Size of Asteroids vs New York City

3D animator Alvaro Gracia Montoya of MetaBallStudios (previously) created a fascinating, if not terrifying, animation that visually compares the size of exceptional asteroids in our solar system to the tall buildings and soaring skyscrapers of New York City. If any of these hit the Earth it would be devastating.

    On Friday, a large asteroid roughly the size of the Eiffel Tower zipped past the Earth. The asteroid posed no hazard to the Earth on this flyby as it was more than 40 times as far away from Earth as the moon. However, on April 13, 2029, Apophis will get closer to the Earth than some of the highest-orbit satellites surrounding the planet.
    Scientists at the University of Hawaii detected a small Yarkovsky acceleration on the surface of the asteroid Apophis which could influence the asteroid’s path for its 2068 flyby.
    The Yarkovsky effect is when an asteroid or celestial body changes its orbit due to small push of heat, either from itself expelling gasses, or the gravitational push and shove from celestial bodies including the Sun and Earth.
    In this instance, the scientists discovered a small thermal reaction which could slightly alter Apophis’s course.

    During the week of April 26, members of NASA’s Planetary Defense Coordination Office (PDCO) will participate in a “tabletop exercise” to simulate an asteroid impact scenario. The exercise depicting this fictional event is being led by NASA’s Jet Propulsion Laboratory’s Center for Near Earth Object Studies (CNEOS), allowing NASA’s PDCO and other U.S. agencies and space science institutions, along with international space agencies and partners, to use the fictitious scenario to investigate how near-Earth object (NEO) observers, space agency officials, emergency managers, decision makers, and citizens might respond and work together to an actual impact prediction and simulate the evolving information that becomes available in the event an asteroid impact threat is discovered.
    The fictitious impact scenario will occur during the 7th IAA Planetary Defense Conference, hosted by the United Nations Office for Outer Space Affairs in cooperation with the European Space Agency
    These type of exercises are specifically identified as part of the National Near-Earth Object Preparedness Strategy and Action Plan developed over a three-year period and published by the White House in June 2018.

    An international team of researchers searched for pieces of a small asteroid tracked in space and then observed to impact Botswana on June 2, 2018. Guided by SETI Institute meteor astronomer Peter Jenniskens, they found 23 meteorites deep inside the Central Kalahari Game Reserve and now have published their findings online in the journal Meteoritics and Planetary Science.

    Early Earth was bombarded by series of city-sized asteroids
    “Earth’s early years were unimaginably violent in comparison to today. Scientists believe that Earth was struck by a significant number of large asteroids (greater than 10 km in diameter), and this would have had significant effect on the Earth’s near-surface chemistry and ability to support life.”

    A potentially dangerous asteroid called Bennu has a 1 in 1,750 chance of hitting Earth between now and the year 2300.
    That’s according to the most precise calculations of an asteroid’s trajectory ever made, and the odds are slightly worse than NASA previously thought.
