NASA's Pioneer 10 spacecraft beams its last data transmission back to Earth. Pioneer 10 was NASA's first mission to the outer planets. It was the first spacecraft to fly through the asteroid belt, the first to visit Jupiter,

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.

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

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.

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

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.

"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."

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,

UCF researchers utilized the James Webb Space Telescope to uncover unique characteristics of (2060) Chiron, a distant "centaur" that exhibits traits of both a comet and an asteroid. These findings provide valuable insights into the origins of our Solar System.

Joe Velaidum and his partner, Laura Kelly, set out to walk their dog when their doorbell camera captured a meteorite striking their front walkway — where Velaidum had been standing moments before.
