The video discusses NASA's Double Asteroid Redirection Test (DART) mission, which aims to test the possibility of altering an asteroid's course by crashing a spacecraft into it. The target is Dimorphos, a moonlet orbiting the asteroid Didimus. The mission will help determine the momentum needed to deflect an asteroid. Additionally, the video explores a unique planetary system where planets orbit perpendicularly, challenging conventional understanding of planetary formation. Researchers suspect a large body, possibly a brown dwarf, influences these orbits, highlighting the complexity of space systems.

What is the primary objective of NASA's DART mission?

• To establish a human base on an asteroid

• To test the ability to redirect an asteroid's path

• To explore the surface of an asteroid

• To collect samples from an asteroid

Which celestial body is the target of the DART mission?

• The star HD3167

• The planet Mars

• The moonlet Dimorphos

• The asteroid Didimus

What is the expected change in Dimorphos's orbit after the DART impact?

• It will stop orbiting Didimus

• It will orbit 10 minutes faster

• It will be ejected from its orbit

• It will orbit 10 minutes slower

What is unusual about the planetary system orbiting the star HD3167?

• The planets are all the same size

• The planets have perpendicular orbits

• The planets orbit in a perfect circle

• The planets are all gas giants

What might be causing the unusual orbits in the HD3167 system?

• A supernova explosion

• A large planet or brown dwarf

• A comet passing through the system

• A nearby black hole
