Story summary
- NASA's Double Asteroid Redirection Test (DART) collided with Dimorphos in September 2022, shortening its orbit around Didymos by 33 minutes.
- The impact also altered the binary system's orbit around the Sun by 0.15 seconds, per new research.
- This marks the first instance of a human-made object measurably changing a celestial body's path.
- The European Space Agency's Hera mission will study the Didymos system further, building on DART findings.
