Our Alarmingly Close Shave with an Asteroid

The video discusses the recent near-miss of asteroid 2017 OO1 with Earth, highlighting the challenges in detecting smaller asteroids and the potential damage they can cause. It also covers efforts by NASA and ESA to develop asteroid deflection missions to prevent future impacts. Additionally, the video explores the search for extraterrestrial life on icy planets and moons, emphasizing the difficulties posed by their lack of atmospheres and the potential for rapid temperature changes that could prevent habitability.

What was the size range of Asteroid 2017 001 that passed close to Earth?

• 100 to 150 meters

• 35 to 75 meters

• 10 to 20 meters

• 200 to 300 meters

Why is it difficult to detect smaller asteroids?

• They are too far away

• They do not reflect much light

• They are too bright

• They move too slowly

What is the goal of the Asteroid Impact and Deflection Assessment Mission?

• To capture an asteroid

• To study asteroid composition

• To destroy asteroids

• To change the path of an asteroid

What is essential for life to evolve and survive on other planets?

• Thick atmosphere

• Liquid water

• High temperatures

• Strong magnetic field

What happens to icy worlds when their parent star becomes hotter?

• They remain icy

• They develop thick atmospheres

• They gradually warm up

• They become intensely hot

Why do icy planets and moons struggle to retain heat?

• They have thick atmospheres

• They are too close to their star

• They reflect too much energy

• They have too much water

What is the Goldilocks zone?

• A region with just the right conditions for liquid water

• A region with no atmosphere

• A region too hot for life

• A region too cold for life
