‘Puin’-asteroïden zijn verrassend lastig te vernietigen

Een onderzoeksteam denkt dat zogenaamde puin-asteroïden lastig zijn te vernietigen en dat ze zeer algemeen in ons zonnestelsel voorkomen.

The study’s results showed #asteroid #Itokawa, which is 2 million kilometers from Earth and around the size of Sydney Harbour Bridge, was hard to destroy and resistant to collision.

#GaurkoEgunez 2005. urtean, JAXAko #Hayabusa espazio-zunda #Itokawa asteroidean lurreratu zen eta asteroidearen material-ale ñimiñoak jasotzen zituen. Zunda 2003an jaurti zuten eta 2010ean itzuli zen Lurrara jasotako materialarekin.

"The samples from asteroid 25143 Itokawa include not only ordinary chondrite material but also cubanite, a copper-iron-sulfide rare in the meteorite record and likely formed on a different parent body"
