At some point in the future, Earth is going to end up in the crosshairs of an asteroid that's big enough to be a threat. Whether it's a 'planet-killer' or a 'city-killer', we need to know about these asteroids, and we need to have a plan ...
Howevertheir latest prediction is that Earth will be safe fromApophis for the next 100 years.The scientists used radar(雷达)to predictthe asteroid's orbit(轨道) around the sun. NASAscientist Marina Brozovic said, “We were able to getprecise(精确的)information about its distanceto an accuracy ...

Luckily, the NASA-funded Pan-STARRS 2 survey telescope on Maui had imaged the part of the sky where the small asteroid could have been visible a couple of hours before the ATLAS observations. Using the potential orbit Farnocchia had calculated, Pan-STARRS scientists Robert Weryk and Mark Hube...
OSIRIS-REx used its suite of instruments to transmit radio tracking signals and capture optical images of Bennu during its study of the asteroid that will help NASA scientists determine its precise position in the solar system and its exact orbital path. As Bennu has the potential for recurring ...

But besides better accuracy, the Bayesian technique offered something equally as critical: it could tell the scientists how certain it was about its prediction. "In places where the data weren't good enough to give a really accurate result, this model was better at knowing that it wasn't sur...
