Our Solar System Might Have TWO Hidden Planets

The video discusses the reclassification of Pluto as a dwarf planet and the potential existence of hidden planets in our solar system, such as Planet 9 and Planet 10. It explores the Kuiper Belt, the hypothetical Oort Cloud, and the concept of rogue planets. The challenges of discovering these distant planets are highlighted, including the use of techniques like gravitational microlensing.

What significant change occurred in 2006 regarding Pluto?

• It was discovered to have rings.

• It was declared a rogue planet.

• It was reclassified as a dwarf planet.

• It was found to be larger than Earth.

What is the Kuiper Belt?

• A collection of rogue planets.

• A disk of rocky leftovers orbiting the sun.

• A giant sphere of icy space rocks.

• A region of space with many comets.

What is the proposed mass range for Planet 9?

• 10 to 20 times the mass of Earth

• 1 to 2 times the mass of Earth

• 5 to 10 times the mass of Earth

• Equal to the mass of Jupiter

What is the Oort Cloud?

• A belt of comets near the sun.

• A confirmed region of space with many asteroids.

• A cluster of stars near Proxima Centauri.

• A hypothetical sphere of icy bodies surrounding the solar system.

What are rogue planets?

• Planets that have been ejected from their solar system.

• Planets that orbit two stars.

• Planets that have rings.

• Planets that are larger than Jupiter.

What makes detecting Planet 9 challenging?

• It is too bright to observe directly.

• Its orbit is too close to the sun.

• It is too far and dim for current telescopes.

• It is hidden behind the moon.

Which method could potentially help in detecting distant planets like Planet 9?

• Transit method

• Gravitational microlensing

• Direct imaging

• Spectroscopy
