The most detailed telescope photographs yet of the asteroid Kleopatra — named after the ancient Egyptian queen — clearly show its weird "dog-bone" shape, and astronomers say their studies of it could yield clues about the solar system.
The latest observations of the asteroid, more than 125 million miles from Earth in the main asteroid belt between Mars and Jupiter, have allowed scientists to more accurately measure Kleopatra's unusual shape and mass — and it's turned out to be about a third lighter than expected, which gives
NASA Upped the Chance of Asteroid Bennu Slamming Into Earth – Putting the Odds in Perspective
Using NASA’s Deep Space Network and state-of-the-art computer models, scientists were able to significantly shrink uncertainties in Bennu’s orbit, determining its total impact probability through the year 2300 is about 1 in 1,750 (or 0.057%).
Two statisticians put into perspective the chances of asteroid Bennu striking Earth in the next 300 years.
Asteroid that wiped out dinosaurs shaped fortunes of snakes - BBC News
Snakes owe their success in part to the asteroid strike that wiped out the dinosaurs, according to a new study.
But scientists say a handful of surviving snake species were able to thrive in a post-apocalyptic world by hiding underground and going long periods without food.
EarthSky | Dog-bone asteroid Kleopatra makes a fetching portrait
216 Kleopatra – aka the dog-bone asteroid – might paws-ibly be the cutest object in the asteroid belt between Mars and Jupiter. It was one of the earliest asteroids to be discovered, in 1880.
The European Southern Observatory released the images this week (September 9, 2021) and said the new observations caused astronomers to realize this fetching asteroid is a little ruff around the edges.
Nasa will crash a spacecraft into this asteroid to slow it down by 1% - SCIENCE News
Remember the Bruce Willis starred Armageddon, where a group of rag-tag amateur astronauts launched on a mission to deflect an asteroid headed towards Earth? Nasa is now in the final stages of attempting a similar mission, but not with astronauts.
The DART mission will target an asteroid as engineers and astronomers aim to create a defence system able to deflect potential asteroids headed towards Earth in future.
Observatory in Chile captures highest-resolution measurements of asteroid surface temperatures |
Researchers at the California Institute of Technology participating in a program supported by the U.S. National Science Foundation examined millimeter-wavelength light emissions from the asteroid Psyche to learn more about its origin and surface.
Psyche orbits the sun in the Asteroid Belt, a round and hollow region of the Milky Way that is home to more than a million cosmic entities ranging in size from small to enormous.
Asteroid Pallas Makes a Point in Pisces - Sky & Telescope - Sky
Spice up your fall observing with a dash of Pallas and nibble of Neptune. Both planet and asteroid are easy to spot in a small telescope.
I've never been able to wrap my mind around the fact that the total mass of the main asteroid belt equals just 4% the mass of the Moon. That seems hardly enough to matter, and yet our fate rests on those scraps and shards.
NASA To Slam Into Asteriod To Test Earth Defense - Are We Safe?
NASA will crash a spacecraft into an asteroid in an attempt to alter its trajectory and test the feasibility of asteroid redirection missions that could save Earth in the future. The mission is known as DART and will launch this November.
The target of NASA's mission is the asteroid Didymos, a binary system consisting of an asteroid and a small moonlet.
This Asteroid is a $10,000-Quadrillion Lump of Iron and a Potential Opportunity to Study an
Out between Mars and Jupiter in the solar system’s asteroid belt, there’s a lump of iron and nickel called 16 Psyche that has a value of $10,000 quadrillion: that’s 70,000-times more than the entire world economy.
With measurements of its density paired with its 140 mile-diameter, recent telescopic surveys with different spectrums of UV light have confirmed the asteroid to be around 90% iron, adding the last value in the equation to give 16 Psyche its whopping price tag .
