On September 26, the Double Asteroid Redirection Test (DART) spacecraft is due to crash into the side of Dimorphos, a small asteroid orbiting the larger near-Earth asteroid Didymos, at a speed of ...

The asteroid in question, a 525-foot-wide body known as Dimorphos, is actually a moon orbiting a 2,500-foot-wide asteroid named Didymos. Neither poses any threat to Earth, either before or after ...

Primarily, an analysis of the craters and surface strength on Didymos indicated it formed about 12.5 million years ago, while its smaller companion, Dimorphos, formed about 300,000 years ago.

It spotted Didymos earlier this summer ... $250 million spacecraft In addition to the observatories in space and on Earth that will be watching, DART’s own camera will be sending back images ...

Asteroids colliding with Earth might seem farfetched, but the planetary threat is real. Just this year news broke of an ...

This animation shows how Dimorphos’ orbit around Didymos was seen from Earth about one week after the DART impact. Based on limited data about how Dimorphos now spins after DART struck it ...

If DART hits Dimorphos at 15,000 mph as planned, it will test the kinetic impactor Earth defense theory. The double asteroid system features the larger Didymos and DART’s target Dimorphos.

2500-foot-wide asteroid Didymos was never a threat to Earth, and neither was poor little Dimorphos, the 500-foot-wide clump of rocky debris that orbits Didymos.
