It is hard to answer your questions since there are so many stories on the news.

Many smaller meteors "burn up" during entry and others pass relative close to earth.

The closest story that I can find out is an asteroid that might hit in 2029. This story though is from 2004

The 2007 Perseid Meteor Shower Coming to a Sky Near You

This is one of the best showers of the year. The source of the shower is Comet Swift-Tuttle. Although the comet is nowhere near Earth, the comet's wide tail does intersect Earth's orbit. We glide through it every year in July and August. Tiny bits of comet dust hit Earth's atmosphere traveling 132,000 mph. At that speed, even a tiny smidgen of dust makes a vivid streak of light--a meteor--when it disintegrates. The shower is most intense when Earth is in the dustiest part of the tail.

See what happens when you only catch part of something - you don't get the right information.

Meteors are small bits of debris (most left behind by comets as they orbit the sun). When any of these bits of dust or rock enter our atmosphere, they burn up from friction and we see "shooting stars" or meteors. Most are the size of marbles or peas.

We get dozens of meteors entering our atmoshere on any one night. The story you caught part of was probably referring to the "meteor shower" that started last weekend and will end around Sept. 8, with its peak early morning (around 2:00 am) Sunday morning.
A meteor shower occurs when the Earth travels through a slightly thicker stream of this debris and the number of meteors goes up.
This is the Alpha Aurigids, with an estimated peak of about 10 meteors an hour (not a big one, but could be fun to watch).
Since the moon is just past full, its light will wash out the dimmer meteors, but there could still be some bright streaks.

The next shower is in October (the Orionids) but the big one is in December (the Geminids).

The chances of this happening today and tomorrow (and so on) are stastically the same as any other day in human history, and it has certainly happened before, so of course it is a reality that we should be concerned with.

In fact, on June 30, 1908, a meteorite estimated at around 5-6 miles in diameter exploded about 3-6 miles above an isolated area of Siberea (Tunguska), causing a 10-20 megaton explosion (about 1,000 times more than the Hirshima atomic bomb) that destroyed 830 square miles of unihabited forest.

The shockwave from this explosion also knocked people off their feet and shattered windows about 100 miles outside of the blast radius in all directions.

830 square miles is about 1/2 the size of Rhode Island and 12 times larger than Washington, DC. New York City is about 309 square miles.

So it has happened before, and fairly recently, but the catastrophe just happened to hit an unpopulated area.

The good news is that we now have the technology and funding to track objects in the sky that could possibly collide with earth. The NEAR Earth project was established in 2004 and fully funded by the federal government as of March, 2007.

With modern technology (which is only going to get better), this project officially run through 5 observatories across the globe can accurately identify and track objects as small as 140 meters in diameter DECADES before they are within proximity of the earth. They are currently tracking 4679 objects under 1 km in diameter and 715 objects over 1 km in diameter, and of these, only 2 are considered to have high priority levels, both of which are over 20 years away.

The project estimates that it is currently tracking 90+% of all objects over 1km in diameter that have any probability of passing within 1.3 AUs (1.0 AU = distance from the earth to the sun) of Earth.

With 10 years notice, our global resources and technology could surely divert any detected object.

SO, the answer to your question is that you are safer now than at ANY time in human history from the threat of a collision event, and realistically, the threat may have been virtually nutrualized altogether!!

So don't worry, be happy!!

It will come in about 359 years, but not before the Earth as we know it is wiped out shortly after Hillary Clinton and Barack Obama take office after the November 2008 elections.

Meteorites hit the Earth every day.
