An asteroid over 1,000 feet will pass by Earth this weekend, and while it's not expected to hit our planet, it is estimated to be worth nearly $5 billion.
Asteroid May Be a Chip off the Old Moon - Eos
Near-Earth objects are fragments of rock that orbit the Sun along paths that remain close to Earth. Researchers study these objects to assess their threat level but also to improve our understanding of the solar system.
A team of researchers at the University of Arizona have evaluated spectral data collected over several years and have determined that Kamo'oalewa may actually be a fragment of the Moon. The results of the study were published last month in Nature Communications Earth and Environment .
Asteroid that wiped out the dinosaurs hit Earth during northern spring, scientists argue | Space
The asteroid impact that wiped out most dinosaurs may have taken place during the Northern Hemisphere's spring or early summer, according to new research on the infamous mass extinction.
The new research hinges on a site called Tanis, located in North Dakota, that an overlapping group of scientists announced in 2019.
NASA to test solar-powered propulsion for asteroid defense – pv magazine USA
The Double Asteroid Redirection Test (DART) mission will employ roll-out solar arrays and an electric propulsion system to redirect Earthbound asteroids.
NASA's Double Asteroid Redirection Test (DART) mission launched to test the use of solar-powered electric propulsion to protect Earth from incoming asteroids.
This huge asteroid, set to fly past earth, is worth $5 billion in metals, Science News |
Nereus asteroid: According to NASA, the asteroid will be roughly 2.4 million miles away from Earth on Saturday, the closest it will be until 2060, when it will be only 744,576 miles away. Photograph:( Twitter )
The asteroid, which EarthSky claims travels at 14,719 mph, circles the sun every 664 days and passes reasonably close to Earth roughly once every decade.
Scientists plan to land on Apophis, an ominous asteroid set for a rare Earth flyby - CNET
Artwork of an asteroid approaching Earth. In 2029, Apophis will fly lower than many artificial satellites.
Still, scientists see a rare opportunity to study such a large body and also conduct a planetary defense exercise that will be as close to the real thing as humanity has ever seen.
How was the asteroid belt formed?
How was the asteroid belt formed? I heard there was supposed to have been another planet there, but there doesn't seem to be enough material there for a planet…
This is an awesome question, Jessie. To answer it, we have to board a time-travelling spaceship and head back to the birth of the solar system itself.

Science advisor Amy Mainzer talks asteroids and new Netflix movie "Don't Look Up" | Space
Asteroid scientist Amy Mainzer found herself in a unique position these past few months: chatting with Leonardo DiCaprio about science and asteroids.
An official trailer for "Don't Look Up" from September showed DiCaprio (who plays astronomer Randall Mindy) and Jennifer Lawrence (who plays astronomer Kate Dibiasky) trying to convince fictional White House officials that there's a giant comet headed straight for Earth.
How Did Crocodiles Survive the Asteroid That Wiped Out the Dinosaurs?
About 66 million years ago , dinosaurs ruled Earth. But then a massive asteroid, more than 9 kilometers wide, slammed into the shallow sea near what is now Mexico.
The explosion from this was so huge, it led to global earthquakes, tidal waves, bushfires, and even poisonous rain.
