Asteroid 2003 SQ222
vir: The Queen's University BelfastKot poročajo New Scientist, je prejšnji vikend letel mimo Zemlje asteroid, ki se ji je izmed vseh opazovanih najbolj približal, saj je letel le 88.000 km mimo nas. Spomnimo, da geostacionarni sateliti krožijo na oddaljenosti približno 39.500 km. Asteroid so poimenovali 2003 SQ222, njegov obhodni čas okrog Sonca po zelo eliptični tirnici pa znaša 1,85 zemeljskega leta.
Novico so objavili tudi pri Washington Times, kjer pa so jo prekomerno napihnili, trdeč, da je šlo za vesoljsko telo srednje velikosti. V resnici je SQ222 eden izmed najmanjših zaznanih asteroidov, ki so potovali mimo Zemlje (in delno skozi njeno eksosfero). Izmerili so mu velikost 3 - 5 metrov, medtem ko je...
"We use chemistry to maintain near-complete control over the physical properties of the nanotube. You can introduce functional molecules at any position along the outside of the nanotube to control its physical properties with chemistry. For instance, if you want something that is photo-active — that absorbs photons and transports them to a new location in the assembly — then you can introduce components in the parent molecule that absorb light. If you want it to conduct electricity, then you introduce a component into the parent that absorbs an electron and transfers it from one rosette to the next," said Fenniri.
