Scientists suggest an interstellar visitor may have altered planetary orbits in our Solar System, reshaping trajectories of Jupiter, Saturn, Uranus, and Neptune.

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.

Alinda is one of the five largest near-Earth asteroids, coming closer than 9.3 million miles until the year 2200.

Doorbell cameras aren’t just for busting home invaders and porch pirates. A Ring camera captured the sound of a meteorite crash-landing near a house in Prince Edward Island, Canada, marking the first time this interstellar noise had been recorded alongside video footage.

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.

This is the first time the sound of a meteorite hitting Earth has been recorded, the University of Alberta said.

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."

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,

Chiron is a class of comet-ish asteroids/asteroid-ish comets called centaurs – named after the half-human, half-horse hybrid – found bouncing between Jupiter and Neptune. But Chiron is an ‘oddball when compared to the majority of other centaurs,’ said physicist Charles Schambeau of the University of Central Florida.

Sometimes, it's easy to forget that we're spoiled with one of the best observatories in our solar system, and it's called Earth. In fact, this Tuesday (21 January), six planets will line up in the night sky above us, for all to see.
