New research on the orbits of these mysterious asteroids near Venus stress the need for better space rock surveillance.

Astronomers are making a surprising breakthrough in the study of Venus, as new simulations suggest there may be a hidden ...

Only one of the known Venus co-orbital asteroids follows a nearly circular orbit; the others move on more elongated paths ...

A swarm of large asteroids likely lurking around Venus could one day pose an "invisible threat" to Earth if left unchecked, ...

One summer night in 1877, American astronomer Asaph Hall was looking through his telescope in Washington, D.C. Mars was at ...

The Vera C. Rubin Observatory is expected to find millions of unknown objects in our solar system, and perhaps even a ...

Of these ‘six invisible threats’, three named 2020 SB, 524522, and 2020 CL1 ‘have a severe risk of collision’ as their orbits allow them to approach Earth within 0.05 astronomical units ...

ESA image showing the 156 823 asteroid orbits detected by Gaia. The wider blue and yellow circles in the frame show planetary orbits, while the myriad colorful inner swirls are asteroids.

This asteroid might not hit Earth in 2032 after all—here’s how we know. Space agencies have systems in place to spot, track, and forecast the future orbits of potentially hazardous asteroids.

NASA is monitoring three asteroids soaring past the Earth at about 8,000 to 15,000 miles per hour, the biggest of which ...

However, the powers that be better hurry, as researchers predict that co-orbital asteroids’ orbits could become unpredictable in just more than 150 years — a blip in the interstellar timescale.

When NASA scientists recently tracked the orbits of two space rocks as they made close approaches of Earth, they discovered a surprise: One of the asteroids has a little moon.. Astronomers ...
