• A video compares the sizes of different asteroids
  • Some asteroids are large enough to wipe out cities
  • Planet-killer asteroids could end all life on Earth

A new video shared on YouTube compared some of the biggest asteroids that could hit Earth. Some of the asteroids are so big that they could easily trigger total mass extinction events and cause Earth to fragment once they hit the planet.

The new video was uploaded on YouTube by Metal Ball Studios, a channel that provides 3D comparisons of various objects and items. In its latest video, the channel compared some of the most well-known asteroids.

The short clip began with relatively small asteroids with estimated diameters ranging from 4.1 to 30 meters. The smallest asteroid in this group, identified as 2008 TC3, is significantly bigger than a human. The other two asteroids, namely 2014 RC and 2004 FH are bigger than houses.

Depending on the impact velocity of these asteroids, there’s a big chance that they won’t cause impact events on Earth. Instead, they will most likely burn up in the atmosphere and cause powerful explosions in the sky.

Towering over these asteroids are the city-killers, or those that are capable of wiping out large populated areas due to their immense size. The smallest asteroid in this group is 99942 Apophis. With a diameter of 370 meters, this asteroid is significantly taller than the Eiffel Tower in France.

Dwarfing Apophis are the kilometer-sized asteroids 69230 Hermes, (29075) 1950 DA and 4769 Castalia. With an average diameter of 1 kilometer, these asteroids are capable of causing major impact events and wiping out large areas due to the energy from their explosions. In the video, the sizes of these asteroids are highlighted by comparing them to the skyscrapers of a city.

The video then showed the asteroids that are capable of causing mass extinctions on Earth. Starting from 433 Eros, the diameters of this type of asteroids ranges from 16 to 33 kilometers. Aside from covering entire cities with their size, these asteroids make the other potentially hazardous space rocks look like pebbles.

Unfortunately, these aren’t the biggest planet-killer asteroids in space. Dwarfing all other asteroids in the video are 2 Pallas, 4 Vesta and 1 Ceres. Pallas and Vesta, which are 512 and 525 kilometers wide respectively, are referred to as minor planets due to their size. Ceres, on the other hand, measures 939 kilometers across and is known as a dwarf planet. Aside from ending all life on Earth, these giants could cause Earth to fragment during a violent impact event.
