The Sun will someday destroy the asteroid belt before it dies

The video explains the sun's transition into the giant branch phase, where it will expand and increase its luminance. This energy will affect the asteroid belt, causing asteroids to spin faster and break apart due to the York Effect. Over billions of years, these asteroids will become small fragments. Eventually, the sun will collapse into a white dwarf, absorbing the asteroid debris and altering its spectra, which explains the presence of asteroid elements in many white dwarfs.

What significant changes occur to the sun during the giant branch phase?

• It remains the same size but changes color.

• It becomes a black hole.

• It grows larger and its radiation output increases.

• It shrinks and cools down.

How does the increased energy from the sun affect the asteroid belt?

• It causes the asteroids to stop moving.

• It makes the asteroids spin faster until they break apart.

• It pushes the asteroids out of the solar system.

• It causes the asteroids to merge into a planet.

What is the YORP effect in relation to asteroids?

• A chemical reaction that changes asteroid composition.

• A magnetic field that repels asteroids.

• A heat-induced spinning effect that can break apart asteroids.

• A gravitational pull that attracts asteroids to the sun.

What happens to the sun after it collapses into a white dwarf?

• It turns into a neutron star.

• It absorbs the fragmented asteroids, altering its spectra.

• It disappears completely.

• It becomes a supernova.

Why do many white dwarfs' spectra suggest the presence of asteroid elements?

• Because they emit light similar to asteroids.

• Because they are made entirely of asteroids.

• Because they have a magnetic field that attracts asteroids.

• Because they have absorbed and polluted by smashed asteroids.
