The video explores the potential existence of Planet 9, a sizable object in the Kuiper Belt that may explain the unusual clustering of dwarf planet orbits. It is hypothesized to have a large orbit, taking 20,000 years to circle the sun, and is estimated to be four times the size of Earth with a mass ten times greater. Planet 9 might be closer than previously thought, possibly coming within 200 astronomical units of Earth. Its gravitational pull could also influence other objects in the Kuiper Belt, forcing them into perpendicular orbits.

What evidence suggests the existence of Planet 9?

• The alignment of the Milky Way

• The presence of a black hole

• The clustering of orbits in the Kuiper Belt

• The discovery of a new star

How long does it take for Planet 9 to complete one orbit around the sun?

• 10,000 years

• 20,000 years

• 50,000 years

• 5,000 years

What is the estimated size of Planet 9 compared to Earth?

• Twice the size of Earth

• Four times the size of Earth

• Half the size of Earth

• The same size as Earth

How close could Planet 9 potentially come to Earth?

• 100 astronomical units

• 400 astronomical units

• 200 astronomical units

• 300 astronomical units

What effect might Planet 9's gravity have on other objects in the Kuiper Belt?

• It may force them into perpendicular orbits

• It could eject them from the solar system

• It could cause them to collide with each other

• It might pull them closer to the sun
