Pluto: Still Not A Planet

The video discusses the European Space Agency's JUICE mission to explore Jupiter and its moons, highlighting the engineering challenges and scientific objectives. It also covers the ongoing debate about Pluto's planetary status, with a proposal to redefine what constitutes a planet, potentially adding over 100 new planets to our solar system. The video concludes with acknowledgments to supporters.

What is the primary goal of the JUICE mission?

• To investigate Saturn's rings

• To analyze the Sun's atmosphere

• To study Jupiter and its moons

• To explore Mars and its moons

What is one of the main challenges in designing the JUICE spacecraft?

• Jupiter's weak magnetic field

• The lack of water on Jupiter

• The need for nuclear power

• Jupiter's strong magnetic field and radiation belts

What new definition did the New Horizons team propose for a planet?

• A body that orbits the sun and has cleared its orbit

• A body less massive than a star that has never experienced nuclear fusion

• A body that is larger than Earth

• A body that has rings and moons

According to the current IAU definition, what is NOT a requirement for an object to be considered a planet?

• It must have enough mass to be a sphere

• It must clear its orbit of debris

• It must have rings

• It must orbit the sun

What is the likelihood of the IAU accepting the new planet definition proposed by the New Horizons team?

• Very likely

• Unlikely

• No chance

• Already accepted
