Russian Meteor: Member of an Asteroid Gang?

On Feb. 15, when a 10,000 ton space rock slammed into the atmosphere over the city of Chelyabinsk, Russia, injuring over 1,500 people and causing millions of dollars in property damage, the world suddenly became aware that our planet lives in a cosmic shooting gallery. We had suffered a planetary flesh wound. Almost immediately after the event, the question on everyone’s mind was: When will the next asteroid hit?

I started a thread back then.

Here Are The 1400 Potentially Earth-Ending Asteroids Circling Our Planet

There are more than 1,400 potentially dangerous asteroids orbiting alongside the Earth, and any one of them is big enough to end humanity.

One will be heading our way. Hope we can deflect one?? Asteroids pose a greater risk than the sun.

Is it the ones we know about that are dangerous, or is the ones that we don't know about.

I heard somewhere that there are comets that have periods longer that the 200 years where we have reliable records. If one of these is heading our way we might at best have a few months to see it and act before it strikes.

I don't know how well known this video is, asteroid discovery from 1980 up to 2011. The red ones cross Earth's orbit.

Read the "about" text on the original video (up to 2010) for a good explanation.

There are *a lot* of asteroids out there.

Around the World in Four Days: NASA Tracks Chelyabinsk Meteor Plume

A meteor weighing 10,000 metric tons exploded 14 miles above Chelyabinsk, Russia, on Feb. 15, 2013. Unlike similar past events, this time scientists had the sensitive instruments on the Suomi NPP satellite to deliver unprecedented data and help them track and study the meteor plume for months.

Video included with link.

Interesting...Thanx for the link, Lynn!

It's a good thing this didn't happen 25 years ago. It might have triggered WWIII. Back then tracking wasn't as sophisticated as it is today and Moscow might have mistaken it for a US missile launch.

Julie, your welcome!

Bob, +1

I hate to be so gloomy about asteroids. NASA and WISE telescope, teamed up to go hunting. Asteroid-hunter. One jolt from the asteroid belt, we might be gone.


NASA WISE telescope gets new life as asteroid hunter

Maybe this is something that Kepler could be reprogrammed to do.

Divers working at a Russian lake have recovered a half-tonne chunk of the space rock that exploded over Chelyabinsk earlier this year.

The object plunged into Lake Chebarkul in central Russia on 15 February, leaving a 6m-wide hole in the ice.

New Asteroid rated one of two most dangerous

Don't think I'll be around 2032.

A freshly discovered asteroid, with the classy name 2013 TV135, has a slight chance of smashing into Earth on August 26, 2032 and ruining everyone's day in a very big way.

Looks like this asteroid will be downgraded.

Newly discovered asteroid 2013 TV135 made a close approach to Earth on Sept. 16, when it came within about 4.2 million miles (6.7 million kilometers). The asteroid is initially estimated to be about 1,300 feet (400 meters) in size and its orbit carries it as far out as about three quarters of the distance to Jupiter's orbit and as close to the sun as Earth's orbit. It was discovered on Oct. 8, 2013, by astronomers working at the Crimean Astrophysical Observatory in Ukraine. As of Oct. 14, asteroid 2013 TV135 is one of 10,332 near-Earth objects that have been discovered.

This diagram shows the orbit of asteroid 2013 TV135 (in blue), which has just a 1-in-63,000 chance of impacting Earth. Its risk to Earth will likely be further downgraded as scientists continue their investigations.

Scientists studying the dramatic Chelyabinsk meteor that screamed through Russian skies this year have both good and bad news to report. The good news: The February fireball’s damage wasn’t nearly as terrible as predicted. The bad news? Near-Earth object impacts could be about 10 times more common than we thought they were.

Let's hope Scientists, are wrong.

Also..

A team of NASA and international scientists for the first time have gathered a detailed understanding of the effects on Earth from a small asteroid impact.

The unprecedented data obtained as the result of the airburst of a meteoroid over the Russian city of Chelyabinsk on Feb. 15, 2013, has revolutionized scientists' understanding of this natural phenomenon.

NASA's Hubble Sees Asteroid Spouting Six Comet-Like Tails

Astronomers viewing our solar system's asteroid belt with NASA's Hubble Space Telescope have seen for the first time an asteroid with six comet-like tails of dust radiating from it like spokes on a wheel.

A large asteroid has been discovered zipping past Earth that astronomers say is dangerous and will return on August 26, 2032.
