New Dwarf Planet (Maybe) Discovered

The video discusses the discovery of a new object in the Kuiper Belt, named 2014 UZ 224, which may be a dwarf planet. It meets three of the four criteria for dwarf planet classification, but its size and shape are still uncertain. Additionally, a new study suggests there are 2 trillion galaxies in the universe, ten times more than previously estimated. This revision is due to the difficulty in detecting dim and distant galaxies, and the study used a mathematical model to account for these challenges.

What is the name of the object discovered in the Kuiper belt that might be a new dwarf planet?

• Pluto

• Planet 9

• Eris

• 2014 UZ 224

Which of the following is NOT a criterion for an object to be classified as a dwarf planet?

• Hasn't cleared its orbit

• Orbits another planet

• Orbits a star

• Is large enough to be spherical

According to a new study, how many galaxies might there be in the observable universe?

• 1 trillion

• 2 trillion

• 500 billion

• 200 billion

What is one reason why counting galaxies is challenging?

• Galaxies are too small

• Galaxies are too dim and far away

• Galaxies are too close

What did astronomers use to create a model of how the universe developed?

• Satellite data

• Deep field images

• Space probes
