  • 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.
  • Giant 'Potentially Hazardous' Asteroid Will Whiz By Earth So Close We Can See Inside It

    On February 4, an asteroid called 2002 AJ129 is due to slip past Earth. It is between 1600 and 4000 feet across, according to NASA's Center for Near Earth Object Studies, but there's no chance it will make impact—NASA has calculated it will remain 2.6 million miles away. That still makes it what astronomers call a "potentially hazardous asteroid," thanks to its size being more than about 500 feet across and an orbital path that carries it within about 4,650,000 miles of Earth. But while they're confident we won't all go the way of the dinosaurs, scientists do want to keep an eye on the...
  • How California’s Plan to Protect Undocumented Immigrants Will Play Out in San Diego

    Voice of San Diego ^ | Tuesday, January 2, 2018 | Maya Srikrishnan
    California offers some of the broadest protections and rights to undocumented immigrants in the country, and the California Values Act, which went into effect Jan. 1, makes those protections even stronger. Indeed, the law – also known as SB 54, or the sanctuary state law – will have a significant impact, particularly for certain people. It will also eventually shed light on the way local law enforcement interacts with federal agencies, like Border Patrol, the FBI and Immigration and Customs Enforcement. But particularly in San Diego County, where there are high concentrations of federal law enforcement and numerous joint local...

    A MASSIVE asteroid that could have destroyed New York City skimmed past Earth – and NASA had no clue. The large space rock – dubbed 2017 VL2 – passed the planet on November 9 at an astonishing distance of just 73,000 miles, which is considered tiny in space terms. Space boffins think that if the rock measuring between 16 and 32 metres had hit, it could’ve wiped a major city such as New York off the map. The rock belongs to the Apollo group of asteroids and was first seen at ATLAS-MLO observatory in Hawaii a day later. It was...

    A gigantic space rock called 3200 Phaethon is due to brush ‘quite close’ to our planet on December 17, Russian astronomers have revealed. This huge asteroid is thought to cause the beautiful Geminids meteor shower which will take place between December 13 and 14, causing hundreds of bright meteors to illuminate the night sky as they burn up in Earth’s atmosphere. But NASA has also described it as a ‘potentially hazardous asteroid whose path misses Earth’s orbit by only 2 million miles‘ – which is tiny in galactic terms. It’s about half the size of Chicxulub, the rock which wiped...

    NASA ^ | 11/20/2017
    Now, new data reveal the interstellar interloper to be a rocky, cigar-shaped object with a somewhat reddish hue. The asteroid, named ‘Oumuamua by its discoverers, is up to one-quarter mile (400 meters) long and highly-elongated—perhaps 10 times as long as it is wide. That aspect ratio is greater than that of any asteroid or comet observed in our solar system to date. While its elongated shape is quite surprising, and unlike asteroids seen in our solar system, it may provide new clues into how other solar systems formed. The observations and analyses were funded in part by NASA and appear...
  • Dwarf Planet Ceres May Have Had a Global Ocean in Ancient Past

    Nestled in the asteroid belt, the dwarf planet Ceres contains water-rich materials that suggest it once boasted a global ocean in its distant past. Now, two new studies from NASA's Dawn mission may reveal traces of an ancient ocean in the crust, with remnants left behind in the muddy mantle beneath.  Scientists used the tug of gravity on NASA's Dawn spacecraft to track gravitational features across the dwarf planet Ceres. Combined with models of the evolution of the icy surfaces, these observations reveal an ocean mostly frozen into a strong but flexible crust, with a mud-rich inner layer that keeps...

    Scientists believe a massive object that could change our understanding of history is hidden beneath the Antarctic ice. The huge and mysterious “anomaly” is thought to be lurking beneath the frozen wastes of an area called Wilkes Land. The area is 151 miles across and has a minimum depth of about 2,700 feet. Some researchers believe it is the remains of a truly massive asteroid more than twice the size of the Chicxulub space rock that wiped out the dinosaurs. If this explanation is true, it could mean this killer asteroid caused the Permian-Triassic extinction event, which killed 96 percent...

    Asteroid 2012 TC4 doesn't have a very memorable name, but it might leave quite an impression years from now. The house-sized asteroid that just passed by Earth, almost as close as many satellites in orbit, will be back -- and a future visit might lead to it taking up permanent residency here. On Tuesday night/Wednesday morning, Asteroid 2012 TC4 safely passed by our planet at an altitude of 27,300 miles (44,000 kilometers), just a few thousand miles above the level of satellites in geosychronous orbit. That's nearly twice as close as when it passed us almost exactly five years ago,...

    A house-size asteroid will give Earth a near-miss on Thursday, giving experts a rare chance to rehearse for a real-life strike threat as it passes inside the moon’s orbit. Dubbed 2012 TC4, the space rock will shave past at an altitude of less than 44,000km (27,300 miles) – just above the 36,000km altitude at which hundreds of geosynchronous satellites orbit the Earth. That represents about an eighth of the distance between the Earth and the moon. Nasa’s Mike Kelley, who leads the exercise to spot, track and intimately probe the transient visitor, insisted there was “no danger. Not even for...

    phys.org ^ | October 10, 2017 | Tomasz Nowakowski,
    Asteroid 2012 TC4 was discovered on Oct. 4, 2012 by the Pan-STARRS observatory in Hawaii. Week later, it gave Earth a close shave when it passed the planet at the distance of 0.247 LD (lunar distance), or 58,900 miles (94,800 kilometers). Observations reveal that 2012 TC4 is an elongated and rapidly rotating object that has been known to make many close approaches to Earth in the past. The space rock orbits the sun approximately every 1.67 years at a distance of about 1.4 AU. Astronomers estimate that 2012 TC4 has a diameter between 26 to 85 feet (8 to 26...

    NASA will coordinate with observatories around the world to try and get an exact trajectory for the asteroid in the days leading up to the flyby.... "This is the perfect target for such an exercise because while we know the orbit of 2012 TC4 well enough to be absolutely certain it will not impact Earth, we haven't established its exact path just yet," says Paul Chodas, manager of NASA's Center for Near Earth Object Studies. This experiment will test how well NASA can determine the orbit of a newly detected asteroid that might pose a danger to us. If the...

    Radar images obtained between August 29 and September 1, when Florence came closest to Earth, reveal that the asteroid is about 2.8 miles (4.5 kilometers) in size, the US space agency said. It said the two moons were probably between 300-1,000 feet (100-300 meters) across. The inner moon takes approximately eight hours to revolve around Florence while the outer moon takes between 22 and 27 hours, NASA said. NASA said the radar images of Florence, which was discovered in 1981, were obtained by the Goldstone Deep Space Communications Complex in California.

    Asteroid Florence will pass by Earth on Sept. 1, 2017, at a distance of 4.4 million miles (7 million kilometers). Image Credit: NASA / JPL-Caltech A large rock will fly past Earth on Sept. 1, 2017, at a distance of 4.4 million miles (7 million kilometers). Asteroid 3122 Florence, named after modern nursing founder Florence Nightingale, is the largest object to make a close-encounter since NASA began tracking near-Earth objects (NEO) in the 1990s. “While many known asteroids have passed by closer to Earth than Florence will on Sept. 1, all of those were estimated to be smaller,” said Paul...
