Chasing ‘Oumuamua—unfortunately human technology isn’t up to the task - Blog - Asteroid Day
A little more than a month ago, an interstellar visitor now known as 'Oumuamua passed within 24 million kilometers of Earth. It is now moving rapidly away from the Sun at a velocity of approximately 26km/s. That is considerably faster than, say, the Voyager 1 spacecraft, which is hurtling beyond the Solar System at a velocity of 17km/s.
