In less than two years, the New Horizons space probe is going to go whizzing by an object a billion miles further away from us than Pluto at speeds of up to 30,000 miles per hour. We know generally where that object—MU69, a cold dark object in the Kuiper Belt—will be thanks to telescope observations, otherwise we wouldn't be able to rendezvous with it at all, but like a blind date, we're not 100 percent sure what to expect. Details like the shape, exact size, color of the object and even if it has close neighbors all remain elusive.
Last month, NASA researchers got a tantalizing glimpse of their next big destination when it passed between telescopes on Earth and the light of a distant star. But it has taken time to resolve that data into clues.
Now, NASA has released two new illustrations of what MU69 might look like based on that data. They think that overall the object is likely about 20 miles long, but its observed shape raises even more...
