The Solar System Might Have a New Dwarf Planet! SciShow News

The video discusses the potential reclassification of Hygieia as a dwarf planet, highlighting its spherical shape and unique origin story. It also covers the observation of neutron star collisions, which produce heavy elements like strontium, providing insights into the universe's composition and confirming the neutron-rich nature of neutron stars.

What are the criteria for an object to be classified as a dwarf planet?

• It must orbit the Sun, be spherical, and clear its orbit.

• It must orbit the Sun, be spherical, and not clear its orbit.

• It must orbit the Sun, be irregularly shaped, and clear its orbit.

• It must orbit the Sun, be irregularly shaped, and not clear its orbit.

What was the unexpected finding about Hygieia's surface?

• It has numerous large craters.

• It lacks large craters.

• It is made of metal.

• It is covered in ice.

What hypothesis explains the lack of large craters on Hygieia?

• Hygieia was protected by a magnetic field.

• Hygieia was never part of a larger body.

• The parent body was destroyed, and Hygieia reformed from the debris.

• Hygieia was formed from volcanic activity.

What significant event was observed in 2017 involving neutron stars?

• The formation of a new neutron star.

• The disappearance of a neutron star.

• The collision of two neutron stars.

• The explosion of a neutron star.

What process is responsible for creating heavy elements during neutron star collisions?

• Radioactive decay

• Electromagnetic radiation

• Rapid neutron capture

• Nuclear fusion
