@elmurpheytv @UN All asteroids travel faster than a speeding bullet! The slowest ones may travel at only 4 or 5 miles per second, but the fastest ones are over 40 miles per second relative to Earth. #AsteroidDay — PolitiTweet.org

@Ascendor @AsteroidWatch @UN The largest known object in the Main Asteroid Belt is the dwarf planet Ceres, which is about 580 mi (940 km) in diameter. It can be seen with a small telescope along with many others between Mars and Jupiter. #AsteroidDay — PolitiTweet.org

@AntiSquid1 @UN The key to planetary defense is finding them first. We have the technology to find any hazardous asteroid years to decades - even centuries before they could impact which then would provide plenty of time to divert them from impacting Earth. #AsteroidDay — PolitiTweet.org

NASA @NASA

@EyuChyu @AsteroidWatch @UN The key is the minimum time, ideally years to decades, to give plenty of time to launch an asteroid deflection mission, which is why discovering and tracking asteroids is critical. #AsteroidDay — PolitiTweet.org

NASA @NASA

@Iwillnotfall @UN We're working to discover and track near-Earth asteroids so that there would be enough time to prepare - up to years to decades - should any pose an impact threat. #AsteroidDay — PolitiTweet.org

@alinaillmeeer1 @UN Asteroids tend to spend most of their time millions of miles from Earth. Even during brief close passes to Earth the closest are still thousands of miles away. #AsteroidDay — PolitiTweet.org

@_vedantpatel @UN Meteors are the flashes we see in the sky made from incoming objects. Pieces of asteroids that make it to the ground are called meteorites. #AsteroidDay — PolitiTweet.org

@Jaspartapsingh3 @UN Apophis will safely pass Earth on April 13, 2029 at about one tenth the distance to the Moon, or approximately 38,000 km. Studying that will help assess if it poses any future concern. #AsteroidDay — PolitiTweet.org

@spencergoldade @UN Deflecting an asteroid will no longer be sci-fi once our Double Asteroid Redirection Test (DART) mission completes its technology demonstration of asteroid kinetic impactor deflection in 2022! #AsteroidDay — PolitiTweet.org

@NotSolhi @UN Near-Earth asteroids come within 30 million miles of Earth’s orbit and travel at roughly 30 km/s in their orbits around the Sun. #AsteroidDay — PolitiTweet.org

@nitin_quiry @UN Every day is #AsteroidDay for our team! Asteroid search programs discover objects every single day, including today. — PolitiTweet.org

@Empath_Witch_RN @UN Unlikely, most asteroids are orbitally bound within the solar system. #AsteroidDay — PolitiTweet.org

NASA @NASA

@Prakash251998 @UN This depends on the exact size of the asteroid and the amount of warning time we have, which makes early detection very important! The sooner we find an asteroid, the more time we have to mitigate it. #AsteroidDay — PolitiTweet.org

@caseywhalen57 @UN Yes, some asteroids contain iron, nickel and possibly other metals including some platinum group metals. #AsteroidDay — PolitiTweet.org

@rohankumar___ @UN We're developing the Double Asteroid Redirection Test (DART) mission which will test the kinetic impactor deflection technique by impacting Dimorphos, the moon of asteroid Didymos, in 2022. #AsteroidDay — PolitiTweet.org

NASA @NASA

@rohankumar___ @UN The bigger asteroids are, the fewer there are and the easier they are to find. We're watching the skies to find and track as many as possible and calculate their orbits. #AsteroidDay — PolitiTweet.org

Today is international #AsteroidDay☄️! To mark this @UN day, experts from our #PlanetaryDefense Coordination Office & the Double Asteroid Redirection Test (DART) are here to answer questions about finding asteroids & mitigating risk. Reply to this tweet with your questions! https://t.co/Hymvkn2PzL — PolitiTweet.org

When an asteroid or comet comes close to Earth we call it a near-Earth object. But how close is close? How do we keep track of them? What can we do to mitigate our risk? ☄️ Here’s what you need to know about near-Earth objects this #AsteroidDay: https://t.co/mCjW3FSoz5 — PolitiTweet.org
