    The European Southern Observatory (ESO) and ESA (European space agency) teamed up to produce a packed Asteroid Day webcast. There were interviews with ESA and ESO scientists. Updates from Europe’s asteroid hunters and some of the most recent asteroid science results, including the blockbuster news on Oumuamua, the first-ever interplanetary visitor. The programme also included an interview with ESA astronaut Luca Parmitano on the challenges of future human missions to asteroids, as well as a surprise segment that answered the age-old question: What really killed off the dinosaurs? More than 1M asteroids have the potential to impact Earth and through...
  • What’ll happen when 3200 Phaethon sweeps past Earth?

    3200 Phaethon was the first asteroid to be discovered via spacecraft on October 11, 1983. Astronomers Simon F. Green and John K. Davies noticed it while searching Infrared Astronomical Satellite (IRAS) data for moving objects. Charles T. Kowal confirmed it optically and said it was asteroid-like in appearance. The object received the provisional designation 1983 TB. Two years later, in 1985, using the convention for naming asteroids, astronomers assigned it its number and name: 3200 Phaethon. An interesting feature of the orbit of 3200 Phaethon is that it comes very close to the sun, closer than any other named asteroid...
  • Asteroid Warning: Fragments which could wipe out Nations 'hidden in Taurids meteor shower'

    The startling finding means that experts may not be able to spot the massive space rock hidden in the annual Taurids meteor shower until it is too late. According to a group of researchers, one of the fragments could hit Earth in 2022, 2025, 2032 or 2039 during the annual meteor shower. The Taurids is a spectacular meteor shower that lights up the night skies every November. The meteor shower is the trail of debris left by the comet Encke. But the debris could be obscuring two asteroid chunks known as 2015 TX24 and 2005 UR that are potentially Earth-bound....
  • Impact of asteroid that will approach Earth in 2029 'CANNOT be ruled out' [but pretty much no]

    Astronomers have calculated the Apophis asteroid will speed past Earth on April 13, 2029, at just 18,600 miles away -- a hair's width in astronomical terms. To put that into perspective, the moon is 238,900 miles away... If the 27 billion kg asteroid were to hit Earth, scientists calculate that it would leave a crater over a mile wide and a staggering 518 metres deep. However, most worryingly, the impact would be equivalent to 880 million tons of TNT being detonated -- some 65,000 times as powerful as the nuclear bomb which was dropped on Hiroshima. The next time the...

    An artist's impression of how the proposed asteroid-suspended Analemma Tower would look. The building will be suspended from an asteroid orbiting 50,000kms from the earth A New York-based firm is proposing that Dubai be the site of a futuristic, asteroid-suspended skyscraper that orbits around the world. The speculative Analemma Tower - which is being proposed by the Clouds Architecture Office - is designed to be suspended downward on an asteroid orbiting 50,000km from earth. It would orbit in a figure-eight pattern across the northern and southern hemispheres in a 24-hour cycle each day. A design close-up of the asteroid from...

    The space rock is coming for a visit, but it won't get too close for comfort. T he 4 Vesta asteroid is currently making a drive-by visit to Earth. The asteroid, which reportedly measures more than 300 miles in diameter, is now so close to Earth that at night, you can see it with your very own eyes — no telescope required. ... So why isn’t anyone freaking out over this massive rock flying through space so close to Earth? Because even though it’s so close we can see it in the night sky, it’s not actually that close at...

    The Japan Aerospace Exploration Agency (JAXA) released several new images that Hayabusa2 snapped recently of the asteroid Ryugu, whose shape has now become clear. "From a distance, Ryugu initially appeared round, then gradually turned into a square before becoming a beautiful shape similar to fluorite (known as the 'firefly stone' in Japanese)," Hayabusa2 project manager Yuichi Tsuda wrote today (June 25) in a description of the newest photos, which the probe took Saturday and Sunday (June 23 and 24), from as close as 25 miles (40 kilometers). "Now, craters are visible, rocks are visible and the geographical features are seen...

    The world’s first trillionaire won’t come from cryptocurrency or some clever new app – he or she will become rich from asteroid mining. _____________________________________________________________________ That’s what bankers Goldman Sachs reckon, anyway – and several companies are now vying to be the first into space. NASA estimates that the total value of asteroids out there could be up to $700 quintillion – equivalent to £75 billion each for us here on Earth. Several companies are now buidling the machines which will take us there – including Deep Space Industries, which is building a steam-powered thruster for spacecraft, the Guardian reports. British...

    A boulder-sized asteroid designated 2018 LA was discovered Saturday morning, June 2, and was determined to be on a collision course with Earth, with impact just hours away. Because it was very faint, the asteroid was estimated to be only about 6 feet (2 meters) across, which is small enough that it was expected to safely disintegrate in Earth's atmosphere. Saturday's asteroid was first discovered by the NASA-funded Catalina Sky Survey, located near Tucson and operated by the University of Arizona. Although there was not enough tracking data to make precise predictions ahead of time, a swath of possible locations...

    https://www.minorplanetcenter.net/db_search/show_object?object_id=2018+GE3 http://spaceweather.com/ SURPRISE ASTEROID FLYBY: With little warning, a relatively large asteroid flew through the Earth-Moon system on April 15th only 192,200 km (0.5 LD) from our planet. 2018 GE3 was discovered by the Catalina Sky Survey approaching Earth on April 14th. Hours later, amateur astronomer Michael Jäger of Weißenkirchen Austria video-recorded the space rock rushing through the southern constellation Serpens: "According to wikipedia, 2018 GE3 is the largest known asteroid to pass that close to Earth in observational history," says Jäger. "It was shining like a 13th magnitude star at the time of my observations." Based on the intensity of its reflected...

    Universe Today ^ | 3/13/18 | Evan Gough
    Some might say it’s paranoid to think about an asteroid hitting Earth and wiping us out. But the history of life on Earth shows at least 5 major extinctions. And at least one of them, about 65 million years ago, was caused by an asteroid. Preparing for an asteroid strike, or rather preparing to prevent one, is rational thinking at its finest. Especially now that we can see all the Near Earth Asteroids (NEAs) out there. The chances of any single asteroid striking Earth may be small, but collectively, with over 15,000 NEAs catalogued by NASA, it may be only...
  • 1st Known Interstellar Visitor Gets Weirder: 'Oumuamua Likely Had 2 Stars

    Our solar system's first known interstellar visitor is likely even more alien than previously imagined, a new study suggests. The mysterious, needle-shaped object 'Oumuamua, which was spotted zooming through Earth's neighborhood last October, probably originated in a two-star system, according to the study. 'Oumuamua means "scout" in Hawaiian; the object was discovered by researchers using the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS), at Haleakala Observatory on the island of Maui. ... "It's really odd that the first object we would see from outside our system would be an asteroid, because a comet would be a lot easier to...
  • 2017 VR12: Asteroid That Could Be Bigger Than Empire State Building Is About to Pass by Earth

    newspeak ^ | 3/2/18 at 7:14 | Katherine Hignett On
    An asteroid up to 1600ft in diameter is set to fly by Earth in the early hours of March 7. Named “2017 VR12”, NASA has called the object “potentially hazardous.” But don’t worry—the space rock shouldn’t get closer than 900,000 miles from Earth. That’s far enough to stay safe, and maybe even close enough to watch on a home telescope. Larger than the Empire State Building? It is difficult to work out an asteroid’s size at great distance, but we can estimate. “The asteroid is a mere point of light in our telescopes: we cannot resolve its size that way,” Paul...
  • Two Asteroids Make Close Flybys of Earth

    02/08/2018 9:39:35 AM PST · by BenLurkin · 14 replies
    The two asteroids are called 2018 CB and 2018 CC, and they were both discovered February 4 through an automated telescope search called the Catalina Sky Survey, according to NASA's Minor Planet Center. The Catalina telescopes belong to just one of many observatories worldwide that regularly scan the sky to track and search for space rocks, also known as asteroids. While the majority of asteroids in Earth's solar system orbit in the asteroid belt between Mars and Jupiter, asteroid flybys of Earth happen several times a year. The last known close asteroid flyby was on Sunday (Feb. 4). The flybys...

    AN ASTEROID will hurtle towards Earth today – just one week after another dangerously close encounter. The newly-discovered space rock – named Asteroid 2017 TD6 – is expected to zoom past our planet at around at around 7.53pm. It will be travelling at a distance of 191,000km away from civilisation. According to NASA the chunk of rock is a whopping 22m wide. Last week another asteroid made a close shave with Earth, as it soared past at a distance of just 27,000 miles above the surface. And experts have warned a second bus-sized asteroid will zoom past our planet again...

    After several months of downtime after Hurricane Maria blew through, the Arecibo Observatory Planetary Radar has returned to normal operation, providing the highest-resolution images to date of near-Earth asteroid 3200 Phaethon during its Dec. 16 flyby of Earth. The radar images, which are subtle at the available resolution, reveal the asteroid is spheroidal in shape and has a large concavity at least several hundred meters in extent near the leading edge, and a conspicuous dark, circular feature near one of the poles. Arecibo's radar images of Phaethon have resolutions as fine as about 250 feet (75 meters) per pixel.
