The sun’s light exerts a tiny force called “solar radiation pressure” on objects in space. Lightweight human-made debris, like hollow rocket parts, gets pushed around more easily, like a tin can in the wind. Natural objects like asteroids are much denser and less affected.

Alinda, measuring 2.6 miles wide, will be visible this weekend. Stargazers can spot it using basic equipment or watch a livestream. Events like this occur once in a decade.

Further simulations on flybys into the inner Solar System revealed one of our own planets might be flung out of the ballpark within the following 20 million years or so in just 2 percent of cases. In all others, the inner planets remained in slightly altered but still relatively harmonious orbits.

Typically, asteroids - like the one depicted in this artist's concept - originate from the main asteroid belt between the orbits of Mars

The asteroid is estimated to be between 656 and 1,443 feet across, and will pass at 16 times the distance to the moon.

The Alinda asteroid will be visible with binoculars in a 'once in a decade' event as it brushes past Earth, with its return to the planet not expected until 2087

"it's not completely unusual for asteroids to be near the Earth," Gallagher said. "Our moon is about a quarter million miles away from the Earth. So something 7.6 million miles out would be many, many, many times father away from the Earth than the moon is. No cause for alarm."

A meteorite crash-landed on his home’s walkway. Hoping to confirm what he saw on his camera, Velaidum sent his home security video and pictures to Chris Herd, an expert in meteorites at the University of Alberta. Herd confirmed that it was indeed a meteorite and that it was a history-making moment.

Astronomer Dean Regas gives us the lowdown on the best things to look out for this winter, from a “planet parade” to the ATLAS comet.

Emily Simpson has loved space since she was a 10-year-old kid celebrating her birthday at a planetarium. Now a recent Florida Tech graduate, she leaves with not only a dual degree in planetary science and astronomy and astrophysics but with published research,

The asteroid was first discovered last year on August 7, 2024. To rule out 2024 PT5 being space junk, scientists at NASA’s Center for Near Earth Object Studies (CNEOS) analysed its motion but the the effects were found to be too small for the object to be artificial, proving 2024 PT5 is most likely of natural origin.
