NASA says asteroid will come by very close....
get some booze and hunker down
NASA announced today that an asteroid 150-feet in diameter will pass close, but safely, by the Earth on Feb. 15.
"Since regular sky surveys began in the 1990s, astronomers have never seen an object so big come so close to our planet," NASA said.
The small near-Earth asteroid – 2012 DA14 – will pass so close that it will pass inside the ring of geosynchronous weather and communications satellites.
"NASA's Near-Earth Object Program Office can accurately predict the asteroid's path with the observations obtained, and it is therefore known that there is no chance that the asteroid might be on a collision course with Earth," the agency said in a press release.
"Nevertheless," it wrote, "the flyby will provide a unique opportunity for researchers to study a near-Earth object up close."
Yeah, real close – check out the graphics above to see just how close.
The agency will hold a teleconference on Thursday to talk more about the asteroid's flyby.

Now, thats a little scary. Scientists have been warning for a while about how crowded the real estate in orbit has become. If something was to strike a satellite and cause it to break apart, the debris could collide with other satellites and cause a chain reaction. We could in a very short amount of time lose a huge chunk of the satellites we depend upon everyday.

Why would it not get sucked into the Earth's gravitational pull?

Same reason the Moon doesn't. It's too far away to have much effect. That's why we park satellites out there.

It will, R20. The Earth's gravitational effects are factored into the computed trajectory.
|by Anonymous||reply 22||02/05/2013|
But it is much bigger than the satellites...
|by Anonymous||reply 23||02/05/2013|
Gravity, for something that's moving through the solar system at high speed isn't like a vacuum cleaner, pulling everything near it in. The Earth will cause its trajectory to curve a little, but in whatever direction it's moving, the inertia acting to keep it moving in that direction is stronger than the pull of Earth's gravity.
|by Anonymous||reply 24||02/05/2013|
Of course, a satellite could hit it and knock the asteroid enough so it diverts it into a collision course. If so, I hope it hits Topeka.

Perhaps the insufferable thinks-he-knows-it-all VOTN should just stop digging. I know several lawyers and doctors with the same disease.
He should have stopped when he answered the perfectly reasonable question:
"Why would it not get sucked into the Earth's gravitational pull?"
with this bullshit answer:
"Same reason the Moon doesn't. It's too far away to have much effect. That's why we park satellites out there."
Anyone with minimal exposure to physics knows it's the mass and relative speed of the objects that determine if something is captured by gravity. The asteroid will not be pulled into Earth's orbit or pulled into a collision because it's moving too fast relative to the Earth, not because it's too far away.
And, dufus VOTN, the Moon IS caught in our gravitational well. That's why it orbits over your doltish head.
|by Anonymous||reply 40||02/06/2013|
Even worse, he seems to think satellites are "parked" where they are because Earth's gravity is less there. Hanging motionless, perhaps?

But the Tunguska event, as I understand it, was from an asteroid about this size. It flattened things for 800 miles.
R40, if this asteroid were to hit a satellite, would it be possible for its course to be "deflected" on towards earth? Or would such a collision not slow it down or veer it off from its trajectory at all?

Satellites have very little mass relative to a large chunk of rock, so a collision with the asteroid wouldn't deflect it noticeably. Think about how much your car is deflected when it hits a fly.

Isn't 150 feet basically just a small boulder?
|by Anonymous||reply 48||02/08/2013|
150 feet is the size of half a football field. It's a fairly small size as asteroids go, but at the speed it's traveling at relative to the Earth (8X the speed of a high-powered rifle bullet), there's a lot of energy there if it were to hit.
Use this cool calculator to determine how bad the impact would be it would be if you were standing close by. Then compare it to some larger asteroids that come wandering by occasionally.
|by Anonymous||reply 49||02/08/2013|
Think of it this way:
You thow a ball really hard and it goes 20 yards and hits the ground. You throw it harder and it goes 40 yards and hits the ground.
Now imagine you are Superman. You throw the same ball from NYC really hard and fast and it lands in Moscow.
Now, you SUPER DUPER throw it so hard and fast that it NEVER lands back on Earth, in fact it goes around the Earth and passes you again and again. Suddenly, you have a satellite.

Someone up thread already explained why it couldn't be knocked off course by hitting a satellite. Basic physics.

From NASA's website:
Q: What date and what time will the asteroid be closest to Earth?
A: Asteroid 2012 DA14 will be closest to Earth on Feb. 15 at approximately 19:24 UTC (2:24 p.m. EST/11:24 a.m. PST). This time may change by a minute or two as the asteroid is tracked on its approach and predictions are refined.
At the time of closest approach, the asteroid will be over the eastern Indian Ocean, off Sumatra -- approx. latitude: -6 deg South. / longitude: 97.5 deg East.

It's not just Americans monitoring these objects, R80. Monitoring space is an international business, which includes some very, very bright people from all around the world.
