar system.
Another intriguing aspect of Eris is its surface composition. From ground-based observations using infrared telescopes, scientists have determined that it is covered with methane ice mixed with nitrogen frost and traces of carbon monoxide ice.
However, these findings are limited due to atmospheric interference on Earth's surface during observations. This makes studying Eris from space even more critical for unlocking its secrets.
