The asteroid belt, hanging out between Mars and Jupiter, is not like the cluttered debris field in "The Empire Strikes Back." It may contain millions of rocky and metal objects, but the distances separating them are vast, and collisions are rare.
That is what makes P/2016 G1 such an exciting object. Spotted zipping through the asteroid belt in early 2016, this object had a strange orbit and a tail of dust that resembled a comet. Through a careful analysis of telescopic imagery, scientists identified multiple showers of debris shooting up from its surface, the sort that could have only been produced by an impact.
And here's another article:
Asteroid warning: NASA track 2,000FT monster rock on Earth approach after Christmas | Science |
Asteroid CH59 is comparable in size to China’s Canton Tower and The Sears Tower in Chicago, US.
Any object this large could potentially level an entire continent if it struck the planet unannounced.
Because of this potential danger and the asteroid’s close approach to our planet, NASA has characterised it as both a Potentially Hazardous Asteroid (PHA) and Near-Earth Object (NEO).

The asteroid report reads: “Near-Earth Objects (NEOs) are asteroids and comets that come close to or pass across Earth’s orbit around the Sun.
Impact crater data analysis of Ryugu asteroid illuminates complicated geological history |

Analysis of the impact craters on Ryugu using the spacecraft Hayabusa 2's remote sensing image data has illuminated the geological history of the Near-Earth asteroid.
A research group led by Assistant Professor Naoyuki Hirata of the Department of Planetology at Kobe University's Graduate School of Science revealed 77 craters on Ryugu. Through analyzing the location patterns and characteristics of the craters, they determined that the asteroid's eastern and western hemispheres were formed at different periods of time.
NASA Asteroid Tracker: 2 NEOs To Approach Earth At Start Of December
NASA noted that December will be kicked off by visits from two moderately-sized asteroids. According to the space agency, these two asteroids follow a natural orbit that intersects Earth's path.
The first asteroid that will approach Earth has been identified by the Center for Near-Earth Object Studies (CNEOS) as 2019 WH2 . As indicated in CNEOS' database, this asteroid is currently traveling across space at an average speed of 23,000 miles per hour. It has an estimated diameter of about 79 feet.
Many things are taking place:
Will Europe Finally Get Its Asteroid-Deflection Mission Off the Ground? | Space
BERLIN — Scientists and public advocates are trying to rally support for a proposed European Space Agency (ESA) mission to the near-Earth asteroid Didymos.
As a companion to NASA's Double Asteroid Redirect Test (DART) spacecraft, ESA's Hera mission would gather data that might be used in a planet-saving mission if we ever need to knock a space rock off a deadly collision course with Earth.
"To design a deflection mission, we have to predict what's going to happen," Kai Wünnemann, who leads the Berlin Natural History Museum's department of impact and meteorite research, send in a news conference held at the museum on Nov. 15.
Asteroid warning: Millions of 'nuclear bomb-like' asteroids threaten Earth | Science | News |
While this number seems large, there are tens of millions of near Earth objects (NEOs) in the solar system alone which have yet to be found and have the potential to cause large scale destruction on our planet.
A statement from the Asteroid Day organisers, which includes Dr Holger Sierks, principal investigator Rosetta/OSIRIS and Dr Patrick Michel, AIDA/Hera principal investigator, read: “There are several tens of millions of NEOs larger than 10 meters in size that would have an energy larger than a small nuclear weapon if they entered the Earth’s atmosphere, and we have identified just 21,443, as of 5th November, 2019.
Ice fossils found in 4.6 billion-year-old meteorite reveal building blocks of our solar system |
A 4.6 billion-year-old meteorite landed in Algeria in 1990, the remnant of a larger asteroid born during the dawn of our solar system.
New analysis of the meteorite, called Acfer 049, has revealed ice fossils trapped inside, making it the first direct evidence of frozen water as a building block of early asteroids.
Given the meteorite’s age, it also preserves material that created our solar system, providing a unique look at our corner of the universe and how it formed. The new findings published this month in the journal Science Advances .
Asteroid news: Giant space rock could be reclassified as TINY PLANET in solar system shock |
What was thought to be an asteroid known as Hygiea was believed the be the fourth largest object in the asteroid belt, situated between Mars and Jupiter, behind asteroids Vesta, Pallas and dwarf planet Ceres. However, new research conducted by using the European Southern Observatory (ESO) has found that Hygiea could be a dwarf planet too – making it the smallest of its kind in our solar system with a diameter of just 430km, considerably less than the 556km between London and Glasgow.
