A small asteroid roughly the size of a house slipped past Earth on the night of May 18, 2026, passing closer than the Moon and threading through a region of space occupied by some of the satellites that keep GPS systems and communications networks running.

The livestream will begin at 3:45 p.m. EDT on May 18, bringing near real time views of the asteroid from robotic telescopes in Italy, weather permitting.

Asteroid mining seems simple in theory. A spacecraft flies up to a giant rock in space, scoops out some material, and either processes it on site or returns it back to a huge central processing facility.

Plotting the optimal trajectory to visit multiple asteroids is a fiendishly difficult take on the Traveling Salesperson problem, but a new mathematical approach has succeeded in solving it.

A famously unlucky date is getting a cosmic twist. NASA says the asteroid Apophis will safely pass close to Earth on Friday, April 13, 2029, coming about 20,000 miles from the planet's surface. That is closer than many satellites in geosynchronous orbit,

Earth has a group of cosmic stalkers. Known as "co-orbitals," these small bits of rock have a 1:1 mean motion resonance with Earth. Basically, they take the exact same amount of time to orbit the sun as we do.

Don’t look up! But if you do, you might be able to see a bus-sized asteroid passing Earth. The newly discovered space rock is said to make a close call early next week, flying by Earth, but rather than panic,

A newly discovered meteor stream may be the smoking gun of an asteroid slowly disintegrating under the Sun’s intense heat. Scientists say these fiery streaks across the night sky could reveal hidden near-Earth asteroids that telescopes struggle to detect.
