Evidence for the hypothetical existence of Planet 9 increases

The video discusses the potential existence of Planet 9, a hypothesized planet in our solar system. Co-authored by Michael Brown, the study suggests that Planet 9 is unlikely to be a fluke, with a very low chance of the observed clustering of objects being coincidental. The new study proposes that Planet 9 is closer to the sun than previously thought, making it brighter and easier to detect. It may be a rocky super Earth or a gaseous mini Neptune. The planet likely formed near Uranus and Neptune but was displaced by Saturn's gravity. Future observations may confirm its existence using data from the Vera Rubin Observatory.

What led to the hypothesis of Planet 9's existence?

• The demotion of Pluto to a dwarf planet

• The unusual positioning of ice asteroids and cometary cores

• The discovery of a new planet in the Kuiper Belt

• The gravitational pull of Jupiter

What does the recent study suggest about the likelihood of the unusual clustering being a fluke?

• It is definitely not a fluke

• There is a 0.4% chance it is a fluke

• There is a 50% chance it is a fluke

• It is highly likely to be a fluke

How has the new study changed the understanding of Planet 9's orbit?

• It is now believed to be further from the Sun

• It is now believed to be closer to the Sun

• Its orbit is now thought to be more circular

• Its orbit is now thought to be more elliptical

What are the possible characteristics of Planet 9 according to Brown's analysis?

• A terrestrial planet like Mars

• A small icy planet like Pluto

• A gas giant like Jupiter

• A rocky super Earth or a gaseous mini Neptune

Where does Brown hope to find evidence of Planet 9?

• In data from the Mars Rover

• In data from the Hubble Space Telescope

• In images from the Vera Rubin Observatory

• In observations from the International Space Station
