“This is the largest space rock we have identified that will come this close until 2028.”

“YU55 poses no threat of an Earth collision over, at the very least, the next 100 years,” he said. “During its closest approach, its gravitational effect on the Earth will be so miniscule as to be immeasurable. It will not affect the tides or anything else.” 

“So stay tuned. This is going to be fun.” - Don Yeomans, manager of NASA’s Near-Earth Object Program.

“While near-Earth objects of this size have flown within a lunar distance in the past, we did not have the foreknowledge and technology to take advantage of the opportunity,”

“This is a C-type asteroid, and those are thought to be representative of the primordial materials from which our solar system was formed,”

This flyby will be an excellent opportunity to test how we study, document and quantify which asteroids would be most appropriate for a future human mission.” - Barbara Wilson, a scientist at JPL.
