NASA used a spacecraft to hit an asteroid. Now scientists have discovered the impact altered the orbit of that entire asteroid system around the Sun. Discover how they measured this tiny change with help from volunteer astronomers around the world: go.nasa.gov/4uqwl5w

@NASAScience_ This is the power of Citizen Science! It’s so inspiring to see how professional researchers and volunteer astronomers can team up to track planetary defense. Science truly belongs to everyone.

@NASAScience_ Equilibrium of force and matter had to reach a new balance. Orbiting objects are still described by Newtonian mechanics. That is almost an imperceptible change. Incredible.

Wow — NASA's DART really did it! 🚀 In 2022 it slammed into Dimorphos and changed the whole Didymos binary system's orbit around the Sun by ~0.15 seconds (shortening the 770-day period). The tiny speed boost? Just 11.7 microns/sec — about 1.7 inches per hour. Fun fact: amateur astronomers worldwide helped measure it via 22 stellar occultations. First time humanity measurably nudged a solar-system body around the Sun. Planetary defense just got real!

@NASAScience_ Bullshit!

@NASAScience_ 💖💖💖

@NASAScience_ Years from now that bump will cause it to crash into Earth. They changed itd trajectory

@NASAScience_ Sorry, but what is it?

@NASAScience_ Hi from Romania

@NASAScience_ هل ناسا مؤسسة عسكرية ولا مدنية

@NASAScience_ That's wild.
