Searching for Planet Nine: New Evidence and Discoveries

TLDRThis talk discusses the ongoing search for a possible ninth planet in our solar system, offering new evidence and findings. The speaker explains the history of our solar system's planets, including the demotion of Pluto, and introduces the concept of Planet Nine. The presentation also discusses the methods used in the search, such as analyzing telescope data and detecting the motion of solar system objects. While Planet Nine has not yet been found, ongoing research aims to uncover more about our solar system's outer regions.

Key insights

🪐Pluto was demoted from planet status, and recent evidence suggests the existence of a ninth planet in our solar system.

🔭Observations of the motion of solar system objects revealed a pattern that suggests the presence of a distant planet.

📷The Dark Energy Survey uses a large camera to capture images of the sky, potentially leading to the discovery of new solar system objects.

🌌The search for Planet Nine is part of a larger effort to understand the evolution and dynamics of the universe.

🌏Efforts are ongoing to analyze telescope data and detect the presence of Planet Nine in the outskirts of our solar system.

Q&A

Why was Pluto demoted from planet status?

—Pluto was demoted from planet status in 2006 due to redefined criteria for what constitutes a planet. It was reclassified as a dwarf planet.

How are solar system objects differentiated from stars and galaxies?

—Solar system objects are differentiated from stars and galaxies by their detectable motion. While stars and galaxies appear stationary, solar system objects exhibit movement that can be tracked.

What is the Dark Energy Survey and its purpose?

—The Dark Energy Survey is a project aimed at studying the evolution and dynamics of the universe. It utilizes a large camera to capture images of the sky for analysis.

How is the motion of solar system objects analyzed to search for Planet Nine?

—The motion of solar system objects is analyzed by tracking their position over time. This information is compared to predicted motions based on Newtonian gravity, potentially revealing the presence of a hidden planet.

Has Planet Nine been found yet?

—Planet Nine has not yet been discovered. Ongoing research and analysis of telescope data are being conducted to confirm its existence and location.
