Summary of Planeta 9 - ¿Cuándo Podremos verlo?

00:00:00 - 00:15:00

The video titled " Planeta 9 - ¿Cuándo Podremos verlo?" features a speaker discussing the existence of Planeta 9, a hypothetical ninth planet in our solar system. The speaker explains that scientists at Caltech are investigating the possible properties and location of the planet, with a probability of existence estimated at 99.9%. The video covers the background of this search, starting with the discovery of Uranus in 1781 and the subsequent realization that its unusual motion could be explained by the existence of a previously unknown planet, Neptune. The speaker also discusses his own work at Caltech and the challenges of discovering such a planet, including the vast distance involved and the difficulty of detecting a relatively small object against the vastness of space.

• 00:00:00 In this section, the speaker discusses the existence of a potential ninth planet in our solar system, referred to as Planeta 9. He explains that the probability of the planet's existence is estimated to be 99.9%, and that scientists at Caltech are investigating its possible properties and location. The speaker explains the background of this search, starting with the discovery of Uranus in 1781 and the subsequent realization that its unusual motion could be explained by the existence of a previously unknown planet, Neptune. He also talks about the recent discovery of the Kuiper Belt, a region of icy debris beyond Neptune's orbit, and how it has influenced our understanding of the solar system and the possibility of another planet beyond Neptune. The speaker then discusses his own work at Caltech, which includes studying this hypothetical planet and its potential location in the sky. He also talks about the challenges of discovering such a planet, including the vast distance involved and the difficulty of detecting a relatively small object against the vastness of space. The speaker concludes by emphasizing the importance of continued research and exploration in the pursuit of scientific discovery.
• 00:05:00 In this section of the video, the hosts of the "Planeta 9 - ¿Cuándo Podremos verlo?" podcast discuss the discovery of the second object to be identified in the Kuiper Belt, which they call "el segundo objeto identificado del cinturón Kuiper". They explain that the discovery was originally made in 1992 and that it is located at a distance of 45-50 au, and that it is not heading towards the sun like Pluton, but rather is moving in a "slow and steady" manner across the sky. The hosts discuss composer Alex Korb's findings that the orbit of the object points in the same direction as all the other objects in the Kuiper Belt, and the possibility that there may be some elsewhere in the sky that are currently unseen. They also discuss the controversy surrounding the discovery, with some scientists skeptical of its significance.
• 00:10:00 In this section, the speaker discusses the concept of planet 9 and its unique characteristics. The speaker argues that this planet's evolutionary model is intriguing and that it has the power to orbit distant objects. The speaker highlights that although the planet's orbit is complex and requires computers, its key is the expectation that such objects exist, and they can be observed. The speaker argues that planet 9 is unique, and there is no other natural mechanism that can generate such inclined orbits. The speaker also notes that the planet 9 has an elongated orbit and that the planner is still to be found.
• 00:15:00 In this section of the video, the speaker discusses the possibility of finding and naming Planeta 9. When we move away from the sun, there is a large amount of space to hide objects, making it possible to conceal something as large as a planet or as small as we want. If Planeta 9 is found, the question arises as to who has the right to name it. The speaker suggests that David Bowie could be a suitable name for the planet, as there is an online petition to name it after him on change.org. Although the speaker acknowledges that this idea is not taken seriously, the possibility of naming the planet after famous figures such as Jupiter, Saturn, Urano, Neptune, and David Bowie is discussed.
