The Hubble Space Telescope Confirms Tenth Planet Discovery Reveals It's Larger Than Pluto In a fascinating exploration of space discoveries, this YouTube video centers on the Hubble Space Telescope's findings related to the possible confirmation of a tenth planet within our solar system. Specifically, it discusses the intriguing case of Eris, a dwarf planet that appears to challenge our understanding of solar system dynamics and classifications.

Key Insights from the Video​

  1. Discovery of Eris: Eris, often referred to by its nickname Xena, initially appeared to be larger than Pluto based on early measurements. It was discovered in 2005 by a team including Mike Brown, who detailed how the Hubble Telescope was pivotal in obtaining precise measurements of Eris's size. This led to the realization that while its mass was about 27% greater than Pluto's, its diameter was actually smaller—about 1490 miles compared to Pluto's 1422 miles.
  2. The Dwarf Planet Classification: The ongoing debate about whether Eris qualifies as a planet concluded when it was categorized as a dwarf planet alongside Pluto. This revelation helped reinstate Pluto's status as the largest known dwarf planet, countering earlier assertions of Eris's superiority in size.
  3. Surface Observations: The video emphasizes that Eris is exceptionally bright, possibly due to the frost on its surface, which may result from methane gas emissions or extreme cold temperatures in its distant orbit. This brightness can skew perceptions of its size, complicating measurement efforts historically conducted from Earth.
  4. Scientific Implications: The findings have broader implications for our understanding of celestial bodies beyond Neptune. The Hubble's observations have reshaped our knowledge of the outer solar system, prompting renewed discussions on how we define planets and their classifications in light of new discoveries.
  5. Future Explorations: While Eris currently lacks any spacecraft visits, the video suggests that this could change. It highlights advancements in technology and research, particularly the potential for future missions to Eris that could yield deeper insights into its geology and atmosphere.

    Conclusion​

    The discussions surrounding Eris exemplify the evolving nature of astronomical classification and the discoveries made through tools like the Hubble Space Telescope. As research continues, the quest to understand our solar system grows ever deeper and more complex. What do you think about these discoveries? Have you followed the debates regarding Pluto and Eris?
