Pluto Bukan Planet Lagi? | Sistem Tata Surya | SeKiLas

Summary

In this engaging video, the speaker humorously discusses the notorious traffic congestion in Jakarta, joking about wanting to move to another planet due to the overwhelming population. The video then transitions into an educational segment about Pluto, explaining its reclassification from a planet to a dwarf planet by the International Astronomical Union in 2006. The speaker highlights Pluto's inability to meet one of the three criteria required to be considered a planet. The video ends with a lighthearted discussion about why hair turns gray with age and why some young people get gray hair early.

Takeaways

• 😀 The traffic in Jakarta is getting worse, with congested roads even on highways, making the daily commute a struggle.
• 😀 The population of Earth has surpassed 8 billion, which might make some people wonder if moving to another planet is an option.
• 😀 The script humorously contemplates the idea of moving to another planet like Mercury, Venus, or Mars to escape Earth’s overcrowding.
• 😀 Pluto was once considered the ninth planet in our solar system, but it was reclassified as a 'dwarf planet' in 2006 by the International Astronomical Union (IAU).
• 😀 Pluto no longer meets all three requirements to be considered a planet: it doesn't clear its orbit of other objects.
• 😀 Pluto only meets two of the three planetary criteria: it orbits the Sun and has a spherical shape, but it doesn't clear its orbit of other objects.
• 😀 Pluto's small size and weak gravity (only 1/15th of Earth's gravity) prevent it from clearing its orbit, which is why it doesn't qualify as a planet.
• 😀 Due to Pluto's weak gravity, a 75 kg object on Earth would weigh only 5 kg on Pluto.
• 😀 Earth has an atmosphere that protects us from space debris, preventing frequent meteor showers, unlike Pluto which lacks such protection.
• 😀 Because of its inability to support life and lack of an atmosphere, Pluto is considered uninhabitable for living beings.
• 😀 The script also mentions the phenomenon of hair turning white with age, leading into a lighthearted inquiry about why young people can sometimes get gray hair, though this part transitions into a musical break.

Q & A

Why is Jakarta experiencing heavy traffic?

Jakarta faces heavy traffic due to its growing population and increasing number of vehicles on the road, including cars, motorcycles, buses, and trucks. The traffic remains congested even on toll roads.

What is the current population of Earth?

The current population of Earth is over 8 billion people.

Why does the speaker suggest moving to another planet?

The speaker humorously suggests moving to another planet as a way to escape the heavy traffic on Earth, specifically in Jakarta.

Why was Pluto removed from the list of planets in the solar system?

Pluto was removed as a planet in 2006 by the International Astronomical Union (IAU) because it did not meet all three criteria for being a planet: it doesn't clear its orbit of other objects, and its size is too small to exert enough gravitational pull.

What are the three criteria for an object to be considered a planet?

The three criteria for an object to be classified as a planet are: it must orbit the Sun, it must be nearly round in shape, and it must be able to clear its orbit of other objects.

Why does Pluto not meet the third criterion for being a planet?

Pluto does not meet the third criterion because its size is too small and its gravity is too weak to clear other objects from its orbit. Its gravitational force is only 1/15th of Earth's, which is not enough to clear its orbit.

How does the gravity on Pluto compare to Earth's gravity?

Pluto's gravity is much weaker than Earth's. An object that weighs 75 kg on Earth would weigh only about 5 kg on Pluto due to its lower gravitational pull.

What role does Earth's atmosphere play in protecting life on the planet?

Earth's atmosphere protects life by shielding us from space debris and harmful meteorites. Without it, Earth would be constantly bombarded with meteor showers.

Can Pluto support life?

No, Pluto cannot support life due to its lack of a substantial atmosphere and the extremely cold temperatures. It is classified as a dwarf planet.

What happens to a person's hair color as they age?

As people age, their hair color gradually changes to gray or white due to the decrease in melanin production. This is a natural part of the aging process.
